Information on mermaids in cameos and other art. Mermaids are usually depicted as half human and half fish. They have been popular in many forms of art, including cameos, for many years.
Depictions of entities with the tails of fish, but upper bodies of human beings appear in Mesopotamian artwork from the Old Babylonian Period onwards. These figures are usually mermen, but mermaids do occasionally appear. The name for the mermaid figure may have been kuliltu, meaning “fish-woman”. Such figures were used in Neo-Assyrian art as protective figures and were shown in both monumental sculpture and in small, protective figurines.
The first known mermaid stories appeared in Assyria c. 1000 BC. The goddess Atargatis, mother of Assyrian queen Semiramis, loved a mortal (a shepherd) and unintentionally killed him. Ashamed, she jumped into a lake and took 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 — although the earliest representations of Atargatis showed her as a fish with a human head and arm, similar to the Babylonian god Ea. The Greeks recognized Atargatis under the name Derketo. Sometime before 546 BC, Milesian philosopher Anaximander postulated that mankind had sprung from an aquatic animal species. He thought that humans, who begin life with prolonged infancy, could not have survived otherwise.
