The parentage of Anubis himself is sometimes unclear. Some versions credit his father as Ra, while others state He was sired by Seth, the adversary of Horus and His Father, Osiris. The identity of Anubis' mother also varies from tale to tale and region to region. Some folklores tell that Anubis was born to Bastet, while others indicate it was instead Hesat. In versions involving Osiris as His Father, Anubis' mother is Nephthys; Wife and Sister of Seth.
