Everywhere, too, the history of these heroes is that of a struggle against
some potent enemy, some dark demon or dragon, but as often against some
member of their own household, a brother or a father.

The identification of the Light-God with the deity of the winds is also
seen in Aryan mythology. Hermes, to the Greek, was the inventor of the
alphabet, music, the cultivation of the olive, weights and measures, and
such humane arts. He was also the messenger of the gods, in other words,
the breezes, the winds, the air in motion. His name Hermes, Hermeias, is
but a transliteration of the Sanscrit Sarameyas, under which he appears in
the Vedic songs, as the son of Sarama, the Dawn. Even his character as the
master thief and patron saint of the light-fingered gentry, drawn from the
way the winds and breezes penetrate every crack and cranny of the house,
is absolutely repeated in the Mexican hero-god Quetzalcoatl, who was also
the patron of thieves. I might carry the comparison yet further, for as
Sarameyas is derived from the root _sar_, to creep, whence _serpo_,
serpent, the creeper, so the name Quetzalcoatl can be accurately
translated, "the wonderful serpent." In name, history and functions the
parallelism is maintained throughout.

Or we can find another familiar myth, partly Aryan, partly Semitic, where
many of the same outlines present themselves. The Argive Thebans
attributed the founding of their city and state to Cadmus. He collected
their ancestors into a community, gave them laws, invented the alphabet of
sixteen letters, taught them the art of smelting metals, established
oracles, and introduced the Dyonisiac worship, or that of the reproductive
principle. He subsequently left them and lived for a time with other
nations, and at last did not die, but was changed into a dragon and
carried by Zeus to Elysion.
