The myth went around the 13th century AD. Until then, Lilith was not enough of a threat to fear him, she could even become an image of liberation and equality for women.
Sudden death syndrome “crib death” appeared in which healthy newborns woke up dead. The mothers asked the rabbis for an explanation and comfort, and they blamed Lilith, justifying that God could not be so cruel and that only someone who had separated from Him would be capable of something like that. This pain, turned into hate, has sentenced her.
The story of Lamashtu was known, a Mesopotamian demon who killed children at night and attacked men seducing them. The union of the two stories completed the myth, women hated Lilith with her beauty, courage and seduction and her freedom was threatened.
Today, feminists of the 20th century take Lilith as their flag, both for the aspect of the original goddess of humanity and for the freedom of choice over patriarchy.
