Hosta

Year 290 (CCXC) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Valerius and Valerius (or, less frequently, year 1043 Ab urbe condita). The denomination 290 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.
