The theatre dated from Greek times, but was changed considerably in Roman times, when it could hold 15.000 spectators. A tunnel ran under it for 60 meters, so the cities east-west avenue could go on unhindered. The same notice indicates St. Thecla suffered torments here. From an internet (New Advent) encyclopaedia: “The reputed pupil of the Apostle Paul, who is the heroine of the apocryphal "Acta Pauli et Theclae". Our knowledge of her is derived exclusively from these Acts, which appeared about 180. According to this narrative Thecla was a virgin of Iconium who was converted to Christianity and led to dedicate herself to perpetual virginity by the preaching of the Apostle Paul. Miraculously saved from death at the stake to which she had been condemned, she went with St. Paul to Antioch in Pisidia where she was thrown to the wild beasts and was again saved from death by a miracle.”
