<human>:  Why is the book called ‘The Book of the Dead’?
<bot>: That would be the Egyptian Book of the Dead. The ancient Egyptians believed that after death, the soul would travel through the Duat, a vast underworld, and into the realm of the dead. In order to cross the Duat, the soul needed to make its way through the underworld by crossing the river of the heart. The ancient Egyptians believed that the soul needed to be protected by various protective amulets, called the Book of the Dead.
