Of Narâm-Sin's successors upon the throne of Akkad we know little. The name of Bin-Gani-sharri, one of his sons, has been recovered upon a seal,[78] and on a seal-impression from Tello,[79] but his name has not been found with the royal title, so that we do not know whether he succeeded his father upon the throne. Another son of Narâm-Sin, the reading of whose name is uncertain, held the post of patesi of Tutu, for his name and title have been preserved on a perforated plaque from Tello, engraved by Lipush-Iau, who describes herself as his daughter and lyre-player to the Moon-god, Sin.[80] The famous seal of Kalki, the scribe, who was in the service of Ubil-Ishtar, "the king's brother," is also to be assigned to this period, but to which reign we cannot tell. The scene engraved upon the seal[81] gives an interesting picture of one of these early Semitic princes attended by his suite. The central figure, who carries an axe over his left shoulder, is probably Ubil-Ishtar, and he is followed by a Sumerian servant, whom we may identify with the scribe Kalki, the holder of the seal. The other attendants, consisting of the prince's huntsman, his steward with his staff of office, and a soldier, are all bearded Semites. The shaven head and fringed garment of the Sumerians are here retained by the scribe, suggesting that, though the Sumerians were employed by their conquerors, little racial amalgamation had taken place.
