323
year
Year 323 (CCCXXIII) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Rufinus (or, less frequently, year 1076 Ab urbe condita) in Europe. The denomination 323 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.

The poetic work Banquet (Thalia) by the Libyan-born Egyptian Christian priest Arius, age 73, expresses the doctrine that Jesus of Nazareth was not of the same substance as God but rather had a finite nature. As an ascetic, he leads a Christian community near Alexandria, and comes under suspicion of heresy. Arius writes to his former schoolmate Eusebius, bishop of Nicomedia, asking for support. Eusebius writes to other bishops, and when Arius is condemned in September, Eusebius gives him safe haven, and sponsors a synod at Bithynia in October, which nullifies Arius's excommunication (see Council of Nicaea).

Begin with the source’s own compact description: “323” is year. The dossier treats that line as a proposition to test through year, not as a finished interpretation.
Why this record matters
The phrase “year” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Feb 3, 2026. The linked authority identifier is Q32836. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1076.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
