In the typical form of her myth, Isis was the first daughter of Geb, god of the Earth, and Nut, goddess of the Sky, and she was born on the fourth intercalary day. She married her brother, Osiris, and she conceived Horus with him. Isis was instrumental in the resurrection of Osiris when he was murdered by Set. Using her magical skills, she restored his body to life after having gathered the body parts that had been strewn about the earth by Set.
