Dascylium, Dascyleium, or Daskyleion (Ancient Greek: Δασκύλιον, Δασκυλεῖον), also known as Dascylus,[1] was a town in Anatolia some 30 kilometres (19 mi) inland from the coast of the Propontis, at modern Ergili, Turkey.
[2] After the Conquests of Cyrus the Great in 547 BC, Dascylium was chosen as the seat of the Persian satrapy of Hellespontine Phrygia,[3] comprising lands of the Troad, Mysia and Bithynia.
[4] Pharnabazus was satrap of Darius III there, until Alexander the Great appointed Calas, who was replaced by Arrhidaeus in the Treaty of Triparadisus.
[6] When Alexander of Macedon invaded Asia in 334 BC, the first of the major battles by which he overthrew the Achaemenid Empire was fought at the Granicus river on his way to Dascylium from Abydos on the coast.
[10] In August 2021, archaeologists led by Kaan Iren have announced the discovery of Ancient relief described Greek-Persian wars at Dascylium.
