Corpses stripped naked by the victor on the battle-field are of more frequent occurrence; but these, being the bodies of despised and hated enemies, are treated in very summary fashion.[114] We may say the same of the prisoners whom they behead and flay alive.[115] The mutilated statue of a nude female, rather less than life, which bears a votive inscription of Assurbilkala, the son of Tiglath-Pileser, and is now in the British Museum, is a great rarity. It is believed to represent Istar. The execution is careful, but the forms are clumsy and the proportions bad; the bust is a great deal too short.[116] By his failure to appreciate living form for its own sake, for its beauty of line and harmony of proportion, the Mesopotamian sculptor put a voluntary limit to his ambition. He renounced, in advance, the only means within his reach of borrowing from the human figure the elements for a representation of the deity which should preserve a character of indefinite existence, of natural and sovereign excellence. But this abstention, or, if you like, this impotence, did not prevent Assyrian artists from fulfilling, in the most brilliant fashion, the other part of the task to which they were called by the habits and requirements of the society for which they laboured. The sculptors were mainly employed by the king; their chief business was to multiply his images; they were charged to commemorate the sovereign in every act of his life, in every one of the many parts involved by his indefatigable activity as builder, chief-justice, hunter, commander-in-chief, and supreme pontiff. From the king himself to the last of his soldiers or prisoners, every one who had his own marked place in a picture was draped; the sculptor could reproduce every episode of the royal life in the truest and most animated fashion, without ever having learnt to draw the nude. In fact, he was not called upon, like the Greek artist, to procure for the æsthetic sense the pure joys that are given by the sight of noble forms or movements well rendered; his duty was to commemorate by a series of clear and lively images those events that were celebrated in words in the text inscribed upon the very alabaster slabs beneath his hand. Assyrian sculpture had this documentary character in the very highest degree; its creations, in the intention of those by whom they were commissioned, were less works of art than records.[117] The long inscriptions and the endless series of pictures with which the palace walls were covered were no more than an illustrated book.
