Gongylos, from Eretria in Euboea, was a 5th-century BCE Greek statesman who served as an intermediary between the Spartans and Xerxes I of the Achaemenid Empire, and was a supporter of the latter.
Likely portrait of one of the Gongylid rulers, from a 5th century coin of Pergamon.
Possible coinage of Gongylos, with Apollo on the obverse, and Gongylos wearing the Persian cap on the reverse, as ruler of Pergamon for the Achaemenid Empire. Pergamon, Mysia, circa 450 BCE. The name of the city ΠΕΡΓ ("PERG"), appears for the first time on this coinage, the first evidence for the name of the city.
Pergamon or Pergamum, also referred to by its modern Greek form Pergamos (Πέργαμος), was a rich and powerful ancient Greek city in Mysia. It is located 26 kilometres (16 mi) from the modern coastline of the Aegean Sea on a promontory on the north side of the river Caicus and northwest of the modern city of Bergama, Turkey.
