The Via Sebaste was the key to Roman control of Pisidia and its incorporation into the province of Galatia. It was completed in 6 BC by the Galatian governor Cornutus Arruntius Aquila. It was about 6 to 8 metres (20 to 26 ft) wide and capable of carrying wheeled traffic the whole way from Perga to Antioch. There are some surviving milestones.[1] According to Acts 13:14, the early Christian missionary Paul of Tarsus took the Via Sebaste from Perga to Antioch on his first missionary journey.[2] The road underwent major repairs twice in the Roman period. In the Byzantine or Ottoman period, it was narrowed to 3 to 3.5 metres (9.8 to 11.5 ft) and stepped over the mountains. It remained in use until the 19th century.[3]
