carved on every side with life-sized figures of warriors or priests in feathered costumes, support beams of sapota wood, once carved, but now too decayed to permit of the designs being traced. There is no doubt that the building formed a temple. The religious nature of the Castillo must be indubitable to any one standing in front of it. Whether the bloody rites which are known to have been celebrated by Moctezuma's people in honour of Huitzopochtli, God of War, on the pyramids of Mexico had their equivalent on Chichen's mound is a very different matter. There is really no proof for or against. And if it were argued that the fact that there is no altar stone within, as is the case, goes far to prove that there were no such rites, there would be no value in such negative evidence. If bloody deeds in honour of a Sun-Deity were here enacted, possibly the flattened serpents' heads at the outer door, which would have been in view of the congregated thousands on the plains below, formed the butcher-blocks upon which the victim's palpitating heart, after his breast had been sliced open with the silex knife, was torn from its tissues to be burned as an offering to the god in the inner Holy of Holies; while the body, scarcely lifeless, was pitched (as some writers who value the picturesque rather than the accurate would like us to believe) down the steps to be sacramentally eaten by the worshippers. On the other three sides of the building runs a corridor 6 feet wide, three doors with sculptured jambs facing almost due south, east, and west. A woodland path, in places wide enough to merit the title of road, and here and there showing signs of an ancient cementing, leads from this grimly majestic shrine of fallen gods to perhaps the grimmest pool in the world. Yucatan is peculiar in being riverless and lakeless. Rivers and lakes there are, but these are all subterranean, generally from fifty to two hundred feet beneath the surface. But dotted over the Peninsula are deep holes or water-caves, reservoirs carved by nature out of the limestone and fed by these underground sources. For these the Mayan Indian name is "cenote," and they are often huge. Two of the largest are at Chichen. Indeed the very name is due to them; for "_chi_" is "mouth" and "_chen_" is "wells." Thus _Chichen_ was the city at the "mouth of the wells."
