The scientific study of material evidence, such as burials, architecture, tools, and pottery remaining from past cultures ? primarily but not exclusively those of Stone Age and ancient period. Its principal activities include preliminary field surveys, excavation, and the classification, dating, and interpretation of finds. Towards the end of the nineteenth century archaeology became an academic study, making increasing use of scientific techniques and systematic methods. Archaeologists are the people who are trained in making field expeditions to uncover materials in ruins, deserts, jungles, and so on. They locate, excavate, catalog, analyze, and conserve their finds, many of which are displayed in museums.Also see Aegean art, American Indian art, Chinese art, civilization, Cycladic art, Egyptian art, Etruscan art, excavate, Greek art, interdisciplinary, Japanese art, Meroitic art, Pre-Columbian art, Roman art, science and art, and tradition.
