Iztac Mixcoatl was, indeed, the Chichimec Adam, the father of the tribe. A hymn to the gods of the hunt, of whom Mixcoatl was the chief, is as follows:
Song of the Cloud-serpents
I
Out of the seven Caverns he sprung (was born).
II
Out of the land of the prickly plant he sprung.
III
I came down (was born)
I came down
With my spear made of the prickly plant
I came down
I came down
With my spear of the prickly plant.
