BRONZE.

_Bells._--Bells seem to have been in pretty general use by the more

cultured American races previous to the conquest. The form best known is

the hawk bell, or common sleighbell of the North. The globular body is

suspended by a loop at the top and is slit on the under side, so that

the tinkling of the small free pellets of metal may be audible. Such

bells are found in considerable numbers in the graves of Chiriqui,

although I have no positive assurance that any of the examples in my

possession were actually taken from graves which contained typical

Chiriquian relics of other classes. The specimens now in the National

Museum (Fig. 41) are in most cases, if not in all, of bronze, as

determined by Mr. R. B. Riggs, of the chemical laboratory of the United

States Geological Survey. All have been cast in molds. In most cases

there are traces of a plating of gold. The largest is 1¼ inches in

height and three-fourths of an inch in diameter. It is surmounted by the

rude figure of an animal, through or beneath the body of which is an

opening for the attachment of a cord. Others have simple loops at the

top. The small perforated specimen belongs to Mr. Stearns. The

additional piece given in Fig. 42 is unique in conception. It represents

a human head, which takes an inverted position when the bell is

suspended. The lower part of the bell forms a conical crown to the head

and the ring of suspension is attached to the chin. Double coils of wire

take the place of the ears, and the other features are formed by setting

on bits of the material used in modeling. This specimen belongs to the

collection of Mr. Stearns. Many examples of more elaborate workmanship

have been recovered from the tombs and are now to be found in the

collections of America and Europe.

A specimen found many years ago on the Rio Grande, near Panama, and

figured in Harper's Weekly, was of gold and showed specific variations

from the Chiriquian pieces. It will be seen by reference to the outline

given in Fig. 43 that three very neatly shaped and gracefully ornamented

bells are mounted upon a circular plate to which a short handle is

attached. It was evidently not intended for suspension, but rather to be

held in the hand as a rattle.

A question as to the authenticity of these bells as aboriginal works

very naturally arises, and it may be difficult to show to the

satisfaction of the skeptical mind that any particular specimen is not

of European origin or inspiration. At the same time we are not without

strong evidences that such bells were in use by the Americans before the

advent of the whites. Historical accounts are not wanting, but I shall

only stop to point out some of the internal evidences of the native art.

The strongest argument is to be found in the presence of analogous

features in other branches of the art and in other arts. The eyes of the

golden figures of reptiles are in many cases minute hawk bells, and in

works of clay, the purely aboriginal character of which has not been

called in question, similar features are discovered. The American origin

of the bell, therefore, is not to be questioned. The form originated, no

doubt, in the rattle, at first a nutshell or a gourd; later it was

modeled in clay, and in time the same idea was worked out in the legs

and the ornaments of vessels and in the heads and other parts of animal

forms, which were made hollow and supplied with tinkling pellets. With

the acknowledged skill of these people in the working of metals, there

is no reason why the bells described should not have been manufactured

independently of European aid and influence, provided the requisite

metal was at hand.

Grande.]

It should be observed that if these early American bells were copied

from or based upon Spanish originals they would not probably vary

greatly in type with the various sections from which they are recovered,

but it is observed that marked and persistent differences do occur. The

well known Mexican bell, an example of which is outlined in Fig. 44,

although of bronze, is generically distinct in form and construction.

In a brief review I may recall the more salient points regarding the use

of metals in ancient Chiriqui. Gold, silver, copper, and apparently tin

are represented.

Gold and copper were very plentifully distributed among the isthmian

races, but we have little information as to the sources of supply. Free

gold is found in the stream beds of many localities, and copper was

probably found in its native state in some convenient locality; yet it

is not impossible that these metals were transported from distant

regions, as the inhabitants of Chiriqui must have had considerable

intercourse with those of Central America on the north and with those of

Granada on the south. Silver and tin are found in alloys with gold and

copper, but not as independent metals. The silver gold alloy is probably

a natural compound. In no case have I found silver to exceed 6 per cent.

of the composite metal. Tin was artificially alloyed with copper,

forming bronze. The latter metal resembles our ordinary bronze in color

and hardness, but I am unable to secure more than a qualitative analysis

on account of the scarcity of specimens available for the purpose. We

have no information in regard to the origin of the tin. It is not found

in a native state, and since it seems hardly probable that the

Chiriquians understood smelting ores we are left in doubt as to whether

it was obtained from more cultured nations to the north or to the south

or from transoceanic countries.

The gold-copper alloys appear to range between pure gold and pure

copper. If the bronze is of European origin, then we must conclude that

all objects made of that metal are of post-Columbian manufacture. This

question will probably be definitely settled in the near future.

The greater number of the objects were formed by casting in molds.

Hammering was but little practiced, excepting, apparently, in the

formation of sheet gold, which was probably an indigenous product.

Repoussé work is not found, save as represented in the crimping and

indenting of gold leaf. Engraving and carving were not practiced. It may

be considered certain that gilding, or at least plating, was understood.

The objects are obtained from ancient graves of which no record or

reliable tradition is preserved. They are all ornaments, no coin,

weapon, tool, or utensil having come to my notice. The absence of

utensils and of hammered objects of any kind strikes me as being rather

extraordinary, since it is popularly supposed that, in the normal

succession of events, hammering should precede casting and that utensils

should be made before elaborate ornaments.

The work exhibits close analogies with that of the mainland of South

America, but these analogies appear to be in material, treatment, and

scope of employment rather than in the subject matter of the

conceptions. The personages and zoömorphic characters represented are

characteristically Chiriquian, and were derived no doubt from the

mythology of the locality. These works affiliate with the various works

in stone and clay, the art products of the province thus constituting a

fairly homogeneous whole and being entirely free from traces of European

influence.

Metals do not come into use early in the history of a race, as they are

not found in shapes or conditions suitable for immediate use, nor are

they sufficiently showy when found to be especially desirable for

ornaments. A long period must have elapsed before the use of metals was

discovered, and a longer period must have passed before they were

worked; and, in the light of our knowledge of the ancient tribes of the

United States, it would seem that a considerable degree of culture may

be achieved before the casting of metals is understood; but in the

ordinary course of progress the discovery of methods of alloying rare

metals would be far separated from that of the simple fusing and casting

of a single metal, such as gold. The Chiriquian peoples not only had a

knowledge of the methods of alloying gold with copper, and, apparently,

copper with tin, but, if our data are correct, they were able to plate

the baser metals and alloys with sheet gold, and, what is far more

wonderful, to wash them with gold, producing an effect identical with

that of our galvanic processes.

The character of the conceptions embodied in the art unite with

evidences of technical skill to prove to us that American culture, as

represented by the metal ornaments of Chiriqui, was not the product of a

day, but of long periods of experiment and progress.
