Discovery of The Book of the Dead upon the walls of the chamber pyramid at Saqqara near Cairo by Karl Richard Lepsius.
Original drawings made from the German 1842 Lepsius expedition to the Fayoum and Egypt. Lepsius maps out the Hawara pyramid and the surrounding landscape in detail, discovering the lost labyrinth of Hawara as a U-shaped enclosure facing the pyramid of Amenemhet III.
A diary written in English by an unknown traveller is dated 1842, believed to have been written by a member of the Lepsius party, or to have known of the Lepsius excavations. The traveller writes two journals, one left behind in Cairo, the other turning up many years later.
