Protective amulets taking the shape of gods, animals or various symbols were often placed in tombs. In Ancient Egypt, gold was the colour of divinity. Taweret was the goddess of maternity and childbirth, who protected women and children. She was depicted as a combination of a hippopotamus, a crocodile and a lion, all of these animals were fierce when protecting their young. Amulets of Taweret were popular, used by expectant mothers. In the Book of the Dead, Taweret was also seen as a goddess who guided the dead into the afterlife. Many of the deities relating to birth also appear in the undeworld to help with the rebirth of the souls into their life after death.
