Hannu wrote of his expedition in stone. Under Sankhare (Mentuhotep III), whose name occurs as the 58th on the Table of Abydus, lived a functionary named Hannu, who records on a rock-inscription, in this same valley of Hammamat, some particulars of Mentuhotep's reign, from which it appears that the kings of this dynasty had dealings with Arabia; and the trade thus introduced directly by the valley route from Coptos to the Red Sea, seems to have revived the fallen fortunes of the old monarchy.[2]
