Certain metallurgists, however, maintain that a Bronze Age, properly so called, may never have existed; and that iron may have been manufactured during and even before the period to which the bronze tools that are exhibited in museums belong. Iron was undoubtedly known to the Egyptians at a very remote date, perhaps as early as bronze.[484] Primitive methods of extracting iron from its ore, which are still practised in India and Africa, require far less skill than the manufacture of bronze: the metallurgists argue that since iron is rapidly oxidized by air and moisture, the iron tools which they assume to have been made in the so-called Bronze Age must have perished in the conditions to which most of the bronze tools that have been discovered were exposed; and they insist that iron tools have actually been found in association with objects of the early Bronze and even of the late Neolithic Age.[485]
The inconsistency of these arguments is self-evident; and if their authors had known the rudiments of archaeology, they would never have published them.[486] Hundreds of iron weapons have been recovered from the Thames: a competent archaeologist has affirmed that there was not one which could not with certainty be attributed to some period later than the Bronze Age; and since numerous articles of stone and bronze have been found in the same bed, he reasonably concludes that if iron implements had been used in the Bronze Age, some few at least must have come to light.[487] Nor is there any reason to suppose that if iron tools had been laid in graves of the Bronze Age, they would necessarily have perished beyond recognition; for in the famous Tyrolese cemetery of Hallstatt, and in many other deposits that, like it, belonged to the transitional period when bronze and iron were simultaneously used, the iron objects, oxidized though they are, retain their distinctive forms.[488] Yet in the numerous British barrows of the Bronze Age, and in the hoards of the same period that have been unearthed in England, Scotland, and Wales, not a trace of iron has ever been found.[489] Nothing then can be more certain than that in Britain, as in the rest of Europe, the Iron Age was preceded by a long period during which the only metals used were copper and bronze.[490]
Where did the European bronze culture originate?
Every antiquary knows that bronze did not reach this country until long after it was first used in Southern Europe, and that it was common in Egypt many centuries before; but in what part of the world it was first manufactured remains an unsettled question.[491] The oldest piece of bronze that has yet been dated was found at Mêdûm in Egypt, and is supposed to have been cast about three thousand seven hundred years before the birth of Christ. But the metal may have been worked even earlier in other lands; for a bronze statuette and a bronze vase, which were made twenty-five centuries before our era, have been obtained from Mesopotamia; and the craft must have passed through many stages before such objects could have been produced. Yet it would be rash to infer that either the Babylonians or the Egyptians invented bronze; for neither in Egypt nor in Babylonia is there any tin. Some archaeologist who shall explore the virgin fields of the Far East may one day be able to prove that bronze was worked by the Chinese, in whose country both copper and tin abound, earlier than by any other people; but even so it will still remain doubtful whether the art was not independently discovered elsewhere. There is no evidence that the bronze culture of Mexico and Peru did not originate in America;[492] and although it was once believed that all the tribes of Europe ultimately derived their knowledge of the metal from Asia,[493] there are many who now maintain that it is impossible to detect in European deposits of the Bronze Age the slightest trace of Oriental origin.[494]
Origin and affinities of the bronze culture of Britain.
But whatever may have been the case in Southern lands, there is no doubt that the knowledge of bronze came to this country from abroad. The old theory that it was a result of Phoenician commerce with Britain has long been abandoned;[495] and British bronze implements are so different from those of Norway and Sweden, Denmark, and Hungary that it cannot have been derived from any of those countries.[496] German influence was felt at a comparatively late period;[497] but from first to last the British bronze culture was closely connected with that of Gaul, and through Gaul with that of Italy.[498]
Period of its commencement.
The period when bronze first appeared in Britain can only be approximately fixed. It is certain that in the south-eastern districts iron tools began to be used not later than the fourth century before the Christian era.[499] The final period of the British Bronze Age is marked by the discovery of bronze-founders’ hoards, all of which contain tools or fragments of tools which are known as socketed celts, or other socketed instruments which were contemporary with them. These hoards are so numerous and so widely diffused, and the objects of which they are composed are so varied in form, that the time during which they were deposited cannot, in the opinion of experts, have been less than four or five hundred years. But before the first socketed celt was cast the bronze culture passed through earlier stages, during which the flat celts that resembled those of stone were being used, and then gradually giving way to improved forms, which in their turn were succeeded by later developments. The veteran archaeologist who has handled and examined almost every specimen of these numerous varieties has arrived at the conclusion that the British Bronze Age must have begun at the latest between 1400 and 1200 B.C.;[500] and while no one would now contend for a later date, there are some who maintain that bronze was first used in Britain twenty centuries before the Christian era.[501]
Physical characters of the late neolithic and early bronze-using invaders of Britain.
After the Bronze Age set in, as before the close of the preceding period, bands of invaders, wholly different in physical type from the neolithic aborigines, landed successively through long ages upon our eastern and southern shores. They came from the Netherlands, from Denmark and its islands, perhaps also from Scandinavia and from Gaul. They must not, however, be identified either with the invaders who introduced the Celtic language into Gaul or with any Celtic-speaking people. There is no evidence, and it is in the last degree improbable, that any Celtic tribe had appeared in Gaul at the time when the alien immigrants began to settle in Britain, or that Celtic had then taken shape as a branch of the Indo-European language. Those immigrants have often been described as a tall, stalwart, round-headed race; but the evidence of sepulchral remains shows that they sprang from various stocks. Those of the type which is commonly regarded as specially characteristic of the Bronze Age were taller and much more powerfully built than the aborigines: their skulls were comparatively short and round; they had massive jaws, strongly marked features, enormously prominent brow ridges and retreating foreheads; and their countenances must have been stern, forbidding, and sometimes almost brutal. Similar skulls, which have much in common with the primitive Neanderthal type,[502] have been exhumed from neolithic tombs in Denmark and the Danish island of Falster. But the skeletons which have been found in some of the oldest Scottish cists belonged to men whose average height, although they were sturdy and thickset, was barely five feet three inches, and whose skulls, shorter and rounder than the others, as well as their milder features, proved that they were an offshoot of the so-called Alpine race of Central Europe, of which there were numerous representatives in Gaul. Again there were tall men with skulls of an intermediate type; while others, who combined harsh features and projecting brows with narrow heads, and whose stature was often great, would seem to have been the offspring of intermarriage between the older and the newer inhabitants. Not a single skeleton of the characteristic British round-barrow type is known to have been discovered on French soil: the round-headed inhabitants of Gaul were as conspicuously short as those of Britain were generally tall; nor, excluding the Britons of the Alpine stock, was there any physical resemblance between the two peoples. The British invaders of the Alpine stock, judging from the pottery which was found with their skeletons, came for the most part, as we shall afterwards see, not from Gaul but from the valley of the Rhine. Moreover, the round-headed people of Gaul settled there first early in the Neolithic Age, before a Celtic word was spoken; and although their descendants formed the substratum of the Gallic population who, in Caesar’s time, called themselves Celts, that name was introduced by conquerors of a wholly different stock. Probably a Celtic invasion of Britain took place before the British Iron Age began: but the remains of such invaders are not recognizable in any British graves.[503]
