Damascus, Bab (Gate) of Kaysan

Bab (Gate) Kaysan (under the Romans the Gate of Saturn). According to the New Testament, this would the place where St. Paul escaped Damascus as related in KJV 2 Corinthians 11.32-33:

32 In Damascus the governor under Aretas the king kept the city of the Damascenes with a garrison, desirous to apprehend me: 33 and through a window in a basket was I let down by the wall, and escaped his hands.

The Bibilical text raises a controversy about the legal status of the City of Damascus at the time, was it ruled by the Romans or the Nabateans (Aretas was a Nabatean ethnarch) and, if the latter, what was the nature of the retationship between the two powers? Also disputed is the exact location of St. Paul's departure from the city. Be that as it may, the Chapel of Saint Paul claims the honor of Paul's descent. It is constructed from the remains of an Arab gateway (that succeeded that of the Romans) blocked under the Ottomans. The Greek Catholics turned those remains into a chapel in the 1920-30's. The Australian historian Ross Burns raises doubts that such a closely guarded spot would be a likely choice for a clandestine getaway.
