Source-derived summary

Year 403 (CDIII) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Theodosius and Rumoridus (or, less frequently, year 1156 Ab urbe condita). The denomination 403 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.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “403”, the useful work is to connect “year” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q32757. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1156.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
