In ancient cultures the character, or mythological creature, from which Lilith seems to be derived was a night visitor, female demon, serpent, child thief or in modern language a succubus. She is mentioned by name only once in the Bible in different ways depending on the ancient copy of Isaiah you consult. Then, in the late first millennium Jewish scholars noting the creation of woman from clay in Genesis chapter one and Adam's rib in chapter two attributed the first reference to Lilith and the second to Eve.
