In the early 4th century, all Cilicia was detached by order of Diocletian for administrative purposes from the northern slope of Taurus, and we find a province called at first Isauria-Lycaonia, and later Isauria alone, extending up to the limits of Galatia, but not passing Taurus on the south. Pisidia, part of which had hitherto been included in one province with Isauria, was also detached, and made to include Iconium; Isauria received the eastern part of Pamphylia. The coastal Metropolis of Seleucia was designated as Isauria's provincial capital.
