Mermaid?

he first known mermaid stories appeared in Assyria, ca. 1000 BC. The goddess Atargatis, mother of Assyrian queen Semiramis, loved a mortal shepherd and unintentionally killed him. Ashamed, she jumped into a lake to take the form of a fish, but the waters would not conceal her divine beauty. Thereafter, she took the form of a mermaid—human above the waist, fish below—though the earliest representations of Atargatis showed her as a fish with a human head and legs, similar to the Babylonian Ea. The Greeks recognized Atargatis under the name Derketo. Prior to 546 BC, the Milesian philosopherAnaximander proposed that mankind had sprung from an aquatic species of animal. He thought that humans, with their extended infancy, could not have survived otherwise.

A popular Greek legend turns Alexander the Great's sister, Thessalonike, into a mermaid after she died.^[1] She lived, it was said, in the Aegean and when she encountered a ship, she asked its sailors only one question: "Is King Alexander alive?" (Greek: "Ζει ο Βασιλιάς Αλέξανδρος;"), to which the correct answer was: "He lives and reigns and conquers the world" (Greek: "Ζει και βασιλεύει και τον κόσμο κυριεύει"). This answer pleased her so she calmed the waters and wished the ship farewell. Any other answer would spur her into a rage. She would raise a terrible storm, with certain doom for the ship and every sailor on board.^[2][3]

Lucian of Samosata in Syria (2nd century AD) in De Dea Syria ("Concerning the Syrian Goddess") wrote of the Syrian temples he had visited:

"Among them - Now that is the traditional story among them concerning the temple. But other men swear that Semiramis of Babylonia, whose deeds are many in Asia, also founded this site, and not for Hera Atargatis but for her own Mother, whose name was Derketo"

"I saw the likeness of Derketo in Phoenicia, a strange marvel. It is woman for half its length, but the other half, from thighs to feet, stretched out in a fish's tail. But the image in the Holy City is entirely a woman, and the grounds for their account are not very clear. They consider fishes to be sacred, and they never eat them; and though they eat all other fowls, they do not eat the dove, for she is holy so they believe. And these things are done, they believe, because of Derketo and Semiramis, the first because Derketo has the shape of a fish, and the other because ultimately Semiramis turned into a dove. Well, I may grant that the temple was a work of Semiramis perhaps; but that it belongs to Derketo I do not believe in any way. For among the Egyptians, some people do not eat fish, and that is not done to honor Derketo."^[4]
