Bast is sometimes said to be the mother of Anubis; (most likely a pun on the ointment jars that comprise her hieroglyphs -- the same jars that were used during the embalming process Anubis was lord of). She is also sometimes told to be his wife. Ra is also told to be the father of Bast, and the father of Anubis.
