On the west bank of the Nile across the river from the tombs of Beni Hassan lie the ruins of the necropolis of Tuna el-Gebel, where thousands of sacred baboons (example below left) and ibises were buried in catacombs in the desert. The site is dedicated to Thoth, the divine scribe, usually depicted with a man's body and the head of an ibis, but also occasionally as a great white baboon. The catacombs are believed to have once stretched all the way nearby Ashmunein (Hermopolis) , but you may only visit a short section of rough-hewn corridors and blocked off side pasages. Above ground the Greco-Roman Tomb of Pestosiris (350 B.C.). is the finest of the several mausolea, and contains colourful scenes from the Book of the Dead. You will also visit the elaborate tomb of Isadora (below right).
