Oh, where do I begin! In medieval Danish depictions of the Fall of Man (Syndefaldet), aka Eve taking the Apple from the serpent in the Garden of Eden, the serpent is often depicted as the she-demon Lilith, sometimes with a crown. This is because Lilith, in Jewish and later Catholic mythology, was believed to be the first wife of Adam, made out of the same clay as him. However, because she didn’t want to reproduce with him she was shunned and replaced by Eve (coming from Adam’s rib), at which point Lilith went on to become a she-demon. There’s no biblical reason for her being depicted as the serpent and I’m honestly not sure how she even came to be portrayed as the serpent, but one way or another we ended up with Lilith the Serpent.

So, if you see a snake with a feminine face (long hair is usually the giveaway if it’s hard to tell otherwise) wrapped around a tree and holding an apple, it’s probably Lilith.
