Ephesus was the capital city of its Asian province, and it continued to be an important trading centre during Roman rule, when the city had a population of roughly 250,000 people. Ephesus is now in Turkey, near the town of Selçuk.
The Library of Celsus was the third-largest library in the Roman world being only smaller than Alexandria and Pergamum. The Library is believed to have held around twelve thousand scrolls.
Celsus is buried in a crypt beneath the library in a marble sarcophagus.
