Lilith has two faces: that of the stealer (and devourer) of babies, and the seducer of men. The former is a myth that arises for women, the other is how this energy interacts with man. This is focusing on the latter. Originally, Lilith was not one but a fairly terrifying legion of Sumerian and even pre-Sumerian desert/air demons that eventually got codified into this new form, especially by the Jews.
There's a fair amount of Jungian analysis on the symbol in "Lilith the First Eve" by Siegmund Hurwitz.
All that said, I've always had a thing for red heads. So it's been a naturally appealing image for me to explore.
