1. The parents of Isis are Geb (the earth god) and Nuet (the sky goddess). She is one of four quadruplets: Isis, Osiris, Nephthys, and Set (Seth). She and her twin (quadruplet) brother Osiris were so much in love that they made love to each other while still in their mother’s womb.
2. Set killed his brother Osiris and cut his body into pieces. Isis found the pieces and put them back together. Flapping her wings above Osiris'
corpse, she wailed in mourning. She restored life to Osiris (briefly) by flapping her wings and filling his mouth and nose with air. Just before Osiris went into the underworld (and took on the form of a falcon-headed being), he made love to Isis, and the result of their union was Horus.
