AI overview
I don't have enough context to write an accurate overview of "390." The context provided only indicates "year," but doesn't specify which "390" is being referenced (a historical year, a numbered event, a designation, etc.). To write accurately without inventing facts, I would need more specific information about what "390" refers to.

Emperor Theodosius I and Ambrose, by Anthony van Dyck
Year 390 (CCCXC) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Neoterius (or, less frequently, year 1143 Ab urbe condita). The denomination 390 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.
