RELATIONSHIPS AND PHYLOGENY

The Hexapoda form a very clearly defined class of the Arthropoda, and

many recent writers have suggested that they must have arisen

independently of other Arthropods from annelid worms, and that the

Arthropoda must, therefore, be regarded as an "unnatural," polyphyletic

assemblage. The cogent arguments against this view are set forth in the

article on Arthropoda. A near relationship between the Apterygota and

the Crustacea has been ably advocated by H. J. Hansen (1893). It is

admitted on all hands that the Hexapoda are akin to the Chilopoda.

Verhoeff has lately (1904) put forward the view that there are really

six segments in the hexapodan thorax and twenty in the abdomen--the

cerci belonging to the seventeenth abdominal segment thus showing a

close agreement with the centipede _Scolopendra_. On the other hand, G.

H. Carpenter (1899, 1902-1904) has lately endeavoured to show an exact

numerical correspondence in segmentation between the Hexapoda, the

Crustacea, the Arachnida, and the most primitive of the Diplopoda. On

either view it may be believed that the Hexapoda arose with the allied

classes from a primitive arthropod stock, while the relationships of the

class are with the Crustacea, the Chilopoda and the Diplopoda, rather

than with the Arachnida.

_Nature of Primitive Hexapoda._--Two divergent views have been held as

to the nature of the original hexapod stock. Some of those zoologists

who look to _Peripatus_, or a similar worm-like form, as representing

the direct ancestors of the Hexapoda have laid stress on a larva like

the caterpillar of a moth or saw-fly as representing a primitive stage.

On the other hand, the view of F. Muller and F. Brauer, that the

Thysanura represent more nearly than any other existing insects the

ancestors of the class, has been accepted by the great majority of

students. And there can be little doubt that this belief is justified.

The caterpillar, or the maggot, is a specialized larval form

characteristic of the most highly developed orders, while the

campodeiform larva is the starting-point for the more primitive insects.

The occurrence in the hypermetamorphic Coleoptera (see _supra_) of a

campodeiform preceding an eruciform stage in the life-history is most

suggestive. Taken in connexion with the likeness of the young among the

more generalized orders to the adults, it indicates clearly a

thysanuroid starting-point for the evolution of the hexapod orders. And

we must infer further that the specialization of the higher orders has

been accompanied by an increase in the extent of the metamorphosis--a

very exceptional condition among animals generally, as has been ably

pointed out by L. C. Miall (1895).

_Origin of Wings._--The post-embryonic growth of Hexapods with or

without metamorphosis is accompanied in most cases by the acquisition of

wings. These organs, thus acquired during the lifetime of the

individual, must have been in some way acquired during the evolution of

the class. Many students of the group, following Brauer, have regarded

the Apterygota as representing the original wingless progenitors of the

Pterygota, and the many primitive characters shown by the former group

lend support to this view. On the other hand, it has been argued that

the presence of wings in a vast majority of the Hexapoda suggests their

presence in the ancestors of the whole class. It is most unlikely that

wings have been acquired independently by various orders of Hexapoda,

and if we regard the Thysanura as the slightly modified representatives

of a primitively wingless stock, we must postulate the acquisition of

wings by some early offshoot of that stock, an offshoot whence the whole

group of the Pterygota took its rise. How wings were acquired by these

primitive Pterygota must remain for the present a subject for

speculation. Insect wings are specialized outgrowths of certain thoracic

segments, and are quite unrepresented in any other class of Arthropods.

They are not, therefore, like the wings of birds, modified from some

pre-existing structures (the fore-limbs) common to their phylum; they

are new and peculiar structures. Comparison of the tracheated wings with

the paired tracheated outgrowths on the abdominal segments of the

aquatic campodeiform larva of may-flies (see fig. 27) led C. Gegenbaur

to the brilliant suggestion that wings might be regarded as specialized

and transformed gills. But a survey of the Hexapoda as a whole, and

especially a comparative study of the tracheal system, can hardly leave

room for doubt that this system is primitively adapted for atmospheric

breathing, and that the presence of tracheal gills in larvae must be

regarded as a special adaptation for temporary aquatic life. The origin

of insect wings remains, therefore, a mystery, deepened by the

difficulty of imagining any probable use for thoracic outgrowths,

comparable to the wing-rudiments of the Exopterygota, in the early

stages of their evolution.

_Origin of Metamorphosis._--In connexion with the question whether

metamorphosis has been gradually acquired, we have to consider two

aspects, viz. the bionomic nature of metamorphosis, and to what extent

it existed in primitive insects. Bionomically, metamorphosis may be

defined as the sum of adaptations that have gradually fitted the larva

(caterpillar or maggot) for one kind of life, the fly for another. So

that we may conclude that the factors of evolution would favour its

development. With regard to its occurrence in primitive insects, our

knowledge of the geological record is most imperfect, but so far as it

goes it supports the conclusion that holometabolism (i.e. extreme

metamorphosis) is a comparatively recent phenomenon of insect life. None

of the groups of existing Endopterygota have been traced with certainty

farther back than the Mesozoic epoch, and all the numerous Palaeozoic

insect-fossils seem to belong to forms that possessed only imperfect

metamorphosis. The only doubt arises from the existence of insect

remains, referred to the order Coleoptera, in the Silesian Culm of

Steinkunzendorf near Reichenbach. The oldest larva known, _Mormolucoides

articulatus_, is from the New Red Sandstone of Connecticut; it belongs

to the _Sialidae_, one of the lowest forms of Holometabola. It is now,

in fact, generally admitted that metamorphosis has been acquired

comparatively recently, and Scudder in his review of the earliest fossil

insects states that "their metamorphoses were simple and incomplete, the

young leaving the egg with the form of the parent, but without wings,

the assumption of which required no quiescent stage before maturity."

It has been previously remarked that the phenomena of holometabolism are

connected with the development of wings inside the body (except in the

case of the fleas, where there are no wings in the perfect insect). Of

existing insects 90% belong to the Endopterygota. At the same time we

have no evidence that any Endopterygota existed amongst Palaeozoic

insects, so that the phenomena of endopterygotism are comparatively

recent, and we are led to infer that the Endopterygota owe their origin

to the older Exopterygota. In Endopterygota the wings commence their

development as invaginations of the hypodermis, while in Exopterygota

the wings begin--and always remain--as external folds or evaginations.

The two modes of growth are directly opposed, and at first sight it

appears that this fact negatives the view that Endopterygota have been

derived from Exopterygota.

Only three hypotheses as to the origin of Endopterygota can be suggested

as possible, viz.:--(1) That some of the Palaeozoic insects, though we

infer them to have been exopterygotous, were really endopterygotous, and

were the actual ancestors of the existing Endopterygota; (2) that

Endopterygota are not descended from Exopterygota, but were derived

directly from ancestors that were never winged; (3) that the predominant

division--i.e. Endopterygota--of insects of the present epoch are

descended from the predominant--if not the sole--group that existed in

the Palaeozoic epoch, viz. the Exopterygota. The first hypothesis is not

negatived by direct evidence, for we do not actually know the ontogeny

of any of the Palaeozoic insects; it is, however, rendered highly

improbable by the modern views as to the nature and origin of wings in

insects, and by the fact that the Endopterygota include none of the

lower existing forms of insects. The second hypothesis--to the effect

that Endopterygota are the descendants of apterous insects that had

never possessed wings (i.e. the Apterygogenea of Brauer and others,

though we prefer the shorter term Apterygota)--is rendered improbable

from the fact that existing Apterygota are related to Exopterygota, not

to Endopterygota, and by the knowledge that has been gained as to the

morphology and development of wings, which suggest that--if we may so

phrase it--were an apterygotous insect gradually to develop wings, it

would be on the exopterygotous system. From all points of view it

appears, therefore, probable that Endopterygota are descended from

Exopterygota, and we are brought to the question as to the way in which

this has occurred.

