Year 492 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Macerinus and Augurinus (or, less frequently, year 262 Ab urbe condita). The denomination 492 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

Greece

• The Persians under Mardonius subdue and capture Thrace and Macedonia.
• Mardonius loses some 300 ships in a storm off Mount Athos, which forces him to abandon his plans to attack Athens and Eretria.

Sicily

• When Camarina, a Syracusan colony, rebels, Hippocrates, the tyrant of Gela, intervenes to wage war against Syracuse. After defeating the Syracusan army at the Heloros River, he besieges the city. However, he is persuaded by the intervention of forces from the Greek mainland city of Corinth to retreat in exchange for the possession of Camarina.

Rome

• Following the conclusion of the secession of the plebs, a famine strikes Rome. The consuls avert the crisis by obtaining grain from Etruria.
