Year 492 (CDXCII) was a leap year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Anastasius and Rufus (or, less frequently, year 1245 Ab urbe condita). The denomination 492 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.
- Isaurian War: The Isaurians begin a revolt against emperor Anastasius I in southern Central Anatolia. The rebels are defeated by the Eastern Roman army under John the Scythian and John the Hunchback in the Battle of Cotyaeum (subordinate commanders including the future Justin I). They retreat to their mountain fortresses and continue a guerrilla warfare against the Roman forces until 497.
