I was visiting the historic city of Nicaea (Iznik) in Turkey this August and studied it's history. I noticed the entrance gate at the southern wall of the city which was built by the Romans.
The same entrance gate was used by the Ottoman sultan Orhan 1 (Orhan Gazi) when he entered the city after a long siege in 1331ad. The lower part of the gate has paintings of the sultan and his army celebrating the historic victory and event. The photos are attached.
There is a Greek inscription in large type at the top. Could someone who knows Greek translate this for me?
