Thoth Winning Five Extra Days in a Game of Senet Against Khonsu
Ra cursed the goddess Nut so she could never give birth on any day of the year. Thoth, the god of wisdom, challenged the moon god Khonsu to a game of Senet to win a fraction of his light. Thoth won enough moonlight to create five extra days, allowing Nut to finally bear her five divine children.
