Adapted from http://de.wikipedia.org/wiki/Grab_des_Mentuhotep
The tomb of Mentuhotep was found in Thebes in al-Asasif in 1823 at the transition to Dra Abu el-Naga during excavations by the Italian Giuseppe Passalacqua. The grave was found uncovered and is extremely well documented at the time, since Giuseppe Passalacqua was on site to find the grave. [... He] arranged for drawings to be made on the site. The finds later came to the Egyptian Museum Berlin and were published in detail by Georg Steindorff.
