Year 257 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Regulus and Blasio (or, less frequently, year 497 Ab urbe condita). The denomination 257 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
The Battle of Tyndaris is fought between the Roman fleet (with Gaius Atilius Regulus in command) and the Carthaginian fleet off Tyndaris (modern Tindari) in Sicily. Hiero II, tyrant of Syracuse, has allowed Tyndaris to be a base for the Carthaginians. However, after this battle, the town falls to Roman forces.
The State of Chu and the State of Wei send armies to assist Zhao against the Qin, and they defeat the Qin army of Wang He outside Handan. This forces Wang He to lift the siege.
