Nut - The Goddess of the sky
Nut was the god of the sky and the heavens. She was the mother of the five gods born on the "epagomenal" days. Ra had become annoyed because Geb and Nut were locked in a perpetual embrace so he asked Shu to separate them. He also decreed that Nut should not bear children on any day in the calendar, but Thoth won the five "epagomenal" days days from the moon and Nut had five children: Osiris, who was born on the first day, Horus , Set , Isis , and Nephthys the last born on the fifth day. These days were a time of celebration all over Egypt.
Geb - The God of Earth
In ancient Egypt Geb was the god of the earth. He also supported Horus' right to the throne following the death of Osiris. As the Egyptians believed that the pharaohs were the living images of Horus, the pharaohs were sometimes known as the "Heir of Geb". During the Ptolemaic period, Geb became identified with the Greek god of time, Kronos.
