167

Year 167 (CLXVII) was a common 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 Aurelius and Quadratus (or, less frequently, year 920 Ab urbe condita). The denomination 167 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.
