Lilith is a character from Jewish mythology, and like most mythological creatures the legends surrounding her are confusing and even contradictory. She is alternatively Adam’s first wife, a lustful female demon or the wife of Samael. She is barely mentioned in the Old Testament but she features more prominently in the Zohar and other Kabbalistic works. In the Kabbalah she is a type of succubus who is responsible for nocturnal emissions and is associated with the Qlippoth. The one thing that all sources agree on however is that Lilith is supremely beautiful and deadly dangerous.
The above representation by the English Pre-Raphaelite John Collier follows the tradition of having Lilith enjoying the sensuous en-coiling of her naked body by a snake, presumably the same snake that would tempt Adam’s second wife Eve. Unlike Eve though, Lilith actively embraces the independence offered by the emissary of evil.
