At Wadi Hammamat a rock inscription dates back to the 12th dynasty. It lists five cartouche names: "Khufu, Djedefra, Khafra, Baufra" and "Djedefhor". Because all royal names are written inside cartouches, it was often believed that Baufra and Djedefhor once had ruled for short time, but contemporary sources entitle them as mere princes. Khufu's attendance roll call in this list might indicate that he and his followers were worshipped as patron saints. This theory is promoted by findings such as alabaster vessels with Khufu's name found at Koptos, the pilgrimage destination of Wadi Hammamat travellers.