It is almost impossible to believe that any species of insect that has

for a long period developed the wings outside the body could change this

mode of growth suddenly for an internal mode of development of the

organs in question, for, as we have already explained, the two modes of

growth are directly opposed. The explanation has to be sought in another

direction. Now there are many forms of Exopterygota in which the

creatures are almost or quite destitute of wings. This phenomenon occurs

among species found at high elevations, among others found in arid or

desert regions, and in some cases in the female sex only, the male being

winged and the female wingless. This last state is very frequent in

_Blattidae_, which were amongst the most abundant of Palaeozoic insects.

The wingless forms in question are always allied to winged forms, and

there is every reason to believe that they have been really derived from

winged forms. There are also insects (fleas, &c.) in which metamorphosis

of a "complete" character exists, though the insects never develop

wings. These cases render it highly probable that insects may in some

circumstances become wingless, though their ancestors were winged. Such

insects have been styled anapterygotous. In these facts we have one

possible clue to the change from exopterygotism to endopterygotism,

namely, by an intermediate period of anapterygotism.

Although we cannot yet define the conditions under which exopterygotous

wings are suppressed or unusually developed, yet we know that such

fluctuations occur. There are, in fact, existing forms of Exopterygota

that are usually wingless, and that nevertheless appear in certain

seasons or localities with wings. We are therefore entitled to assume

that the suppressed wings of Exopterygota tend to reappear; and,

speaking of the past, we may say that if after a period of suppression

the wings began to reappear as hypodermal buds while a more rigid

pressure was exerted by the cuticle, the growth of the buds would

necessarily be inwards, and we should have incipient endopterygotism.

The change that is required to transform Exopterygota into Endopterygota

is merely that a cell of hypodermis should proliferate inwards instead

of outwards, or that a minute hypodermal evaginated bud should be forced

to the interior of the body by the pressure of a contracted cuticle.

If it should be objected that the wings so developed would be

rudimentary, and that there would be nothing to encourage their

development into perfect functional organs, we may remind the reader

that we have already pointed out that imperfect wings of Exopterygota

do, even at the present time under certain conditions, become perfect

organs; and we may also add that there are, even among existing

Endopterygota, species in which the wings are usually vestiges and yet

sometimes become perfectly developed. In fact, almost every condition

that is required for the change from exopterygotism to endopterygotism

exists among the insects that surround us.

But it may perhaps be considered improbable that organs like the wings,

having once been lost, should have been reacquired on the large scale

suggested by the theory just put forward. If so, there is an alternative

method by which the endopterygotous may have arisen from the

exopterygotous condition. The sub-imago of the Ephemeroptera suggests

that a moult, after the wings had become functional, was at one time

general among the Hexapoda, and that the resting nymph of the

Thysanoptera or the pupa of the Endopterygota represents a formerly

active stage in the life-history. Further, although the wing-rudiments

appear externally in an early instar of an exopterygotous insect, the

earliest instars are wingless and wing-rudiments have been previously

developing beneath the cuticle, growing however outwards, not inwards as

in the larva of an endopterygote. The change from an exopterygote to an

endopterygote development could, therefore, be brought about by the

gradual postponement to a later and later instar of the appearance of

the wing-rudiments outside the body, and their correlated growth inwards

as imaginal disks. For in the post-embryonic development of the

ancestors of the Endopterygota we may imagine two or three instars with

wing-rudiments to have existed, the last represented by the sub-imago of

the may-flies. As the life-conditions and feeding-habits of the larva

and imago become constantly more divergent, the appearance of the

wing-rudiments would be postponed to the pre-imaginal instar, and that

instar would become predominantly passive.

_Relationships of the Orders._--Reasons have been given for regarding

the Thysanura as representing, more nearly than any other living group,

the primitive stock of the Hexapoda. It is believed that insects of this

group are represented among Silurian fossils. We may conclude,

therefore, that they were preceded, in Cambrian times or earlier, by

Arthropods possessing well developed appendages on all the

trunk-segments. Of such Arthropods the living Symphyla--of which the

delicate little _Scutigerella_ is a fairly well-known example--give us

some representation.

No indications beyond those furnished by comparative anatomy help us to

unravel the phylogeny of the Collembola. In most respects, the shortened

abdomen, for example, they are more specialized than the Thysanura, and

most of the features in which they appear to be simple, such as the

absence of a tracheal system and of compound eyes, can be explained as

the result of degradation. In their insunken mouth and their jaws

retracted within the head-capsule, the Collembola resemble the

entotrophous division of the Thysanura (see APTERA), from which they are

probably descended.

From the thysanuroid stock of the Apterygota, the Exopterygota took

their rise. We have undoubted fossil evidence that winged insects lived

in the Devonian and became numerous in the Carboniferous period. These

ancient Exopterygota were synthetic in type, and included insects that

may, with probability, be regarded as ancestral to most of the existing

orders. It is hard to arrange the Exopterygota in a linear series, for

some of the orders that are remarkably primitive in some respects are

rather highly specialized in others. As regards wing-structure, the

Isoptera with the two pairs closely similar are the most primitive of

all winged insects; while in the paired mesodermal genital ducts, the

elongate cerci and the conspicuous maxillulae of their larvae the

Ephemeroptera retain notable ancestral characters. But the vestigial

jaws, numerous Malpighian tubes, and specialized wings of may-flies

forbid us to consider the order as on the whole primitive. So the

Dermaptera, which retain distinct maxillulae and have no ectodermal

genital ducts, have either specialized or aborted wings and a large

number of Malpighian tubes. The Corrodentia retain vestigial maxillulae

and two pairs of Malpighian tubes, but the wings are somewhat

specialized in the Copeognatha and absent in the degraded and parasitic

Mallophaga. The Plecoptera and Orthoptera agree in their numerous

Malpighian tubes and in the development of a folding anal area in the

hind-wing. As shown by the number and variety of species, the Orthoptera

are the most dominant order of this group. Eminently terrestrial in

habit, the differentiation of their fore-wings and hind-wings can be

traced from Carboniferous, isopteroid ancestors through intermediate

Mesozoic forms. The Plecoptera resemble the Ephemeroptera and Odonata in

the aquatic habits of their larvae, and by the occasional presence of

tufted thoracic gills in the imago exhibit an aquatic character unknown

in any other winged insects. The Odonata are in many imaginal and larval

characters highly specialized; yet they probably arose with the

Ephemeroptera as a divergent offshoot of the same primitive isopteroid

stock which developed more directly into the living Isoptera,

Plecoptera, Dermaptera and Orthoptera.

All these orders agree in the possession of biting mandibles, while

their second maxillae have the inner and outer lobes usually distinct.

The Hemiptera, with their piercing mandibles and first maxillae and with

their second maxillae fused to form a jointed beak, stand far apart from

them. This order can be traced with certainty back to the early Jurassic

epoch, while the Permian fossil _Eugereon_, and the living

order--specially modified in many respects--of the Thysanoptera indicate

steps by which the aberrant suctorial and piercing mouth of the

Hemiptera may have been developed from the biting mouth of primitive

Isopteroids, by the elongation of some parts and the suppression of

others. The Anoplura may probably be regarded as a degraded offshoot of

the Hemiptera.

The importance of great cardinal features of the life-history as

indicative of relationship leads us to consider the Endopterygota as a

natural assemblage of orders. The occurrence of weevils--among the most

specialized of the Coleoptera--in Triassic rocks shows us that this

great order of metabolous insects had become differentiated into its

leading families at the dawn of the Mesozoic era, and that we must go

far back into the Palaeozoic for the origin of the Endopterygota. In

this view we are confirmed by the impossibility of deriving the

Endopterygota from any living order of Exopterygota. We conclude,

therefore, that the primitive stock of the former sub-class became early

differentiated from that of the latter. So widely have most of the

higher orders of the Hexapoda now diverged from each other, that it is

exceedingly difficult in most cases to trace their relationships with

any confidence. The Neuroptera, with their similar fore- and hind-wings

and their campodeiform larvae, seem to stand nearest to the presumed

isopteroid ancestry, but the imago and larva are often specialized. The

campodeiform larvae of many Coleoptera are indeed far more primitive

than the neuropteran larvae, and suggest to us that the

Coleoptera--modified as their wing-structure has become--arose very

early from the primitive metabolous stock. The antiquity of the

Coleoptera is further shown by the great diversity of larval form and

habit that has arisen in the order, and the proof afforded by the

hypermetamorphic beetles that the campodeiform preceded the eruciform

larva has already been emphasized.

