“The date of the rise of the myth of Tammuz is uncertain, but as the name of this god is found on tablets of the time of Lugal-anda and Uru-ka-gina (about 3500 B.C.), it can hardly be of later date than 4000 B.C., and may be much earlier.
As he is repeatedly called “the shepherd,” and had a domain where he pastured his flock, Professor Sayce sees in Tammuz “Daonus or Daos, the shepherd of Pantibibla,” who, according to Berosus, ruled in Babylonia for 10 /sari/, or 36,000 years, and was the sixth king of the mythical period.
According to the classic story, the mother of Tammuz had unnatural intercourse with her own father, being urged thereto by Aphrodite whom she had offended, and who had decided thus to avenge herself.
Being pursued by her father, who wished to kill her for this crime, she prayed to the gods, and was turned into a tree, from whose trunk Adonis was afterwards born.
Aphrodite was so charmed with the infant that, placing him in a chest, she gave him into the care of Persephone, who, however, when she discovered what a treasure she had in her keeping, refused to part with him again.
Zeus was appealed to, and decided that for four months in the year Adonis should be left to himself, four should be spent with Aphrodite, and four with Persephone; or, as a variant account makes it, he should spend six months with Persephone, and six with Aphrodite on earth. He was afterwards slain, whilst hunting, by a wild boar.
Nothing has come down to us as yet concerning this legend except the incident of his dwelling in Hades, whither Ištar, the Babylonian Venus, went in search of him.
It is not by any means unlikely, however, that the whole story existed in Babylonia, and thence spread to Phœnicia, and afterwards to Greece. In Phœnicia it was adapted to the physical conditions of the country, and the place of Tammuz’s encounter with the boar was said to be the mountains of Lebanon, whilst the river named after him, Adonis (now the Nahr Ibrahim), which ran red with the earth washed down by the autumn rains, was said to be so coloured in consequence of being mingled with his blood.
The descent of Tammuz to the underworld, typified by the flowing down of the earth-laden waters of the rivers to the sea, was not only celebrated by the Phœnicians, but also by the Babylonians, who had at least two series of lamentations which were used on this occasion, and were probably the originals of those chanted by the Hebrew women in the time of Ezekiel (about 597 B.C.).”
