SILVERSMITHS' AND GOLDSMITHS' WORK. Per sonal ornaments, utensils, vases, decorative objects, etc., made of silver or gold, with their various alloys, are generally known as silversmiths' and goldsmiths' work. The article that follows is treated historically under the following divisions: Egyptian to Roman, with Jewellery included in a separate section; European; North and South America; Oriental Work. (See also EGYPT : Art and Archaeology; INDIAN AND SINHALESE ART AND ARCHAEOLOGY; ROMAN ART; BYZANTINE ART; BRONZE; IRON IN ART ; DRINKING VESSELS ; JEWELLERY.) Gold, silver and their natural or artificial mixture called electrum m. white gold, were worked in ancient Greece and Italy for per sonal ornaments, for vessels, arrows and weapons, for coinage, and for inlaid and plated decoration of baser metals. Pliny notes that gold is generally found mixed with silver, and says that when the proportion of silver amounted to one-fifth the alloy was called electrum. The source of native electrum was the river Pactolus in Lydia, whose golden sands supplied the fabulous wealth of Croesus. Aegean lands were rich in precious metals. The consid erable deposits of treasure found in the earliest prehistoric strata on the site of Troy are generally assigned to the second city ; they tre earlier than the sixth ("Homeric") city, and are not likely to be later than 2000 B.C. The largest of them, the so-called Treasure of Priam, is a representative collection of jewels and plate. The gold ornaments were packed in a large silver cup. They consist of elaborate diadems or pectorals, six bracelets, 6o earrings or hair-rings, and nearly 9,00o beads. The Trojan vases have bold and simple forms, mostly without ornament, but some are lightly fluted. Many are wrought from single sheets of metal. The char acteristic handle is a heavy rolled loop soldered or rivetted to the body. Some silver flasks with inverted cup-covers have small shoulder-studs pierced vertically for hanging. Bases are some times round or pointed, sometimes fitted with separate collars, but more often slightly cupped to make a low ring-foot. An odd shape in gold is an oval bowl or cup with a broad lip at each end and two large roll-handles in the middle. The oval body has Sumerian affinities, and it seems likely that Trojan arts at this time were Asiatic rather than European. Asiatic influence had in deed invaded Europe, for the oval shape occurs in the contempo rary pottery of the Greek mainland and islands (Helladic and Cycladic). A plain spouted bowl of usual early Helladic shape in the Louvre is the typical specimen of goldsmith's work from pre Mycenaean Greece, and the scarcity of precious metals points to lack of wealth as prime cause of the artistic backwardness of these regions. Silver seems to have been more plentiful in the Cyclades, but only a few simple vessels, head-bands, pins and rings survive. Conditions were different in Crete.