In all the remaining orders of the Endopterygota the larva is eruciform

or vermiform. The Mecaptera, with their predominantly longitudinal

wing-nervuration, serve as a link between the Neuroptera and the

Trichoptera, their retention of small cerci being an archaic character

which stamps them as synthetic in type, but does not necessarily remove

them from orders which agree with them in most points of structure but

which have lost the cerci. The standing of the Trichoptera in a position

almost ancestral to the Lepidoptera is one of the assured results of

recent morphological study, the mobile mandibulate pupa and the

imperfectly suctorial maxillae of the Trichoptera reappearing in the

lowest families of the Lepidoptera. This latter order, which is not

certainly known to have existed before Tertiary times, has become the

most highly specialized of all insects in the structure of the pupa.

Diptera of the sub-order Orthorrhapha occur in the Lias and Cyclorrhapha

in the Kimmeridgian. The order must therefore be ancient, and as no

evidence is forthcoming as to the mode of reduction of the hind-wings,

nor as to the stages by which the suctorial mouth-organs became

specialized, it is difficult to trace the exact relationship of the

group, but the presence of cerci and a degree of correspondence in the

nervuration of the fore-wings suggest the Mecaptera as possible allies.

There seems no doubt that the suctorial mouth-organs of the Diptera have

arisen quite independently from those of the Lepidoptera, for in the

former order the sucker is formed from the second maxillae, in the

latter from the first. The eruciform larva of the Orthorrhapha leads on

to the headless vermiform maggot of the Cyclorrhapha, and in the latter

sub-order we find metamorphosis carried to its extreme point, the muscid

flies being the most highly specialized of all the Hexapoda as regards

structure, while their maggots are the most degraded of all insect

larvae. The Siphonaptera appear by the form of the larva and the nature

of the metamorphosis to be akin to the Orthorrhapha--in which division

they have indeed been included by many students. They differ from the

Diptera, however, in the general presence of palps to both pairs of

maxillae, and in the absence of a hypopharynx, so it is possible that

their relationship to the Diptera is less close than has been supposed.

The affinities of the Hymenoptera afford another problem of much

difficulty. They differ from other Endopterygota in the multiplication

of their Malpighian tubes, and from all other Hexapoda in the union of

the first abdominal segment with the thorax. Specialized as they are in

form, development and habit, they retain mandibles for biting, and in

their lower sub-order--the Symphyta--the maxillae are hardly more

modified than those of the Orthoptera. From the evidence of fossils it

seems that the higher sub-order--Apocrita--can be traced back to the

Lias, so that we believe the Hymenoptera to be more ancient than the

Diptera, and far more ancient than the Lepidoptera. They afford an

example--paralleled in other classes of the animal kingdom--of an order

which, though specialized in some respects, retains many primitive

characters, and has won its way to dominance rather by perfection of

behaviour, and specially by the development of family life and helpful

socialism, than by excessive elaboration of structure. We would trace

the Hymenoptera back therefore to the primitive endopterygote stock. The

specialization of form in the constricted abdomen and in the suctorial

"tongue" that characterizes the higher families of the order is

correlated with the habit of careful egg-laying and provision of food

for the young. In some way it is assured among the highest of the

Hexapoda--the Lepidoptera, Diptera and Hymenoptera--that the larva finds

itself amid a rich food-supply. And thus perfection of structure and

instinct in the imago has been accompanied by degradation in the larva,

and by an increase in the extent of transformation and in the degree of

reconstruction before and during the pupal stage. The fascinating

difficulties presented to the student by the metamorphosis of the

Hexapoda are to some extent explained, as he ponders over the evolution

of the class.

HEXASTYLE (Gr. [Greek: hex], six, and [Greek: stylos], column), an

architectural term given to a temple in the portico of which there are

six columns in front.

HEXATEUCH, the name given to the first six books of the Old Testament

(the Pentateuch and Joshua), to mark the fact that these form one

literary whole, describing the early traditional history of the

Israelites from the creation of the world to the conquest of Palestine

and the origin of their national institutions. These books are the

result of an intricate literary process, on which see BIBLE (Old

Testament: _Canon_), and the articles on the separate books (GENESIS,

EXODUS, LEVITICUS, NUMBERS, DEUTERONOMY and JOSHUA).

HEXHAM, a market town in the Hexham parliamentary division of

Northumberland, England, 21 m. W. from Newcastle by the Carlisle branch

of the North-Eastern railway, served also from Scotland by a branch of

the North British railway. Pop. of urban district (1901) 7107. It is

pleasantly situated beneath the hills on the S. bank of the Tyne, and

its market square and narrow streets bear many marks of antiquity. It is

famous for its great abbey church of St Andrew. This building, as

renovated in the 12th century, was to consist of nave and transepts,

choir and aisles, and massive central tower. The Scots are believed to

have destroyed the nave in 1296, but it may be doubted if it was ever

completed. In 1536 the last prior was hanged for being concerned in the

insurrection called the Pilgrimage of Grace. The church as it stands is

a fine monument of Early English work, with Transitional details.

Within, although it suffered much loss during a restoration c. 1858,

there are several objects of interest. Among these are a Roman slab,

carved with figures of a horseman trampling upon an enemy, several fine

tombs and stones of the 13th and 14th centuries, the frith or fridstool

of stone, believed to be the original bishop's throne, and the fine

Perpendicular roodscreen of oak, retaining its loft. The crypt,

discovered in 1726, is part of the Saxon church, and a noteworthy

example of architecture of the period. Its material is Roman, some of

the stones having Roman inscriptions. These were brought from the Roman

settlement at Corbridge, 4 m. E. of Hexham on the N. bank of the Tyne;

for Hexham itself was not a Roman station. In 1832 a vessel containing

about 8000 Saxon coins was discovered in the churchyard. Fragments of

the monastic buildings remain, and west of the churchyard is the monks'

park, known as the Seal, and now a promenade, commanding beautiful

views. In the town are two strong castellated towers of the 14th

century, known as the Moot Hall and the Manor Office. Their names

explain their use, but they were doubtless also intended as defensive

works. In the interesting and beautiful neighbourhood of Hexham there

should be noticed Aydon castle near Corbridge, a fortified house of the

late 13th century; and Dilston or Dyvilston, a typical border fortress

dating from Norman times, of which only a tower and small chapel remain.

It is replete with memories of the last earl of Derwentwater, who was

beheaded in 1716 for his part in the Stuart rising of the previous year,

and was buried in the chapel. There is an Elizabethan grammar school.

Hexham and Newcastle form a Roman Catholic bishopric, with the cathedral

at Newcastle. There are manufactures of leather gloves and other goods,

and in the neighbourhood barytes and coal mines and extensive market

gardens.

