The Sumerian storm god was a goddess adopted by the Hebrews as, "Lilith," or in the original, "Li-Li-Tu." She was part of a cadre of evil sky spirits who could manifest themselves inside animals and humans and due to some ancient wrong were particularly found of killing or making suffer; men and male babies. She was considered a daytime goddess and her thundering storms gave her the epithet, "Rider on the clouds." She is related to the Greek Artemis(as a huntress), Phoenician Astarte, Ishtar, Hebrew Lilith, Sumerian Anatu, Egyptian Anit, Aryan Tiamat, the Hindu Devas and the prototype for ritual witchcraft. She was a completely evil character.

Tu is action, Ana is sky so her name represents the ACTIONS of the SKY!
