[Illustration: DIORITE STATUE OF GUDEA, PATESI OF SHIRPURLA, REPRESENTED AS THE ARCHITECT OF THE TEMPLE OF GATUMDUG.--In the Louvre; Déc. en Chald., pl. 14.] In neither instance can it be said that the sculptor has completely succeeded in portraying a natural attitude, for the head in each case should be only in three-quarter profile, but such attempts at an unconventional treatment afford striking evidence of the originality which characterized the work of the Sumerians. Both the sculptures referred to date from the later Sumerian period, and, if they were the only instances recovered, it might be urged that the innovation should be traced to the influence of North Babylonian art under the patronage of the kings of Akkad. Fortunately, however, we possess an interesting example of the same class of treatment, which undoubtedly dates from a period anterior to the Semitic domination. This is afforded by a perforated plaque, somewhat similar to the more primitive ones of Ur-Ninâ,[24] engraved in shallow relief with a libation-scene. The figure of a man, completely nude and with shaven head and face, raises a libation-vase with a long spout, from which he is about to pour water into a vase holding two palm leaves and a flowering branch.[25] The goddess in whose honour the rite is being performed is seated in the mountains, represented as in later times by a number of small lozenges or half circles. While her feet and knees are in profile, the head is represented full-face, and the sculptor's want of skill in this novel treatment has led him to assign the head a size out of all proportion to the rest of the body. The effect is almost grotesque, but the work is of considerable interest as one of the earliest attempts on the part of the Sumerian sculptors to break away from the stiff and formal traditions of the archaic period. From the general style of the work the relief may probably be dated about the period of Eannatum's reign. [Illustration: Fig. 20.
