The museum is described in Bancroft, iv. 554; in Mayer’s _Mexico as it was_, etc., and his _Mexico, Aztec, etc._; Fossey’s _Mexique_. On Le Plongeon’s discovery of the Chac-mool see _Amer. Antiq. Soc. Proc._, Apr., 1877; Oct., 1878, and new series, i. 280; Nadaillac, Eng. tr., 346; Short, 400; Le Plongeon’s _Sacred Mysteries_, 88, and his paper in the _Amer. Geog. Soc. Journal_, ix. 142 (1877). Hamy calls it the Toltec god Tlaloc, the rain-god; and Charnay agrees with him, giving (pp. 366-7) cuts of his and of the one found at Tlaxcala.] The ancient Anahuac corresponds mainly to the valley of Mexico city.[1016] Bancroft (iv. 497) shows in a summary way the extent of our knowledge of the scant archæological remains within this central area.[1017] In the city of Mexico not a single relic of the architecture of the earlier peoples remains,[1018] though a few movable sculptured objects are preserved.[1019] * * * * * [Illustration: OLD MEXICAN BRIDGE NEAR TEZCUCO. After a sketch in Tylor’s _Anahuac_, who thinks it the original _Puente de las Bergantinas_, where Cortes had his brigantines launched. The span is about 20 feet, and this Tylor thinks “an immense span for such a construction.” Cf. H. H. Bancroft, _Native Races_, iv. 479, 528. Bandelier (_Peabody Mus. Reports_, ii. 696) doubts its antiquity.] Tezcuco, on the other side of the lake from Mexico, affords some traces of the ante-Conquest architecture, but has revealed no such interesting movable relics as have been found in the capital city.[1020] Twenty-five miles north of Mexico are the ruins of Teotihuacan, which have been abundantly described by early writers and modern explorers. Bancroft (iv. 530) makes up his summary mainly from a Mexican official account, Ramon Almaraz’s _Memoria de los trabajos ejecutados por la comision cientifica de Pachuca_ (Mexico, 1865), adding what was needed to fill out details from Clavigero, Humboldt, and the later writers.[1021] Bancroft (iv. ch. 10), in describing what is known of the remains in the northern parts of Mexico, gives a summary of what has been written regarding the most famous of these ruins, Quemada in Zacatecas.[1022] [Illustration: THE INDIO TRISTE. After a photograph in Bandelier’s _Archæological Tour_, p. 68. He thinks it was intended to be a bearer of a torch, and has no symbolical meaning.]
