DEFINITION: A region in Panama where the type site of Sitio Conte has yielded deep rectangular tombs with grave goods of a rich ceramic and metallurgical tradition of c 500-1000 AD. The Coclé region was strongly influenced by the Quimbaya style. It is particularly known for its striking gold pieces set with precious stones, including emeralds, quartzes, jaspers, opals, agates, and green serpentines. The extremely fine polychrome pottery is characterized by decoration of intricate geometric patterns and by stylized biomorphic forms. Gold- and tumbaga-working techniques, probably imported from Columbia, include cire perdue casting. Some association with Tairona is recognized in some artifacts especially in the wing-shaped pendants. In addition to the grave goods, there are indications that wife and servant sacrifice took place at the death of an important person.QuimbayaCATEGORY: culture; artifact

DEFINITION: A coarse type of siliceous (silica) rock, a form of quartz, used for the manufacture of stone tools where flint was not available. It is of poorer quality than flint, formed from ancient ocean sediments and often has a semi-glassy finish. It is pinkish, white, brown, gray, or blue-gray in color. Flint, chert, and other siliceous rocks like obsidian are very hard, and produce a razor-sharp edge when properly flaked into tools. This crystalline form of the mineral silica is found as nodules in limestones. Varieties of chert are jasper, chalcedony, agate, flint, and novaculite. Chert and flint provided the main source of tools and weapons for Stone Age man.gem pointSYNONYMS OR RELATED TERMS: gempoint