The church and monastery at Hexham (Hextoldesham) were founded about 673

by Wilfrid, archbishop of York, who is said to have received a grant of

the whole of Hexhamshire from Aethelhryth, queen of Northumbria, and a

grant of sanctuary in his church from the king. The church in 678

became the head of the new see of Bernicia, which was united to that of

Lindisfarne about 821, when the bishop of Lindisfarne appears to have

taken possession of the lordship which he and his successors held until

it was restored to the archbishop of York by Henry II. The archbishops

appear to have had almost royal power throughout the liberty, including

the rights of trying all pleas of the crown in their court, of taking

inquisitions and of taxation. In 1545 the archbishop exchanged

Hexhamshire with the king for other property, and in 1572 all the

separate privileges which had belonged to him were taken away, and the

liberty was annexed to the county of Northumberland. Hexham was a

borough by prescription, and governed by a bailiff at least as early as

1276, and the same form of government continued until 1853. In 1343 the

men of Hexham were accused of pretending to be Scots and imprisoning

many people of Northumberland and Cumberland, killing some and extorting

ransoms for others. The Lancastrians were defeated in 1464 near Hexham,

and legend says that it was in the woods round the town that Queen

Margaret and her son hid until their escape to Flanders. In 1522 the

bishop of Carlisle complained to Cardinal Wolsey, then archbishop of

York, that the English thieves committed more thefts than "all the Scots

of Scotland," the men of Hexham being worst of all, and appearing 100

strong at the markets held in Hexham, so that the men whom they had

robbed dared not complain or "say one word to them." This state of

affairs appears to have continued until the accession of James I., and

in 1595 the bailiff and constables of Hexham were removed as being

"infected with combination and toleration of thieves." Hexham was at one

time the market town of a large agricultural district. In 1227 a market

on Monday and a fair on the vigil and day of St Luke the Evangelist were

granted to the archbishop, and in 1320 Archbishop Melton obtained the

right of holding two new fairs on the feasts of St James the Apostle

lasting five days and of SS. Simon and Jude lasting six days. The market

day was altered to Tuesday in 1662, and Sir William Fenwick, then lord

of the manor, received a grant of a cattle market on the Tuesday after

the feast of St Cuthbert in March and every Tuesday fortnight until the

feast of St Martin. The market rights were purchased from Wentworth B.

Beaumont, lord of the manor, in 1886. During the 17th and 18th centuries

Hexham was noted for the leather trade, especially for the manufacture

of gloves, but in the 19th century the trade began to decline. Coal

mines which had belonged to the archbishop, were sold to Sir John

Fenwick, Kt., in 1628. Hexham has never been represented in parliament,

but gives its name to one of the four parliamentary divisions of the

county.

Hexham_ (1823); James Hewitt, _A Handbook to Hexham and its

Antiquities_ (1879).

HEYDEN, JAN VAN DER (1637-1712), Dutch painter, was born at Gorcum in

1637, and died at Amsterdam on the 12th of September 1712. He was an

architectural landscape painter, a contemporary of Hobbema and Jacob

Ruysdael, with the advantage, which they lacked, of a certain

professional versatility; for, whilst they painted admirable pictures

and starved, he varied the practice of art with the study of mechanics,

improved the fire engine, and died superintendent of the lighting and

director of the firemen's company at Amsterdam. Till 1672 he painted in

partnership with Adrian van der Velde. After Adrian's death, and

probably because of the loss which that event entailed upon him, he

accepted the offices to which allusion has just been made. At no period

of artistic activity had the system of division of labour been more

fully or more constantly applied to art than it was in Holland towards

the close of the 17th century. Van der Heyden, who was perfect as an

architectural draughtsman in so far as he painted the outside of

buildings and thoroughly mastered linear perspective, seldom turned his

hand to the delineation of anything but brick houses and churches in

streets and squares, or rows along canals, or "moated granges," common

in his native country. He was a travelled man, had seen The Hague, Ghent

and Brussels, and had ascended the Rhine past Xanten to Cologne, where

he copied over and over again the tower and crane of the great

cathedral. But he cared nothing for hill or vale, or stream or wood. He

could reproduce the rows of bricks in a square of Dutch houses sparkling

in the sun, or stunted trees and lines of dwellings varied by steeples,

all in light or thrown into passing shadow by moving cloud. He had the

art of painting microscopically without loss of breadth or keeping. But

he could draw neither man nor beast, nor ships nor carts; and this was

his disadvantage. His good genius under these circumstances was Adrian

van der Velde, who enlivened his compositions with spirited figures; and

the joint labour of both is a delicate, minute, transparent work,

radiant with glow and atmosphere.

HEYLYN (or HEYLIN), PETER (1600-1662), English historian and

controversialist, was born at Burford in Oxfordshire. Having made great

progress in his studies, he entered Hart Hall, Oxford, in 1613,

afterwards joining Magdalen College; and in 1618 he began to lecture on

cosmography, being made fellow of Magdalen in the same year. His

lectures, under the title of [Greek: Mikrokosmos], were published in

1621, and many editions of this useful book, each somewhat enlarged,

subsequently appeared. Having been ordained in 1624 Heylyn attracted the

notice of William Laud, then bishop of Bath and Wells; and in 1628 he

married Laetitia, daughter of Thomas Highgate, or Heygate, of Hayes,

Middlesex; but he appears to have kept his marriage secret and did not

resign his fellowship. After serving as chaplain to Danby in the Channel

Islands, he became chaplain to Charles I. in 1630, and was appointed by

the king to the rectory of Hemingford, Huntingdonshire. John Williams,

bishop of Lincoln, however, refused to institute Heylyn to this living,

owing to his friendship with Laud; and in return Charles appointed him a

prebendary of Westminster, where he made himself very objectionable to

Williams, who held the deanery _in commendam_. In 1633 he became rector

of Alresford, soon afterwards vicar of South Warnborough, and he became

treasurer of Westminster Abbey in 1637; but before this date he was

widely known as one of the most prominent and able controversialists

among the high-church party. Entering with great ardour into the

religious controversies of the time he disputed with John Prideaux,

regius professor of divinity at Oxford, replied to the arguments of

Williams in his pamphlets, "A Coal from the Altar" and "Antidotum

Lincolnense," and was hostile to the Puritan element both within and

without the Church of England. He assisted William Noy to prepare the

case against Prynne for the publication of his _Histriomastix_, and made

himself useful to the Royalist party in other ways. However, when the

Long Parliament met he was allowed to retire to Alresford, where he

remained until he was disturbed by Sir William Waller's army in 1642,

when he joined the king at Oxford. At Oxford Heylyn edited _Mercurius

Aulicus_, a vivacious but virulent news-sheet, which greatly annoyed the

Parliamentarians; and consequently his house at Alresford was plundered

and his library dispersed. Subsequently he led for some years a

wandering life of poverty, afterwards settling at Winchester and then at

Minster Lovel in Oxfordshire; and he refers to his hardships in his

pamphlet "Extraneus Vapulans," the cleverest of his controversial

writings, which was written in answer to Hamon l'Estrange. In 1653 he

settled at Lacy's Court, Abingdon, where he resided undisturbed by the

government of the Commonwealth, and where he wrote several books and

pamphlets, both against those of his own communion, like Thomas Fuller,

whose opinions were less unyielding than his own, and against the

Presbyterians and others, like Richard Baxter.

His works, all of which are marred by political or theological rancour,

number over fifty. Among the most important are: a legendary and learned

_History of St. George of Cappadocia_, written in 1631; _Cyprianus

Anglicus, or the history of the Life and Death of William Laud_, a

defence of Laud and a valuable authority for his life; _Ecclesia

restaurata, or the History of the Reformation of the Church of England_

(1661; ed. J. C. Robertson, Cambridge, 1849); _Ecclesia vindicata, or

the Church of England justified_; _Aerius redivivus, or History of the

Presbyterians_; and _Help to English History_, an edition of which, with

additions by P. Wright, was published in 1773. In 1636 he wrote a

_History of the Sabbath_, by order of Charles I. to answer the Puritans;

and in consequence of a journey through France in 1625 he wrote _A

Survey of France_, a work, frequently reprinted, which was termed by

Southey "one of the liveliest books of travel in its lighter parts, and

one of the wisest and most replete with information that was ever

written by a young man." Some verses of merit also came from his active

pen, and his poetical memorial of William of Waynflete was published by

the Caxton Society in 1851.

