Other buildings in Babylonia of a more secular character have been preserved in a more satisfactory state than those specifically dedicated to the gods, but the royal palaces themselves have for the most part undergone such a course of reconstruction that it is very difficult to determine the precise form which the original building assumed. Ur-Ninâ has bequeathed to us the remains of an elaborate building which he erected at his royal city Lagash, but it appears to be a storehouse rather than an integral part of a palace; Ur-bau and Gudea some centuries later have also left unmistakable signs of their building activity at this famous city of the past. In the course of the excavation of a large palace in one of the ruined mounds of Tellô, many bricks inscribed with the name of Gudea were found, and this discovery not unnaturally led to the hasty conclusion that this elaborate building so wonderfully preserved, was actually the royal residence of this long deceased ruler, but a closer investigation revealed the presence of other bricks bearing the name of one, Hadadnadinakhe, in both Greek and Aramæan characters, thereby proving conclusively that the building in question belonged to the Parthian period and could not be assigned to a date earlier than the latter half of the second century B.C. The bricks belonging to Gudea’s early building had been re-used as material for this later structure, a practice to which recourse was frequently had in Mesopotamia. Parts however of Gudea’s early building were actually incorporated in the Parthian palace, the best preserved of which are a gateway (cf. Pl. V) and a portion of a tower, while underneath one corner of the palace, part of a wall erected by Ur-bau, one of Gudea’s immediate predecessors, was discovered.
