Early siren-mermaids

Some surviving Classical period examples had already depicted the siren as mermaid-like. The sirens are depicted as mermaids or "tritonesses" in examples dating to the 3rd century BC, including an earthenware bowl found in Athens and a terracotta oil lamp possibly from the Roman period.

The first known literary attestation of siren as a "mermaid" appeared in the Anglo-Latin catalogue Liber Monstrorum (early 8th century AD), where it says that sirens were "sea-girls... with the body of a maiden, but have scaly fishes' tails".