Heylyn was a diligent writer and investigator, a good ecclesiastical

lawyer, and had always learning at his command. His principles, to which

he was honestly attached, were defended with ability; but his efforts to

uphold the church passed unrecognized at the Restoration, probably owing

to his physical infirmities. His sight had been very bad for several

years; yet he rejoiced that his "bad old eyes" had seen the king's

return, and upon this event he preached before a large audience in

Westminster Abbey on the 29th of May 1661. He died on the 8th of May

1662 and was buried in Westminster Abbey, where he had been sub-dean for

some years.

Lives of Heylyn were written by his son-in-law Dr John Barnard or

Bernard, and by George Vernon (1682). Bernard's work was reprinted

with Robertson's edition of Heylyn's _History of the Reformation_ in

1849.

HEYN, PIETER PIETERZOON [commonly abbreviated to PIET] (1578-1629),

Dutch admiral, was born at Delfshaven in 1578, the son of Pieter Hein,

who was engaged in the herring fishery. The son went early to sea. In

his youth he was taken prisoner by the Spaniards, and was forced to row

in the galleys during four years. Having recovered his freedom by an

exchange of prisoners, he worked for several years as a merchant skipper

with success. The then dangerous state of the seas at all times, and the

continuous war with Spain, gave him ample opportunity to gain a

reputation as a resolute fighting man. Wills which he made before 1623

show that he had been able to acquire considerable property. When the

Dutch West India Company was formed he was Director on the Rotterdam

Board, and in 1624 he served as second in command of the fleet which

took San Salvador in Bahia de Todos os Santos in Brazil. Till 1628 he

continued to serve the Company, both on the coast of Brazil, and in the

West Indies. In the month of September of that year he made himself

famous, gained immense advantage for the Company, and inflicted ruinous

loss on the Spaniards, by the capture of the fleet which was bringing

the bullion from the American mines home to Spain. The Spanish ships

were outnumbered chiefly because the convoy had become scattered by bad

management and bad seamanship. The more valuable part of it, consisting

of the four galleons, and eleven trading ships in which the king's share

of the treasure was being carried, became separated from the rest, and

on being chased by the superior force of Heyn endeavoured to take refuge

at Matanzas in the island of Cuba, hoping to be able to land the bullion

in the bush before the Dutchman could come up with them. But Juan de

Benavides, the Spanish commander, failed to act with decision, was

overtaken, and his ships captured in the harbour before the silver could

be discharged. The total loss was estimated by the Spaniards at four

millions of ducats. Piet Heyn now returned home, and bought himself a

house at Delft with the intention of retiring from the sea. In the

following year, however, he was chosen at a crisis to take command of

the naval force of the Republic, with the rank of Lieutenant-Admiral of

Holland, in order to clear the North Sea and Channel of the Dunkirkers,

who acted for the king of Spain in his possessions in the Netherlands.

In June of 1629 he brought the Dunkirkers to action, and they were

severely beaten, but Piet Heyn did not live to enjoy his victory. He was

struck early in the battle by a cannon shot on the shoulder and fell

dead on the spot. His memory has been preserved by his capture of the

Treasure Galleons, which had never been taken so far, but he is also

the traditional representative of the Dutch "sea dogs" of the 17th

century.

HEYNE, CHRISTIAN GOTTLOB (1729-1812), German classical scholar and

archaeologist, was born on the 25th of September 1729, at Chemnitz in

Saxony. His father was a poor weaver, and the expenses of his early

education were paid by one of his godfathers. In 1748 he entered the

university of Leipzig, where he was frequently in want of the

necessaries of life. His distress had almost amounted to despair, when

he procured the situation of tutor in the family of a French merchant in

Leipzig, which enabled him to continue his studies. After he had

completed his university course, he was for many years in very

straitened circumstances. An elegy written by him in Latin on the death

of a friend attracted the attention of Count von Bruhl, the prime

minister, who expressed a desire to see the author. Accordingly, in

April 1752, Heyne journeyed to Dresden, believing that his fortune was

made. He was well received, promised a secretaryship and a good salary,

but nothing came of it. Another period of want followed, and it was only

by persistent solicitation that Heyne was able to obtain the post of

under-clerk in the count's library, with a salary of somewhat less than

twenty pounds sterling. He increased his scanty pittance by translation;

in addition to some French novels, he rendered into German the _Chaereas

and Callirrhoe_ of Chariton, the Greek romance writer. He published his

first edition of _Tibullus_ in 1755, and in 1756 his _Epictetus_. In the

latter year the Seven Years' War broke out, and Heyne was once more in a

state of destitution. In 1757 he was offered a tutorship in the

household of Frau Von Schonberg, where he met his future wife. In

January 1759 he accompanied his pupil to the university of Wittenberg,

from which he was driven in 1760 by the Prussian cannon. The bombardment

of Dresden (to which city he had meanwhile returned) on the 18th of July

1760, destroyed all his possessions, including an almost finished

edition of Lucian, based on a valuable codex of the Dresden Library. In

the summer of 1761, although still without any fixed income, he married,

and for some time he found it necessary to devote himself to the duties

of land-steward to the Baron von Loben in Lusatia. At the end of 1762,

however, he was enabled to return to Dresden, where he was commissioned

by P. D. Lippert to prepare the Latin text of the third volume of his

_Dactyliotheca_ (an account of a collection of gems). On the death of

Johann Matthias Gesner at Gottingen in 1761, the vacant chair was

refused first by Ernesti and then by Ruhnken, who persuaded Munchhausen,

the Hanoverian minister and principal curator of the university, to

bestow it on Heyne (1763). His emoluments were gradually augmented, and

his growing celebrity brought him most advantageous offers from other

German governments, which he persistently refused. After a long and

useful career, he died on the 14th of July 1812. Unlike Gottfried

Hermann, Heyne regarded the study of grammar and language only as the

means to an end, not as the chief object of philology. But, although not

a critical scholar, he was the first to attempt a scientific treatment

of Greek mythology, and he gave an undoubted impulse to philological

studies.

Of Heyne's numerous writings, the following may be mentioned.

Editions, with copious commentaries, of Tibullus (ed. E. C.

Wunderlich, 1817), Virgil (ed. G. P. Wagner, 1830-1841), Pindar (3rd

ed. by G. H. Schafer, 1817), Apollodorus, _Bibliotheca Graeca_ (1803),

Homer, _Iliad_ (1802); _Opuscula academica_ (1785-1812), containing

more than a hundred academical dissertations, of which the most

valuable are those relating to the colonies of Greece and the

antiquities of Etruscan art and history. His _Antiquarische Aufsatze_

(1778-1779) is a valuable collection of essays connected with the

history of ancient art. His contributions to the _Gottingische

gelehrte Anzeigen_ are said to have been between 7000 and 8000 in

number. See biography by A. H. Heeren (1813) which forms the basis of

the interesting essay by Carlyle (_Misc. Essays_, ii.); H. Sauppe,

_Gottinger Professoren_ (1872); C. Bursian in _Allgemeine deutsche

Biographie_, xii.; J. E. Sandys, _Hist. Class. Schol._ iii. 36-44.

