Fairies and elves, and other half-human demons, are sometimes regarded as degenerate gods. It will be seen, however, that while certain spirits developed into deities, others remained something between these two classes of supernatural beings: they might attend upon gods and goddesses, or operate independently now against mankind and now against deities even. The "namtaru", for instance, was a spirit of fate, the son of Bel-Enlil and Eresh-ki-gal, queen of Hades. "Apparently", writes Professor Pinches, "he executed the instructions given him concerning the fate of men, and could also have power over certain of the gods."[103] To this middle class belong the evil gods who rebelled against the beneficent deities. According to Hebridean folk belief, the fallen angels are divided into three classes--the fairies, the "nimble men" (aurora borealis), and the "blue men of the Minch". In _Beowulf_ the "brood of Cain" includes "monsters and elves and sea-devils--giants also, who long time fought with God, for which he gave them their reward".[104] Similarly the Babylonian spirit groups are liable to division and subdivision. The various classes may be regarded as relics of the various stages of development from crude animism to sublime monotheism: in the fragmentary legends we trace the floating material from which great mythologies have been framed.

Among the gods of Babylonia none achieved wider and more enduring fame than Tammuz, who was loved by Ishtar, the amorous Queen of Heaven--the beautiful youth who died and was mourned for and came to life again. He does not figure by his popular name in any of the city pantheons, but from the earliest times of which we have knowledge until the passing of Babylonian civilization, he played a prominent part in the religious life of the people.
