Tammuz, Attys, Hadad, Adonis, Gingras, & Artemis, Istar, Aphrodite, Semiramis, Gingira
“Greek mythology itself knew the name of Tammuz as well as that of Adonis. Theias or Thoas was not only the Lemnian husband of Myrina and the king of the Tauric Khersonese who immolated strangers on the altars of Artemis, he was also king of Assyria and father of Adonis and his sister Myrrha or Smyrna.
In the Kyprian myth the name of Theias is transformed into Kinyras; but, like Theias, he is the father of Adonis by his daughter Myrrha. Myrrha is the invention of a popular etymology; the true form of the name was Smyrna or Myrina, a name famous in the legendary annals of Asia Minor.
Myrina or Smyrna, it was said, was an Amazonian queen, and her name is connected with the four cities of the western coast–Smyrna, Kymê, Myrina and Ephesos–whose foundation was ascribed to Amazonian heroines.
But the Amazons were really the warrior priestesses of the great Asiatic goddess, whom the Greeks called the Artemis of Ephesos, and who was in origin the Istar of Babylonia modified a little by Hittite influence.

It was she who, in the Asianic cult of Attys or Hadad, took the place of Istar and Aphroditê; for just as Attys himself was Tammuz, so the goddess with whom he was associated was Istar. At Hierapolis, which succeeded to the religious fame and beliefs of the ancient Hittite city of Carchemish, the name under which the goddess went seems to have been Semiramis, and it is possible that Semiramis and Smyrna are but varying forms of the same word.
However this may be, in the Kyprian Kinyras who takes the place of Theias we have a play upon the Phoenician kinnór, or “either,” which is said to have been used in the worship of Adonis. But its real origin seems to be indicated by the name of Gingras which Adonis himself bore. Here it is difficult not to recognize the old Accadian equivalent of Istar, Gingira or Gingiri, “the creatress.”
The fact that Tammuz was the son of Ea points unmistakably to the source both of his name and of his worship. He must have been the primitive Sun-god of Eridu, standing in the same relation to Ea, the god of Eridu, that Adar stood to Mul-lil, the god of Nipur.

It is even possible that the boar whose tusk proved fatal to Adonis may originally have been Adar himself. Adar, as we have seen, was called the “lord of the swine” in the Accadian period, and the Semitic abhorrence of the animal may have used it to symbolise the ancient rivalry between the Sun-god of Nipur and the Sun-god of Eridu.
Those who would see in the Cain and Abel of Scripture the representatives of elemental deities, and who follow Dr. Oppert in explaining the name of Abel by the Babylonian ablu, “the son,” slightly transformed by a popular etymology, may be inclined to make them the Adar and Tammuz of Chaldean faith.”
