I don't have enough context to write an accurate overview. You've only indicated that "261" relates to a year, but without additional information about what "261" specifically refers to (a historical event, person, publication, etc.), I cannot provide factually accurate details. Could you provide more context about what "261" is?

Quietus (r. 260–261)
Year 261 (CCLXI) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Gallienus and Taurus (or, less frequently, year 1014 Ab urbe condita). The denomination 261 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.
