The metallurgy of the Chaldaeans, though indicative of a higher state of civilization and a greater knowledge of the useful arts than their stone weapons, is still of a somewhat rude character, and indicates a nation but just emerging out of an almost barbaric simplicity. Metal seems to be scarce, and not many kinds are found. There is no silver, zinc, or platinum; but only gold, copper, tin, lead, and iron. Gold is found in beads, ear-rings, and other ornaments, which are in some instances of a fashion that is not inelegant. [PLATE XVI., Fig. 3.] Copper occurs pure, but is more often hardened by means of an alloy of tin, whereby it becomes bronze, and is rendered suitable for implements and weapons. Lead is rare, occurring only in a very few specimens, as in one jar or bottle, and in what seems to be a portion of a pipe, brought by Mr. Loftus from Mugheir. [PLATE XVII., Fig. 1.] Iron, as already observed, is extremely uncommon; and when it occurs, is chiefly used for the rings and bangles which seem to have been among the favorite adornments of the people. Bronze is, however, even for these, the more common material. [PLATE XVII, Fig. 2.] It is sometimes wrought into thin and elegant shapes, tapering to a point at either extremity; sometimes the form into which it is cast is coarse and massive, resembling a solid bar twisted into a rude circle. For all ordinary purposes of utility it is the common metal used. A bronze or copper bowl is found in almost every tomb; bronze bolts remain in the pieces of marble used for tesselating; bronze rings sometimes strengthen the cones used for ornamenting walls; bronze weapons and instruments are, as we have seen, common, and in the same material have been found chains, nails, toe and finger rings, armlets, bracelets, and fish-hooks.
