__NOTOC__
Year '''423''' ('''[[Roman numerals|CDXXIII]]''') was a [[common year starting on Monday]] of the [[Julian calendar]]. At the time, it was known in Rome as the '''Year of the Consulship of [[Avitus Marinianus|Marinianus]] and [[Asclepiodotus (consul 423)|Asclepiodotus]]''' (or, less frequently, '''year 1176 ''[[Ab urbe condita]]'''''). The denomination 423 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.
