Nut - To the ancient Egyptians she was the personification of the sky (originally she was a goddess of just the sky at day, where the clouds formed) and the heavens. She was believed to be the daughter of the gods Shu and Tefnut, the granddaughter of the sun god Ra. Her husband was also her brother, Geb. She was thought to be the mother of five children on the five extra days of the Egyptian calendar, won by Thoth - Osiris who was born on the first day, Horus the Elder on the second, Set on the third, Isis on the fourth, and Nephthys the last born on the fifth day. The days on which these deities were born were known as the five days of the years, and they were celebrated all over Egypt.
