Coin of Seleucus I (305–281 BC)

Year 305 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Megellus and Augurinus (or, less frequently, year 449 Ab urbe condita). The denomination 305 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

Seleucid Empire

Seleucus, former officer of Alexander the Great, considers himself emperor of Persia. He attempts to recover lands taken by Chandragupta that had been a part of Alexander's Empire. Seleucus establishes Seleucia on the Tigris River as his capital.

Syria

Antigonus I Monophthalmus sends his son Demetrius to conquer Rhodes, which has refused him armed support against Ptolemy. He shows ingenuity in devising new siege engines in his unsuccessful attempt to reduce the city. Among his creations are a battering ram 60 metres long and requiring 1,000 men to operate it and a wheeled siege tower named "Helepolis" (or "Taker of Cities") which stands 40 metres tall and 20 metres wide and weighs 180 tons. This siege of Rhodes earns Demetrius the title Poliorcetes ("the City Besieger").

Roman Republic

The Roman consuls, Marcus Fulvius Curvus Paetinus and Lucius Postumius Megellus, decisively defeat the Samnites in the Battle of Bovianum to end the Second Samnite War.
