Of the Yucatec sites the most important is that of Chichen Itza. The remains here are considerable, though they conform to no definite plan save that the same arrangement of building round rectangular courts prevails. The buildings themselves are typically Maya, though structurally they exhibit a certain advance upon those of the central area, and Maya glyphs are found throughout, with certain important exceptions. Of the peculiarities which distinguish the architecture of Yucatan from that of the last region, many have already been mentioned, including the mosaic ornament with which the façades of buildings are decorated. But another important feature remains to be recorded. Throughout the whole of Yucatan only two dates in the long count have been discovered, and one of these is at Chichen Itza. The site is interesting as providing evidence of more than one stage of construction. One of the finest buildings, the so-called Monjas, shows plainly that a considerable addition was made to the foundation at a time later than the original building (Fig. 83). At the same period an additional storey was added, and one of the chambers in the earlier structure was filled solid with masonry to support the weight. Certain annexes were also built (Pl. XXIX, 2; p. 350), in the decoration of which ornamental fragments from the façades of previous “palaces” were included, but the inscriptions are in regular Maya characters, though no date in the long count is included. Other buildings in the immediate neighbourhood are in similar style and belong presumably to the same epoch. But further north is a large group of structures of an entirely different character of ornamentation. These include the famous ball-court and attached temples (Pl. XXVIII; p. 348), the Castillo (also seen in Pl. XXVIII), a large structure of which only the numerous square sculptured columns remain, and the so-called “Temple of the Tables.” On these buildings neither Maya glyphs nor mosaic masks are found, while the Castillo and upper ball-court temple are furnished with serpent-columns similar to those of Tulan. In the lower temple attached to the ball-court is an elaborate relief showing figures, exhibiting no signs of cranial deformation, armed with spears and spear-throwers, assisting, so it would seem, at the obsequies of some personage in the centre who is distinguished by a huge feathered snake which overshadows him. Many of the figures are accompanied by glyphs which are distinctly Nahua in type, while their ornaments and dress combine both Nahua and Maya characters; further, a sun-disc in Nahua style occurs at the top of the relief. In the Castillo are atlantean figures carved in relief in similar style, and in the Temple of the Tables were found a number of slabs supported by small caryatides (Fig. 84), carved in the round, exactly similar to some which have been found at Tlaxcala. Finally, several stone recumbent figures supporting vases, of the type shown on Pl. VIII, 2; p.