HEYSE, PAUL JOHANN LUDWIG (1830- ), German novelist, dramatist and

poet, was born at Berlin on the 15th of March 1830, the son of the

distinguished philologist Karl Wilhelm Ludwig Heyse (1797-1855). After

attending the Friedrich Wilhelm Gymnasium in Berlin, he went, in 1849,

to Bonn University as a student of the Romance languages, and in 1852

took his doctor's degree. He had already given proof of great literary

ability in the production in 1850 of _Der Jungbrunnen, Marchen eines

fahrenden Schulers_ and of the tragedy _Francesca von Rimini_, when

after a year's stay in Italy, he was summoned, early in 1854, by King

Maximilian II. to Munich, where he subsequently lived. Here he turned

his attention to novel-writing. He published at Munich in 1855 four

short stories in one volume, one of which, at least, _L'Arrabbiata_, was

a masterpiece of its kind. These were the precursors of a series of

similar volumes, necessarily unequal at times, but on the whole

constituting such a mass of highly complex miniature fiction as seldom

before had proceeded from the pen of a single writer. Heyse works in the

spirit of a sculptor; he seizes upon some picturesque incident or

situation, and chisels and polishes until all the effect which it is

capable of producing has been extracted from it. The success of the

story usually depends upon the theme, for the artist's skill is

generally much the same, and the situation usually leaves a deeper

impression than the characters. Heyse is also the author of several

novels on a larger scale, all of which have gained success and provoked

abundant discussion. The more important are _Kinder der Welt_ (1873),

_Im Paradiese_ (1875)--the one dealing with the religious and social

problems of its time, the other with artist-life in Munich--_Der Roman

der Stiftsdame_ (1888), and _Merlin_ (1892), a novel directed against

the modern realistic movement of which Heyse had been the leading

opponent in Germany. He has also been a prolific dramatist, but his

plays are deficient in theatrical qualities and are rarely seen on the

stage. Among the best of them are _Die Sabinerinnen_ (1859); _Hans

Lange_ (1866), _Kolberg_ (1868), _Die Weisheit Salomos_ (1886), and

_Maria von Magdala_ (1903). There are masterly translations by him of

Leopardi, Giusti, and other Italian poets (_Italienische Dichter seit

der Mitte des 18ten Jahrhundert_) (4 vols., 1889-1890).

Heyse's _Gesammelte Werke_ appeared in 29 vols. (1897-1899); there is

also a popular edition of his _Romane_ (8 vols., 1902-1904) and

_Novellen_ (10 vols., 1904-1906). See his autobiography,

_Jugenderinnerungen und Bekenntnisse_ (1901); also O. Kraus, _Paul

Heyses Novellen und Romane_ (1888); E. Petzet, _Paul Heyse als

Dramatiker_ (1904), and the essays by T. Ziegler (in _Studien und

Studienkopfe_, 1877), and G. Brandes (in _Moderne Geister_, 1887).

HEYSHAM, a seaport in the Lancaster parliamentary division of

Lancashire, England, on the south shore of Morecambe Bay, served by the

Midland railway. Pop. (1901) 3381. Under powers obtained from parliament

in 1896, the Midland Railway Company constructed, and opened in 1904, a

harbour, enclosed by breakwaters, for the development of traffic with

Belfast and other Irish ports, a daily passenger-service of the first

class being established to Belfast. The harbour has a depth at low tide

of 17 ft., and extensive accommodation for live-stock and goods of all

kinds is provided. Heysham is in some favour as a watering-place. The

church of St Peter is mainly Norman, and has fragments of even earlier

date. Ruins of a very ancient oratory stand near it. This was dedicated

to St Patrick, and is traditionally said to have been erected as a place

of prayer for those at sea.

HEYWOOD, JOHN (b. 1497), English dramatist and epigrammatist, is

generally said to have been a native of North Mimms, near St Albans,

Hertfordshire, though Bale says he was born in London. A letter from a

John Heywood, who may fairly be identified with him, is dated from

Malines in 1575, when he called himself an old man of seventy-eight,

which would fix his birth in 1497. He was a chorister of the Chapel

Royal, and is said to have been educated at Broadgates Hall (Pembroke

College), Oxford. From 1521 onwards his name appears in the king's

accounts as the recipient of an annuity of ten marks as player of the

virginals, and in 1538 he received forty shillings for "playing an

interlude with his children" before the Princess Mary. He is said to

have owed his introduction to her to Sir Thomas More, at whose seat at

Gobions near St Albans he wrote his Epigrams, according to Henry

Peacham. More took a keen interest in the drama, and is represented by

tradition as stepping on to the stage and taking an impromptu part in

the dialogue. William Rastell, the printer of four of Heywood's plays,

was the son of More's brother-in-law, John Rastell, who organized

dramatic representations, and possibly wrote plays himself. Mr A. W.

Pollard sees in Heywood's firm adherence to Catholicism and his free

satire of legal and social abuses a reflection of the ideas of More and

his friends, which counts for much in his dramatic development. His

skill in music and his inexhaustible wit made him a favourite both with

Henry VIII. and Mary. Under Edward VI. he was accused of denying the

king's supremacy over the church, and had to make a public recantation

in 1554; but with the accession of Mary his prospects brightened. He

made a Latin speech to her in St Paul's Churchyard at her coronation,

and wrote a poem to celebrate her marriage. Shortly before her death she

granted him the lease of a manor and lands in Yorkshire. When Elizabeth

succeeded to the throne he fled to Malines, and is said to have returned

in 1577. In 1587 he is spoken of as "dead and gone" in Thomas Newton's

epilogue to his works.

John Heywood is important in the history of English drama as the first

writer to turn the abstract characters of the morality plays into real

persons. His interludes link the morality plays to the modern drama, and

were very popular in their day. They represent ludicrous incidents of a

homely kind in a style of the broadest farce, and approximate to the

French dramatic renderings of the subjects of the _fabliaux_. The fun in

them still survives in spite of the long arguments between the

characters and what one of their editors calls his "humour of filth."

Heywood's name was actually attached to four interludes. _The Playe

called the foure PP; a newe and a very mery interlude of a palmer, a

pardoner, a potycary, a pedler_ (not dated) is a contest in lying,

easily won by Palmer, who said he had never known a woman out of

patience. _The Play of the Wether, a new and a very mery interlude of

all maner of Wethers_ (printed 1533) describes the chaotic results of

Jupiter's attempts to suit the weather to the desires of a number of

different people. _The Play of Love_ (printed 1533) is an extreme

instance of the author's love of wire-drawn argument. It is a double

dispute between "Loving not Loved" and "Loved not Loving" as to which is

the more wretched, and between "Both Loved and Loving" and "Neither

Loving nor Loved" to decide which is the happier. The only action in

this piece is indicated by the stage direction marking the entrance of

"Neither loved nor loving," who is to run about the audience with a huge

copper tank on his head full of lighted squibs, and is to cry "Water,

water! Fire, fire!" _The Dialogue of Wit and Folly_ is more of an

academic dispute than a play. But two pieces universally assigned to

Heywood, although they were printed by Rastell without any author's

name, combine action with dialogue, and are much more dramatic. In _The

Mery Play between the Pardoner and the Frere, the Curate and Neybour

Pratte_ (printed 1533, but probably written much earlier) the Pardoner

and the Friar both try to preach at the same time, and, coming at last

to blows, are separated by the other two personages of the piece. The

_Mery Play betwene Johan Johan the Husbande, Tyb the Wyfe, and Syr Jhan

the Preest_ (printed 1533) is the best constructed of all his pieces.

Tyb and Syr Jhan eat the "Pye" which is the central "property" of the

piece, while Johan Johan is made to chafe wax at the fire to stop a hole

in a pail. This incident occurs in a French _Farce nouvelle tres bonne

et fort joyeuse de Pernet qui va au vin_. Heywood has sometimes been

credited with the authorship of the dialogue of _Gentylnes and Nobylyte_

printed by Rastell without date, and Mr Pollard adduces some ground for

attributing to him the anonymous _New Enterlude called Thersytes_

(played 1538). Heywood's other works are a collection of proverbs and

epigrams, the earliest extant edition of which is dated 1562; some

ballads, one of them being the "Willow Garland," known to Desdemona;

and a long verse allegory of over 7000 lines entitled _The Spider and

the Flie_ (1556). A contemporary writer in Holinshed's _Chronicle_ said

that neither its author nor any one else could "reach unto the meaning

thereof." But the flies are generally taken to represent the Roman

Catholics and the spiders the Protestants, while Queen Mary is

represented by the housemaid who with her broom (the sword) executes the

commands of her master (Christ) and her mistress (the church). Dr A. W.

Ward speaks of its "general lucidity and relative variety of treatment."

