__NOTOC__
Year '''366''' ('''[[Roman numerals|CCCLXVI]]''') was a [[common year starting on Sunday]] of the [[Julian calendar]]. At the time, it was known as the '''Year of the Consulship of [[Gratian|Gratianus]] and [[Dagalaifus (magister equitum)|Dagalaifus]]''' (or, less frequently, '''year 1119 ''[[Ab urbe condita]]'''''). The denomination 366 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.
