CHAPTER II

THE SPREAD OF CONQUEST IN THE ANCIENT WORLD

In a companion volume of this series, "The Story of Extinct

Civilisations in the East," will be found an account of the rise

and development of the various nations who held sway over the west

of Asia at the dawn of history. Modern discoveries of remarkable

interest have enabled us to learn the condition of men in Asia

Minor as early as 4000 B.C. All these early civilisations existed

on the banks of great rivers, which rendered the land fertile through

which they passed.

We first find man conscious of himself, and putting his knowledge

on record, along the banks of the great rivers Nile, Euphrates,

and Tigris, Ganges and Yang-tse-Kiang. But for our purposes we

are not concerned with these very early stages of history. The

Egyptians got to know something of the nations that surrounded

them, and so did the Assyrians. A summary of similar knowledge

is contained in the list of tribes given in the tenth chapter of

Genesis, which divides all mankind, as then known to the Hebrews,

into descendants of Shem, Ham, and Japhet--corresponding, roughly,

to Asia, Europe, and Africa. But in order to ascertain how the

Romans obtained the mass of information which was summarised for

them by Ptolemy in his great work, we have merely to concentrate

our attention on the remarkable process of continuous expansion

which ultimately led to the existence of the Roman Empire.

All early histories of kingdoms are practically of the same type.

A certain tract of country is divided up among a certain number

of tribes speaking a common language, and each of these tribes

ruled by a separate chieftain. One of these tribes then becomes

predominant over the rest, through the skill in war or diplomacy

of one of its chiefs, and the whole of the tract of country is thus

organised into one kingdom. Thus the history of England relates

how the kingdom of Wessex grew into predominance over the whole

of the country; that of France tells how the kings who ruled over

the Isle of France spread their rule over the rest of the land;

the history of Israel is mainly an account of how the tribe of

Judah obtained the hegemony of the rest of the tribes; and Roman

history, as its name implies, informs us how the inhabitants of

a single city grew to be the masters of the whole known world.

But their empire had been prepared for them by a long series of

similar expansions, which might be described as the successive

swallowing up of empire after empire, each becoming overgrown in

the process, till at last the series was concluded by the Romans

swallowing up the whole. It was this gradual spread of dominion

which, at each stage, increased men's knowledge of surrounding

nations, and it therefore comes within our province to roughly sum

up these stages, as part of the story of geographical discovery.

Regarded from the point of view of geography, this spread of man's

knowledge might be compared to the growth of a huge oyster-shell,

and, from that point of view, we have to take the north of the

Persian Gulf as the apex of the shell, and begin with the Babylonian

Empire. We first have the kingdom of Babylon--which, in the early

stages, might be best termed Chaldæa--in the south of Mesopotamia

(or the valley between the two rivers, Tigris and Euphrates), which,

during the third and second millennia before our era, spread along

the valley of the Tigris. But in the fourteenth century B.C., the

Assyrians to the north of it, though previously dependent upon

Babylon, conquered it, and, after various vicissitudes, established

themselves throughout the whole of Mesopotamia and much of the

surrounding lands. In 604 B.C. the capital of this great empire was

moved once more to Babylon, so that in the last stage, as well as in

the first, it may be called Babylonia. For purposes of distinction,

however, it will be as well to call these three successive stages

Chaldæa, Assyria, and Babylonia.

Meanwhile, immediately to the east, a somewhat similar process

had been gone through, though here the development was from north

to south, the Medes of the north developing a powerful empire in

the north of Persia, which ultimately fell into the hands of Cyrus

the Great in 546 B.C. He then proceeded to conquer the kingdom of

Lydia, in the northwest part of Asia Minor, which had previously

inherited the dominions of the Hittites. Finally he proceeded to

seize the empire of Babylonia, by his successful attack on the

capital, 538 B.C. He extended his rule nearly as far as India on

one side, and, as we know from the Bible, to the borders of Egypt

on the other. His son Cambyses even succeeded in adding Egypt for

a time to the Persian Empire. The oyster-shell of history had

accordingly expanded to include almost the whole of Western Asia.

