Colonia Caesarea was the oldest and the chief among the Pisidian coloniae which were founded by Augustus. The emperor briefly refers in the Monumentum Ancyranum to one or more colonies in Pisidia; but the reference is so slight as to give no evidence of their number or of the time or circumstances of foundation : it only shows that he planted in Pisidia at least one colony of soldiers. Strictly these garrison cities were ’Pisidian,’ not ‘in Pisidia’: they were founded on the Pisidian frontier of the empire, but the Romans expressed themselves with geographical looseness, and the looseness had a political meaning and purpose : Rome did not trouble herself about barbarian geography, but intended to substitute a Roman geography and classification.