Heywood says that he laid it aside for twenty years before he finished

it, and, whatever may be the final interpretation put upon it, it

contains a very energetic statement of the social evils of the time, and

especially of the deficiencies of English law.

The proverbs and epigrams were reprinted by the Spenser Society in

1867, the _Dialogue on Wit and Folly_ by the Percy Society from an MS.

in the British Museum in 1846, with an account of Heywood by F. W.

Fairholt, and there are modern reprints of _Johan Johan_ (Chiswick

Press, 1819), _The Foure PP_. (Dodsley's _Old Plays_, 1825, 1874), and

_The Pardoner and the Frere_ (Dodsley's _Old Plays_, 1874). _The

Spider and the Flie_ was edited by A. W. Ward for the Spenser Society

in 1894. For notes and strictures on that edition see J. Haber in

_Litterarhistorische Forschungen_, vol. xv. (1900). See also A. W.

Pollard's introduction to the reprint of the _Play of the Wether_ and

_Johan Johan in Representative English Comedies_ (1903), and _The

Dramatic Writings of John Heywood_, edited by John S. Farmer for the

Early English Drama Society (1905).

His son, JASPER HEYWOOD (1535-1598), who translated into English three

plays of Seneca, the _Troas_ (1559), the _Thyestes_ (1560) and _Hercules

Furens_ (1561), was a fellow of Merton College, Oxford, but was

compelled to resign from that society in 1558. In the same year he was

elected a fellow of All Souls College, but, refusing to conform to the

changes in religion at the beginning of the reign of Elizabeth, he gave

up his fellowship and went to Rome, where he was received into the

Society of Jesus. For seventeen years he was professor of moral theology

and controversy in the Jesuit College at Dillingen, Bavaria. In 1581 he

was sent to England as superior of the Jesuit mission, but his leniency

in that position led to his recall. He was on his way back to the

Continent when a violent storm drove him back to the English coast. He

was arrested on the charge of being a priest, but, although

extraordinary efforts were made to induce him to abjure his opinions, he

remained firm. He was condemned to perpetual exile on pain of death, and

died at Naples on the 9th of January 1598. His translations of Seneca

were supplemented by other plays contributed by Alexander Neville,

Thomas Nuce, John Studley and Thomas Newton. Newton collected these

translations in one volume, _Seneca, his tenne tragedies translated into

Englysh_ (1581). The importance of this work in the development of

English drama can hardly be over-estimated.

See Dr J. W. Cunliffe, _On the Influence of Seneca upon Elizabethan

Tragedy_ (1893).

HEYWOOD, THOMAS (d. c. 1650), English dramatist and miscellaneous

author, was a native of Lincolnshire, born about 1575, and said to have

been educated at Cambridge and to have become a fellow of Peterhouse.

Heywood is mentioned by Philip Henslowe as having written a book or play

for the Lord Admiral's company of actors in October 1596; and in 1598 he

was regularly engaged as a player in the company, in which he presumably

had a share, as no wages are mentioned. He was also a member of other

companies, of Lord Southampton's, of the earl of Derby's and of the earl

of Worcester's players, afterwards known as the Queen's Servants. In his

preface to the _English Traveller_ (1633) he describes himself as having

had "an entire hand or at least a main finger in two hundred and twenty

plays." Of this number, probably considerably increased before the close

of his dramatic career, only twenty-three survive. He wrote for the

stage, not for the press, and protested against the printing of his

works, which he said he had no time to revise. He was, said Tieck, the

"model of a light and rapid talent," and his plays, as might be expected

from his rate of production, bear little trace of artistic elaboration.

Charles Lamb called him a "prose Shakespeare"; Professor Ward, one of

Heywood's most sympathetic editors, points out that this epigrammatic

statement can only be accepted with reservations. Heywood had a keen eye

for dramatic situations and great constructive skill, but his powers of

characterization were not on a par with his stagecraft. He delighted in

what he called "merry accidents," that is, in coarse, broad farce; his

fancy and invention were inexhaustible. It was in the domestic drama of

sentiment that he won his most distinctive success. For this he was

especially fitted by his genuine tenderness and his freedom from

affectation, by the sweetness and gentleness for which Lamb praised him.

His masterpiece, _A Woman kilde with kindnesse_ (acted 1603; printed

1607), is a type of the _comedie larmoyante_, and _The English

Traveller_ (1633) is a domestic tragedy scarcely inferior to it in

pathos and in the elevation of its moral tone. His first play was

probably _The Foure Prentises of London: With the Conquest of Jerusalem_

(printed 1615, but acted some fifteen years earlier). This may have been

intended as a burlesque of the old romances, but it is more likely that

it was meant seriously to attract the apprentice public to whom it was

dedicated, and its popularity was no doubt aimed at in Beaumont and

Fletcher's travesty of the City taste in drama in their _Knight of the

Burning Pestle_. The two parts of _King Edward the Fourth_ (printed

1600), and of _If you know not me, you know no bodie; Or, The Troubles

of Queene Elizabeth_ (1605 and 1606) are chronicle histories. His other

comedies include: _The Royall King, and the Loyall subject_ (acted c.

1600; printed 1637); the two parts of _The Fair Maid of the West; Or, A

Girle worth Gold_ (two parts, printed 1631); _The Fayre Maid of the

Exchange_ (printed anonymously 1607); _The Late Lancashire Witches_

(1634), written with Richard Brome, and prompted by an actual trial in

the preceding year; _A Pleasant Comedy, called A Mayden-Head well lost_

(1634); _A Challenge for Beautie_ (1636); _The Wise-Woman of Hogsdon_

(printed 1638), the witchcraft in this case being matter for comedy, not

seriously treated as in the Lancashire play; and _Fortune by Land and

Sea_ (printed 1655), with William Rowley. The five plays called

respectively _The Golden_, _The Silver_, _The Brazen_ and _The Iron Age_

(the last in two parts), dated 1611, 1613, 1613, 1632, are series of

classical stories strung together with no particular connexion except

that "old Homer" introduces the performers of each act in turn. _Loves

Maistresse; Or, The Queens Masque_ (printed 1636) is on the story of

Cupid and Psyche as told by Apuleius; and the tragedy of the _Rape of

Lucrece_ (1608) is varied by a "merry lord," Valerius, who lightens the

gloom of the situation by singing comic songs. A series of pageants,

most of them devised for the City of London, or its guilds, by Heywood,

were printed in 1637. In vol. iv. of his _Collection of Old English

Plays_ (1885), Mr A. H. Bullen printed for the first time a comedy by

Heywood, _The Captives, or The Lost Recovered_ (licensed 1624), and in

vol. ii. of the same series, _Dicke of Devonshire_, which he tentatively

assigns to the same hand.

Besides his dramatic works, twelve of which were reprinted by the

"Shakespeare Society," and were published by Mr John Pearson in a

complete edition of six vols. with notes and illustrations in 1874, he

was the author of _Troia Britannica, or Great Britain's Troy_ (1609), a

poem in seventeen cantos "intermixed with many pleasant poetical tales"

and "concluding with an universal chronicle from the creation until the

present time"; _An Apology for Actors, containing three brief treatises_

(1612) edited for the Shakespeare Society in 1841; [Greek: Gynaikeion]

_or nine books of various history concerning women_ (1624); _England's

Elizabeth, her Life and Troubles during her minority from the Cradle to

the Crown_ (1631); _The Hierarchy of the Blessed Angels_ (1635), a

didactic poem in nine books; _Pleasant Dialogue, and Dramas selected out

of Lucian_, &c. (1637; ed. W. Bang, Louvain, 1903); and _The Life of

Merlin surnamed Ambrosius_ (1641).

