An ancient Greek inscription and the Library of Celsus in Ephesus. Ephesus was an ancient Greek city in the region known as Ionia during the Classical period. It lies beside Selcuk and Kusadasi in Asia Minor (Anatolia), Turkey. The Library of Celsus was built in the 2nd century AD to serve as a burial monument dedicated to Tiberius Julius Celsus Polemaeanus, the Roman senator and proconsul of Asia. The style of the library, with its ornate, balanced, well-planned facade, reflects the Greek influence on Roman architecture.
