Historical Notes:
Seleucia in the region of Pisidia in Anatolia was named after and possibly also founded by the Diadoch Seleukos I Nikator (305-281 BC).  Under Roman Imperial rule, the city came to be known as Claudio-Seleucia, as indicated by the legends on its provincial coinage, after its restoration by Emperor Claudius.
