the fourth, rain after which nothing matured or dried. Thus Tlaloc combined two aspects, a beneficent and a terrible; and this is not unnatural, for rain in Mexico is more often than not accompanied by thunder, and the fertilizer is therefore also the smiter. As the god of fertility maize belonged to him, though not altogether by right, for according to one legend he stole it after it had been discovered by other gods concealed in the heart of a mountain. The great importance of Tlaloc and the Tlaloque in the worship of the Ancient Mexicans may be gathered from the fact that no less than five of the twenty month-festivals were dedicated to them, and that Tlaloc shared with Uitzilopochtli the great pyramid at Tenochtitlan. The most important of the Tlaloque was Opochtli, a fishing and hunting god, the inventor of nets and the bird-spear. Closely connected with Tlaloc was his wife Chalchiuhtlicue (Pl.

The most important festivals to these deities took place on mountain-tops, for it is there that the rain-clouds gather before they sweep over the plain, and closely associated with them was the worship of mountains represented by small figures called Tepictoton, with hair dressed in two horns, whose sacrificial victims were similarly adorned.

In connection with her worship we are first brought into contact with a strange and gruesome rite, peculiar to this part of America, and performed exclusively in honour of agricultural deities. The victim was flayed, and the priest
