Archaeology is the recovery and study of the material objects of past civilizations for the purpose of reconstructing these civilizations to study them more fully. Archaeologists put these objects in their proper period and use them to explain the ways of ancient life. Modern archaeology began with Heinrich Schliemann and his discovery of Troy. Dr. Young shows a reconstruction of a farm in ancient Greece and the ruins of a temple at Sounion. At Dura-Europos in Syria, remains of three religions were found, a Christian chapel, a Jewish synagogue, and a temple of the cult of Mithras. Students of archaeology must study the languages and history of the civilizations they are studying along with the technical aspects of archaeology.
