The opening as it read in 2005

Decapolis ( Greek : deka , ten; polis , city) was a group of ten cities on the eastern frontier of the Roman Empire in Syria and Palestine .1 The ten cities were not an official league or political unit, but they were grouped together because of their language, culture, location, and political status. The Decapolis cities were centers of Greek and Roman culture in a region that was otherwise Semitic ( Jewish , Nabatean , and Aramean ).2 With the exception of Damascus, the "Region of the Decapolis" was located in modern-day northeastern Israel , northwestern Jordan , and southwestern Syria. Each city had a certain degree of autonomy and self-rule.3
