Cave Book. Nut goddess of the sky, called 'The Mysterious', with a ram-headed sun god and a sun disc in her palms. On the left side a scarab pushes a sun disc, followed by a ram, a disc, a ram-headed dia and a child. On the right side a series of crocodiles push a ram's head, a scarab, a wadjet eye and a solar disc. Both sides feature two snakes with human heads and posthuman beards. This is a representation of the solar cycle.
