Among stelae and other monuments of historical value of this period may be mentioned: Stele from the tomb of =Khnemu-ḥetep= at Beni-Hasan (Vestibule, No. =182=); statue of =Ȧmenemḥāt=, a veritable royal kinsman,[33] and =master= of =the robes= (Bay 1, No. =183=); seated figure of =Ȧmeni=, inscribed with a prayer for offerings (Bay 1, No. =184=); stele of =Nekhtȧ=, a Ḥā Prince (Bay 1, No. =185=); stele of =Ȧnḥer-nekht=, =chief clerk= of =grain supply= (Bay 1, No. =186=); stele of =Ȧntef=, an overseer of priests (Bay 1, No. =187=); stele of =Sa-Ȧnḥer=, a deputy keeper of the seal, with figures of eighteen of his children and relatives bearing offerings (Bay 1, No. =189=); stele of the lady =Khu=, with figures of her two husbands and twelve children (Bay 1, No. =190=); stele set up to =the memory= of =sixteen persons= and their mothers (Bay 2, No. =191=); stele of =Sebek-āāiu=, with hieroglyphics inlaid with blue paste (Bay 2, No. =193=); stele of =Ȧmeni=, of unusual style (Bay 2, No. =194=); stele of =Erṭā-Ȧntef-Ṭāṭāu=, a governor of the Sûdân (Bay 4, No. =196=); and stele of =Ȧntef=, with an inscription of twenty lines in which the deceased describes his virtues and abilities (Bay 7, No. =197=). As examples of the wall-paintings on the tombs of this period may be mentioned the slabs from the tomb of =Teḥuti-ḥetep=, a high official who flourished during the reign of Ȧmenemḥāt II (Bay 2, Nos. =198-200=; Bay 7, No. =201=). To the same period, or a little later, belongs the sandstone =obelisk= which was set up to the memory of an Egyptian official of the copper mines at Ṣarâbît al-Khâdim in the Peninsula of Sinai (Bay 1, No. =202=). The other monuments of the XIIth dynasty consist of =altars=, or =tablets for offerings=, of which a considerable number are exhibited in =Bays 14, 16, and 17=. Among the altars of the XIIth dynasty may be noted that of the Ḥā prince =Usertsen=, a superintendent of the prophets, sculptured with figures of vases and two tanks, and inscribed with an address to the living (Bay 17, No. =269=). The altar is a rectangular, flat slab of stone, with a projection which was intended to serve as a spout, from which the drink offerings were supposed to run off into a vessel placed to receive them. In the altar small rectangular tanks were sometimes cut, but usually the surface was sculptured with figures of haunches of meat, bread-cakes, fruit, flowers, unguent vases, libation jars, etc., and on the edges and sides were inscribed prayers for funerary offerings of meat and drink and for things which were deemed necessary for the dead. The Egyptians believed that the material things placed on such altars possessed, like animated creatures, two bodies and spirits; their bodies were consumed by the priests and others, and their spirits by the gods. Some believed in the transmutation of offerings.
