Thus it was only in 1859, that Lord Dufferin and his assistants, Dr. Lorange and Cyril C. Graham, started to excavate the southwest corner of the hypostyle hall of Mentuhotep's temple. Clearing the immense mass of debris, they soon discovered the plundered grave of Queen Tem, one of Mentuhotep's wives. Realising the potential of the site, they then gradually worked their way to the sanctuary, where they found the granite altar of Mentuhotep with a representation of Amun-Re and various other finds such as the grave of Neferu TT319. Finally, in 1898, Howard Carter discovered the Bab el-Hosan cache in the front court, where he uncovered the famous black seated statue of the king.
