Year 498 (CDXCVIII) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Paulinus and Scytha (or, less frequently, year 1251 Ab urbe condita). The denomination 498 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.
