|Pauly: 150-141 BC
Diegylis was king of the tribe of the Caeni who dwelled on the coast of
the Propontis near the city of Cypsela. He was infamous for his cruelty
and ruthlessness. During the conflict between his son-in-law Prussias
of Bythinia and Attalos of Pergamene, brother of Eumenes II, he seized
and destroyed the city of Lysimacheia 144 BC. Attalos sent an army
under the thracian Straton who defeated Diegylis 145 BC. When Prussias
lost control over his kingdom he asked Diegylis for help. His
father-in-law provided a body guard of 500 men.
Contrary to Diegylis, Attalos treated his captives with humanity and mildness. This caused the Caeni to revolt and murder their ruler.
No coins were struck in the name of Diegylis.
