NOTOC Year 301 (CCCI) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Postumius and Nepotianus (or, less frequently, '*year 1054 *Ab urbe condita'''''). The denomination 301 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.
