I. The Isaurians escaped notice for long centuries. They first come to mention in an episode of the year 322 B.C. when Perdiccas after subduing Cappadocia captured their city, described as strong and populous, of ancient opulence. Isaurians next emerge in the campaign that earned a triumphal cognomen for P. Servilius Vatia (cos. 79), the proconsul of Cilicia.As the name of a region, Isauria was destined to acquire a wide extension. Early in the reign of Antoninus Pius it was applied to Cilicia Tracheia, as one of the three portions (with Pedias and Lycaonia) in the enlarged Cilician province. Before that, sundry problems infest the definition of Isauria. One of them that continues to perplex is conveyed by a passage in Pliny. After Cilicia and before proceeding to deal in summary fashion with Pisidae and Lycaonia, he inserts remarks about the “gens Isaurica” and the adjacent people called Homanades.
