Both men and women were fond of jewelry, and adorned themselves with rings, bracelets, ear-rings, and necklaces. The women also wore anklets, like many of the Oriental women of to-day. The men carried a stick in the street, and all who could afford it had a small engraved cylinder of stone attached to the wrist by a ring which passed through an orifice in the cylinder. The cylinder served the purpose of a seal, and was constantly required in business transactions. No deed was valid without the seal or mark of the contracting parties; when either of them was too poor to possess a seal, a nail-mark was impressed upon the clay of the contract tablet, and a note added stating to whom it was that the mark belonged. The seal-cylinder was a Babylonian invention. In a land where there were no stones every pebble was of value, and the Babylonians accordingly became expert gem-cutters at a very early period. Gem-cutting, in fact, was a highly developed art among them, and the seal-cylinder of Ibni-sarru, the librarian of Sargon of Akkad, which is now in a private collection in Paris, is one of the most beautiful specimens of the art that has ever been produced. The pebble was cut in a cylindrical shape, and various figures were engraved upon it. The favorite design was that of a god or goddess to whom the owner of the seal is being introduced by a priest; sometimes the King takes the place of the deity, at other times it is the adventures of Gilgames, the hero of the great Chaldean Epic, that are represented upon the stone. The design is usually accompanied by a few lines of inscription, giving the name of the owner of the seal, as well as that of his father, and stating of what god or King he was “the servant.” The seals were often kept in stock by their makers, a blank space being left for the inscription, which was to be engraved upon them as soon as they had found a purchaser. Hence it is that at times the names have never been filled in. The style and pattern of the cylinder changed in the course of centuries, as well as the favorite materials of which it was made. Under the dynasty of Ur, which preceded that of Khammurabi, for instance, hæmatite was more especially in vogue; in the age of Nebuchadnezzar crystal became fashionable. At one period, moreover, or among the artists of a particular local school, the representation of a human sacrifice was common. Between the inscription on the cylinder, however, and the subjects engraved upon it there is seldom, if ever, any connection, except when a portrait is given of the god or King of whom the owner calls himself the servant.