HEYWOOD, a municipal borough in the Heywood parliamentary division of

Lancashire, England, 9 m. N. of Manchester on the Lancashire and

Yorkshire railway. Pop. (1901) 25,458. It is of modern growth and

possesses several handsome churches, chapels and public buildings. The

Queen's Park, purchased and laid out at a cost of L11,000 with money

which devolved to Queen Victoria in right of her duchy and county

palatine of Lancaster, was opened in 1879. Heywood Hall in the

neighbourhood of the town was the residence of Peter Heywood, who

contributed to the discovery of the Gunpowder Plot. Heywood owes its

rise to the enterprise of the Peels, its first manufactures having been

introduced by the father of the first Sir Robert Peel. It is an

important seat of the cotton manufacture, and there are power-loom

factories, iron foundries, chemical works, boiler-works and railway

wagon works. Coal is worked extensively in the neighbourhood. Heywood

was incorporated in 1881, and the corporation consists of a mayor, 6

aldermen and 18 councillors. Area, 3660 acres.

HEZEKIAH (Heb. for "[my] strength is [of] Yah"), in the Bible son of

Ahaz, one of the greatest of the kings of Judah. He flourished at the

end of the 8th and beginning of the 7th century B.C., when Palestine

passed through one of the most eventful periods of its history. There is

much that is uncertain in his reign, and with the exception of the great

crisis of 701 B.C. its chronology has not been unanimously fixed.

Whether he came to the throne before or after the fall of Samaria

(722-721 B.C.) is disputed,[1] nor is it clear what share Judah took in

the Assyrian conflicts down to 701.[2] Shortly before this date the

whole of western Asia was in a ferment; Sargon had died and Sennacherib

had come to the throne (in 705); vassal kings plotted to recover their

independence and Assyrian puppets were removed by their opponents. Judah

was in touch with a general rising in S.W. Palestine, in which Ekron,

Lachish, Ascalon (Ashkelon) and other towns of the Philistines were

supported by the kings of Musri and Meluhha.[3] Sennacherib completely

routed them at Eltekeh (a Danite city), and thence turned against

Hezekiah, who had been in league with Ekron and had imprisoned its king

Padi, an Assyrian vassal. In this invasion of Judah the Assyrian claims

entire success; 46 towns of Judah were captured, 200,150 men and many

herds of cattle were carried off among the spoil, and Jerusalem itself

was closely invested. Hezekiah was imprisoned "like a bird in a

cage"[4]--to quote Sennacherib, and the Urbi (Arabian?) troops in

Jerusalem laid down their arms. Thirty talents of gold, eight hundred of

silver, precious stones, couches and seats of ivory--"all kinds of

valuable treasure",--the ladies of the court, male and female attendants

(perhaps "singers") were carried away to Nineveh. Here the Assyrian

record ends somewhat abruptly, for, in the meanwhile, Babylonia had

again revolted (700 B.C.) and Sennacherib's presence was urgently needed

nearer home.

At what precise period the Babylonian Merodach (i.e. Marduk)-Baladan

sent his embassy to Hezekiah is disputed. Although ostensibly to

congratulate the king upon his recovery from a sickness, it was really

sent in the hope of enlisting his support, and the excessive courtesy

and complaisance with which it was received suggest that it found a

ready ally in Judah (2 Kings xx. 12 sqq.; Isa. xxxix.). Merodach-Baladan

was overthrown by Sargon in 710 B.C., but succeeded in making a fresh

revolt some years later (704-703 B.C.), and opinion is much divided

whether his embassy was to secure the friendship of the youthful

Hezekiah at his succession or is to be associated with the later

widespread attempt to remove the Assyrian yoke.[5]

The brief account of the Assyrian invasion, Hezekiah's submission, and

the payment of tribute in 2 Kings xviii. 14-16, supplements the Assyrian

record by the statement that Sennacherib besieged Lachish, a fact which

is confirmed by a bas-relief (now in the British Museum) depicting the

king in the act of besieging that town.[6] This thoroughly historical

fragment is followed by two narratives which tell how the king sent an

official from Lachish to demand the submission of Hezekiah and conclude

with the unexpected deliverance of Jerusalem. Both these stories appear

to belong to a biography of Isaiah, and, like the similar biographies of

Elijah and Elisha, are open to the suspicion that historical facts have

been subordinated to idealize the work of the prophet. See KINGS, BOOKS

OF.

The narratives are (a) 2 Kings xviii. 13, 17-xix. 8; cf. Isa. xxxvi.

1-xxxvii. 8, and (b) xix. 9b-35; cp. Isa. xxxvii. 9-36 (2 Chron.

xxxii. 9 sqq. is based on both), and Jerusalem's deliverance is

attributed to a certain rumour (xix. 7), to the advance of Tirhakah,

king of Ethiopia (v. 9), and to a remarkable pestilence (v. 35) which

finds an echo in a famous story related, not without some confusion of

essential facts, by Herodotus (ii. 141; cf. Josephus _Antiq._ x. i.

5).[7] It is difficult to decide whether xix. 9a belongs to the first

or second of these narratives; and whether the "rumour" refers to the

approach of Tirhakah, or rather to the serious troubles which had

arisen in Babylonia. It is equally difficult to determine whether

Tirhakah actually appeared on the scene in 701, and the precise

application of the term Musri (Mizraim) is much debated. Unless the

two narratives are duplicates of the same event, it may be urged that

Sennacherib's attack upon Arabia (apparently about 689) involved an

invasion of Judah, by which time Egypt was in a position to be of

material assistance (cf. Isa. xxx. 1-5, xxxi. 1-3?). This theory of a

second campaign (first suggested by Sir Henry Rawlinson) has been

contested, although it is pointed out that Sennacherib at all events

did not invade Egypt, and that 2 Kings xix. 24 (Isa. xxxvii. 25) can

only refer to his successor. The allusion to the murder of Sennacherib

(xix. 36 sq.)[8] points to the year 681, but it is uncertain to which

of the above narratives it belongs. On the whole, the question must be

left open, and with it both the problem of the extension of the name

Musri and Mizraim outside Egypt in the Assyrian and Hebrew records of

this period and the true historical background of a number of the

Isaianic prophecies. It is quite possible that later events which

belong to the time of the Egyptian supremacy and the wars of

Esarhaddon have been confused with the history of Sennacherib's

invasion.

It is not certain whether Hezekiah's conflict with the Philistines as

far as Gaza or his preparations to secure for Jerusalem a good water

supply (xviii. 8, xx. 20; 2 Chron. xxxii. 30; Ecclus. xlviii. 17 sq.)[9]

should precede or follow the events which have been discussed. On the

other hand, the reforms which the compiler of the book has attributed to

the early part of the reign were doubtless much later (2 Kings xviii.

1-8). Not the fall of Samaria, but the crisis of 701, is the earliest

date that could safely be chosen, and the extent of these reforms must

not be overestimated. They are related in terms that imply an

acquaintance with the great "Deuteronomic" movement (see DEUTERONOMY),

and are magnified further with characteristic detail by the chronicler

(2 Chron. xxix.-xxxi.). The most remarkable was the destruction of a

brazen serpent, the cult of which was traditionally traced back to the

time of Moses (Num. xxi. 9).[10] This persistence of serpent-cult, and

the idolatry (necromancy, tree-worship) which the contemporary prophets

denounce, do not support the view that the apparently radical reforms of

Hezekiah were extensive or permanent, and Jer. xxvi. 17-19 (which

suggests that Micah had a greater influence than Isaiah) throws another

light upon the conditions during his reign. Hezekiah was succeeded by

his son MANASSEH (q.v.).

See further W. R. Smith, _Prophets_, 359-364, and HEBREW RELIGION.

According to PROV. xxv. 1, Hezekiah was a patron of literature (see

PROVERBS). The hymn which is ascribed to the king (Isa. xxxviii. 9-20,

wanting in 2 Kings) is of post-exilic origin (see Cheyne, _Introd. to

Isaiah_, 222 sq.), but is further proof of the manner in which the

Judaean king was idealized in subsequent ages, partly, perhaps, in the

belief that the deliverance of Jerusalem was the reward for his piety.
