The historic legends of several members of the family have been well preserved. According to the earliest authorities, those of the Quiches went back more than eight hundred years before the conquest,[202] that is, to about 700 A. D.; while the chronicles of the Mayas seem to present a meagre sketch of the nation nearly to the beginning of the Christian era.[203] The uniform assertion of these legends is that the ancestors of the stock came from a more northern latitude, following down the shore of the Gulf of Mexico. This is also supported by the position of the Huastecas, who may be regarded as one of their tribes left behind in the general migration, and by the tradition of the Nahuas which assigned them a northern origin.[204] So far no relationship has been detected with any northern stock, but the striking similarity of some art remains in the middle Mississippi to those of Yucatan, suggests that one should search in this vicinity for their priscan home.[205] Physically the Mayas are short, strong, dark, and brachycephalic. The custom of compressing the skull antero-posteriorly which formerly prevailed, exaggerated this latter peculiarity. When first encountered by the Spaniards they were split into a number of independent states of which eighteen are enumerated in Yucatan alone. According to tradition, these were the fragments of a powerful confederacy which had broken up about a century before, the capital of which was Mayapan. The tribes were divided into gentes, usually named after animals, with descent in the male line. A man bore the names of both his father’s and mother’s gens, but the former was distinguished as his “true name.” The chieftainship was hereditary, a council from the gentes deliberating with the ruler. The art in which these people excelled was that of architecture. They were born builders from a remote epoch. At the time of the conquest the stately structures of Copan, Palenque, T’Ho, and many other cities were deserted and covered with an apparently primitive forest; but others not inferior to them Uxmal, Chichen Itza, Peten, etc., were the centers of dense population, proving that the builders of both were identical. The material was usually a hard limestone, which was polished and carved, and imbedded in a firm mortar. Such was also the character of the edifices of the Quiches and Cakchiquels of Guatemala. In view of the fact that none of these masons knew the plumb-line or the square, the accuracy of the adjustments is remarkable.[206] Their efforts at sculpture were equally bold. They did not hesitate to attempt statues in the round of life-size and larger, and the facades of the edifices were covered with extensive and intricate designs cut in high relief upon the stones. All this was accomplished without the use of metal tools, as they did not have even the bronze chisels familiar to the Aztecs. Gold, silver and copper were confined to ornaments, bells and similar purposes.
