What is "satala"

Located in Turkey, the settlement of Satala ( Satał), according to the ancient geographers, was situated in a valley surrounded by mountains, a little north of the Euphrates, where the road from Trapezus to Samosata crossed the boundary of the Roman Empire, when it was a bishopric, which remains a Latin Catholic titular see. Later it was connected with Nicopolis by two highways. Satala is now Sadak, a village of 500 inhabitants, in the Kelkit district of Gümüşhane Province in Turkey.
