I wonder if this sign says, NO BALLOONS are allowed in the library. Thank you.
Celsus Library at Ephesus, in Turkey. The library was built around 117 A.D., and it was the third largest library after the libraries in Alexandra (Egypt) and Pergamum (Turkey).
"The library, which may have contained in excess of 10,000 scrolls, also had lecture rooms where visiting officials, sophists, poets, performers and other interested citizens could met, and it became an important cultural center and a meeting place for discussion and philosophical debate."