The next two centuries are taken up in universal history by the

magnificent struggle of the Greeks against the Persian Empire--the

most decisive conflict in all history, for it determined whether

Europe or Asia should conquer the world. Hitherto the course of

conquest had been from east to west, and if Xerxes' invasion had

been successful, there is little doubt that the westward tendency

would have continued. But the larger the tract of country which an

empire covers--especially when different tribes and nations are

included in it--the weaker and less organised it becomes. Within

little more than a century of the death of Cyrus the Great the

Greeks discovered the vulnerable point in the Persian Empire, owing

to an expedition of ten thousand Greek mercenaries under Xenophon,

who had been engaged by Cyrus the younger in an attempt to capture

the Persian Empire from his brother. Cyrus was slain, 401 B.C., but

the ten thousand, under the leadership of Xenophon, were enabled,

to hold their own against all the attempts of the Persians to destroy

them, and found their way back to Greece.

Meanwhile the usual process had been going on in Greece by which a

country becomes consolidated. From time to time one of the tribes

into which that mountainous country was divided obtained supremacy

over the rest: at first the Athenians, owing to the prominent part

they had taken in repelling the Persians; then the Spartans, and

finally the Thebans. But on the northern frontiers a race of hardy

mountaineers, the Macedonians, had consolidated their power, and,

under Philip of Macedon, became masters of all Greece. Philip had

learned the lesson taught by the successful retreat of the ten

thousand, and, just before his death, was preparing to attack the

Great King (of Persia) with all the forces which his supremacy in

Greece put at his disposal. His son Alexander the Great carried

out Philip's intentions. Within twelve years (334-323 B.C.) he had

conquered Persia, Parthia, India (in the strict sense, _i.e._ the

valley of the Indus), and Egypt. After his death his huge empire

was divided up among his generals, but, except in the extreme east,

the whole of it was administered on Greek methods. A Greek-speaking

person could pass from one end to the other without difficulty, and

we can understand how a knowledge of the whole tract of country

between the Adriatic and the Indus could be obtained by Greek scholars.

Alexander founded a large number of cities, all bearing his name, at

various points of his itinerary; but of these the most important

was that at the mouth of the Nile, known to this day as Alexandria.

Here was the intellectual centre of the whole Hellenic world, and

accordingly it was here, as we have seen, that Eratosthenes first

wrote down in a systematic manner all the knowledge about the habitable

earth which had been gained mainly by Alexander's conquests.

Important as was the triumphant march of Alexander through Western

Asia, both in history and in geography, it cannot be said to have

added so very much to geographical knowledge, for Herodotus was

roughly acquainted with most of the country thus traversed, except

towards the east of Persia and the north-west of India. But the

itineraries of Alexander and his generals must have contributed

more exact knowledge of the distances between the various important

centres of population, and enabled Eratosthenes and his successors

to give them a definite position on their maps of the world. What

they chiefly learned from Alexander and his immediate successors

was a more accurate knowledge of North-West India. Even as late

as Strabo, the sole knowledge possessed at Alexandria of Indian

places was that given by Megasthenes, the ambassador to India in

the third century B.C.

Meanwhile, in the western portion of the civilised world a similar

process had gone on. In the Italian peninsula the usual struggle

had gone on between the various tribes inhabiting it. The fertile

plain of Lombardy was not in those days regarded as belonging to

Italy, but was known as Cisalpine Gaul. The south of Italy, as we

have seen, was mainly inhabited by Greek colonists, and was called

Great Greece. Between these tracts of country the Italian territory

was inhabited by three sets of federate tribes--the Etrurians,

the Samnites, and the Latins. During the 230 years between 510

B.C. and 280 B.C. Rome was occupied in obtaining the supremacy

among these three sets of tribes, and by the latter date may be

regarded as having consolidated Central Italy into an Italian

federation, centralised at Rome. At the latter date, the Greek

king Pyrrhus of Epirus, attempted to arouse the Greek colonies

in Southern Italy against the growing power of Rome; but his

interference only resulted in extending the Roman dominion down

to the heel and big toe of Italy.

If Rome was to advance farther, Sicily would be the next step,

and just at that moment Sicily was being threatened by the other

great power of the West--Carthage. Carthage was the most important

of the colonies founded by the Phoenicians (probably in the ninth

century B.C.), and pursued in the Western Mediterranean the policy

of establishing trading stations along the coast, which had

distinguished the Phoenicians from their first appearance in history.

