The ideal mother & wife, Isis was patroness of nature & magic; friend of slaves, sinners, artisans, & the downtrodden; protector of the dead & goddess of children. She listened to the prayers of the wealthy, maidens, aristocrats, & rulers. She married her brother Osiris, & conceived Horus with him. Isis was instrumental in the resurrection of Osiris when he was murdered by Set. It was believed that the Nile River flooded every year because of the tears of sorrow which Isis wept for Osiris.
