With the coming of Julius Caesar to Britain in the middle of the first century before the birth of Christ, we reach the time in the history of our country when definite facts about its people begin to be recorded. Thus we know from Caesar’s own writings that the Britons lived in houses like those of the Gauls, that they had great numbers of cattle, that they used copper coins, that many of the inland tribes did not grow corn but lived on milk and flesh and went clothed in skins, that in war time they dyed their bodies with a blue stain to give them a more terrible aspect, and that they wore long hair on their heads and their upper lips. So also, with regard to their religion, Caesar tells us that their priests were called Druids; that if any crime had been committed, or if there were any dispute about an inheritance or a boundary, it was the Druids who gave judgment; that they had vast stores of learning, all of which was committed to memory and none committed to writing; and that their chief doctrine was that the soul of man did not perish, but passed after death into another body, so that no man should fear death. [Illustration: BRONZE CELT OR AXE HEAD FOUND AT SWINE. ] From these accounts we see that there had been great progress made since the times described in the last chapter. This was due to the migration westwards of a new race of people—the Kelts—who had gained a knowledge of the use of metal, and who, consequently, had weapons and implements made of bronze instead of stone. Their greater knowledge gave them greater power, and the extinction of the men of the Stone Age was only a question of time. For not often was the bronze-weaponed warrior slain by a weapon of stone. But the account written by Julius Caesar refers to the inhabitants of the southern parts of our island. ‘Many of the inland tribes do not grow corn, but live on milk and flesh and go clothed in skins.’ This passage may be taken as true of the tribes living north of the Humber, known—so later Roman writers tell us—as the BRIGANTES, the wildest and most savage of the tribes inhabiting Britain. Let us see what Mr. Mortimer’s discoveries have to tell us of these BRIGANTES. The most interesting discovery, perhaps, was that made in a barrow on Calais Wold, the highest point of the Yorkshire Wolds, 807 feet above sea-level. Here, on the mound being removed, a double row of stake-holes was exposed in the surface of the ground. These were from 3 to 15 inches in diameter, and were arranged in circles having diameters of 21½ and 28 feet. Outside these were four other stake-holes, and beyond these again a circular trench 100 feet in diameter, 3 feet 9 inches deep, 9 feet across at the top, and 1 foot across at the bottom. Within the double circle of stake-holes was a cavity cut in the chalk and containing a skeleton lying on its side, with its knees bent.