They seized all the islands in that division of the sea, or at any

rate prevented any other nation from settling in Corsica, Sardinia,

and the Balearic Isles. In particular Carthage took possession

of the western part of Sicily, which had been settled by sister

Phoenician colonies. While Rome did everything in its power to

consolidate its conquests by admitting the other Italians to some

share in the central government, Carthage only regarded its foreign

possessions as so many openings for trade. In fact, it dealt with

the western littoral of the Mediterranean something like the East

India Company treated the coast of Hindostan: it established factories

at convenient spots. But just as the East India Company found it

necessary to conquer the neighbouring territory in order to secure

peaceful trade, so Carthage extended its conquests all down the

western coast of Africa and the south-east part of Spain, while Rome

was extending into Italy. To continue our conchological analogy, by

the time of the first Punic War Rome and Carthage had each expanded

into a shell, and between the two intervened the eastern section of

the island of Sicily. As the result of this, Rome became master

of Sicily, and then the final struggle took place with Hannibal in

the second Punic War, which resulted in Rome becoming possessed

of Spain and Carthage. By the year 200 B.C. Rome was practically

master of the Western Mediterranean, though it took another century

to consolidate its heritage from Carthage in Spain and Mauritania.

During that century--the second before our era--Rome also extended

its Italian boundaries to the Alps by the conquest of Cisalpine

Gaul, which, however, was considered outside Italy, from which it

was separated by the river Rubicon. In that same century the Romans

had begun to interfere in the affairs of Greece, which easily fell

into their hands, and thus prepared the way for their inheritance

of Alexander's empire.

This, in the main, was the work of the first century before our

era, when the expansion of Rome became practically concluded. This

was mainly the work of two men, Cæsar and Pompey. Following the

example of his uncle, Marius, Cæsar extended the Roman dominions

beyond the Alps to Gaul, Western Germany, and Britain; but from

our present standpoint it was Pompey who prepared the way for Rome

to carry on the succession of empire in the more civilised portions

of the world, and thereby merited his title of "Great." He pounded

up, as it were, the various states into which Asia Minor was divided,

and thus prepared the way for Roman dominion over Western Asia and

Egypt. By the time of Ptolemy the empire was thoroughly consolidated,

and his map and geographical notices are only tolerably accurate

within the confines of the empire.

[Illustration: EUROPE. Showing the principal Roman Roads.]

One of the means by which the Romans were enabled to consolidate

their dominion must be here shortly referred to. In order that

their legions might easily pass from one portion of this huge empire

to another, they built roads, generally in straight lines, and so

solidly constructed that in many places throughout Europe they

can be traced even to the present day, after the lapse of fifteen

hundred years. Owing to them, in a large measure, Rome was enabled

to preserve its empire intact for nearly five hundred years, and

even to this day one can trace a difference in the civilisation

of those countries over which Rome once ruled, except where the

devastating influence of Islam has passed like a sponge over the

old Roman provinces. Civilisation, or the art of living together

in society, is practically the result of Roman law, and this sense

all roads in history lead to Rome.

The work of Claudius Ptolemy sums up to us the knowledge that the

Romans had gained by their inheritance, on the western side, of

the Carthaginian empire, and, on the eastern, of the remains of

Alexander's empire, to which must be added the conquests of Cæsar

in North-West Europe. Cæsar is, indeed, the connecting link between

the two shells that had been growing throughout ancient history. He

added Gaul, Germany, and Britain to geographical knowledge, and,

by his struggle with Pompey, connected the Levant with his northerly

conquests. One result of his imperial work must be here referred

to. By bringing all civilised men under one rule, he prepared them

for the worship of one God. This was not without its influence on

travel and geographical discovery, for the great barrier between

mankind had always been the difference of religion, and Rome, by

breaking down the exclusiveness of local religions, and substituting

for them a general worship of the majesty of the Emperor, enabled

all the inhabitants of this vast empire to feel a certain communion

with one another, which ultimately, as we know, took on a religious

form.

The Roman Empire will henceforth form the centre from which to

regard any additions to geographical knowledge. As we shall see,

part of the knowledge acquired by the Romans was lost in the Dark

Ages succeeding the break-up of the empire; but for our purposes

this may be neglected and geographical discovery in the succeeding

chapters may be roughly taken to be additions and corrections of

the knowledge summed up by Claudius Ptolemy.
