Year 317 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Brutus and Barbula (or, less frequently, year 437 Ab urbe condita). The denomination 317 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Macedonian Empire

• Battle of Byzantium: At the start of the year, Antigonus Monophthalmus sends Nicanor with a large fleet to do battle with Cleitus the White at the Hellespont. The two fleets meet in near Byzantium, Cleitus wins a victory in which some 70 ships of Nicanor are captured, sunk or disabled, the remnant excaping to Chalcedon, where they are joined by Antigonus and his army. Antigonus orders the remaining 60 ships to be readied for renewed action, and assigns his strongest and most loyal soldiers as marines to these ships. Meanwhile, the Byzantines transport his archers, slingers and peltast to the European shore, where Cleitus's victorious forces were encamped. At dawn the next day Antigonus launches an assault by land and sea and catches Cleitus completely by surprise; Cleitus’s entire force is captured or killed.
• Seleucus joins Antigonus against Eumenes and recaptures Babylon.
