Anubis  

From The Art and Popular Culture Encyclopedia

However, as lesser of the two gods of the underworld, he gradually became considered the son of Osiris, but Osiris' wife, Isis, was not considered his mother, since she too inappropriately was associated with life. Instead, his mother became considered to be Nephthys, who had become strongly associated with funerary practice, indeed had in some ways become the personification of mourning, and was said to supply bandages to the deceased. Subsequently, this apparent infidelity of Osiris was explained in myth, in which it was said that a sexually frustrated Nephthys had disguised herself as Isis in order to appeal to her husband, Set, but he did not notice her as he was infertile. However, Isis' husband Osiris mistook Nephthys for his wife, which resulted in Anubis' birth. Other versions of the myth depict Set as the father, and it remains unclear as to whether Set was truly infertile or not.
