Biblioteca de Celso // Library of Celsus

The library of Celsus is an ancient Roman building in Ephesus, Anatolia, now part of Selçuk, Turkey. It was built in honor of the Roman Senator Tiberius Julius Celsus Polemaeanus (completed in 135 AD) by Celsus’ son, Gaius Julius Aquila (consul, 110 AD). Celsus had been consul in 92 AD, governor of Asia in 115 AD, and a wealthy and popular local citizen. He was a native of nearby Sardis and amongst the earliest men of purely Greek origin to become a consul in the Roman Empire and is honored both as a Greek and a Roman on the library itself. Celsus paid for the construction of the library with his own personal wealth.

The library was built to store 12,000 scrolls and to serve as a monumental tomb for Celsus. Celsus is buried in a sarcophagus beneath the library, in the main entrance which is both a crypt containing his sarcophagus and a sepulchral monument to him. It was unusual to be buried within a library or even within city limits, so this was a special honor for Celsus.

Ephesus (English pronunciation: /ˈɛfəsəs/); Ancient Greek Ἔφεσος, Ephesos; Turkish Efes) was an ancient Greek city, and later a major Roman city, on the west coast of Asia Minor, near present-day Selçuk, Izmir Province, Turkey. It was one of the twelve cities of the Ionian League during the Classical Greek era. In the Roman period, Ephesus had a population of more than 250,000 in the 1st century BC, which also made it one of the largest cities in the Mediterranean world.

The city was famed for the Temple of Artemis (completed around 550 BC), one of the Seven Wonders of the Ancient World. Emperor Constantine I rebuilt much of the city and erected new public baths. Following the Edict of Thessalonica from emperor Theodosius I, the temple was destroyed in 401 AD by a mob led by St. John Chrysostom. The town was partially destroyed by an earthquake in 614 AD. The city's importance as a commercial center declined as the harbor was slowly silted up by the Cayster River (Küçük Menderes).

Ephesus was one of the seven churches of Asia that are cited in the Book of Revelation. The Gospel of John may have been written here. The city was the site of several 5th century Christian Councils, see Council of Ephesus. It is also the site of a large gladiators' graveyard.

Turkey (Turkish: Türkiye), known officially as the Republic of Turkey ( Türkiye Cumhuriyeti (help·info)), is a Eurasian country located in Western Asia (mostly in the Anatolian peninsula) and in East Thrace in Southeastern Europe. Turkey is bordered by eight countries: Bulgaria to the northwest; Greece to the west; Georgia to the northeast; Armenia, Azerbaijan (the exclave of Nakhchivan) and Iran to the east; and Iraq and Syria to the southeast. The Mediterranean Sea and Cyprus are to the south; the Aegean Sea is to the west; and the Black Sea is to the north. The Sea of Marmara, the Bosphorus and the Dardanelles (which together form the Turkish Straits) demarcate the boundary between East Thrace and Anatolia; they also separate Europe and Asia.
