__NOTOC__
Year '''257''' ('''[[Roman numerals|CCLVII]]''') was a [[common year starting on Thursday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of Valerianus and Gallienus''' (or, less frequently, '''year 1010 ''[[Ab urbe condita]]'''''). The denomination 257 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.
