Pausanias (fl. c. 150 A.D.) was a Greek geographer and native of Lydia who explored Greece, Macedonia, Asia and Africa, and then settled in Rome. He may have lived the second half of the second century A.D. His travel writing, known as the Description of Greece is extant. It chiefly describes monuments from the Archaic and Classical periods.
