The ancient Greeks feared similar creatures, notably Lamia, a demoness with the head and torso of a woman and the lower body of a snake. In one version of the legend, Lamia was one of Zeus' mortal lovers. Filled with anger and jealousy, Zeus' wife, the goddess Hera, made Lamia insane so she would eat all her children. Once Lamia realized what she had done, she became so angry that she turned into an immortal monster, sucking the blood from young children out of jealousy for their mothers.
