Source-derived summary

Pope Sylvester I (also Silvester, before 284 – 31 December 335) was the bishop of Rome from 31 January 314 until his death on 31 December 335. He filled the See of Rome at an important era in the history of the Western Church, though very little is known of his life.

During his pontificate, he notably convened the Council of Arles in 314, which condemned the separatist Donatist sect, and the First Council of Nicaea in 325, which aimed to resolve the Arian controversy.

Sylvester I's pontificate coincided with the construction of churches including Old St. Peter's Basilica, the Basilica of the Holy Cross in Jerusalem (Santa Croce in Gerusalemme), as well as the Archbasilica of Saint John Lateran. His feast is celebrated as Saint Sylvester's Day, on 31 December in Western Christianity, and on 2 January in Eastern Christianity.

Personal biography

The accounts of his pontificate preserved in the seventh- or eighth-century Liber Pontificalis contain little more than a record of the gifts said to have been conferred on the church by Constantine I, although it does say that he was the son of a Roman named Rufinus.

Pontificate

Large churches were founded and built during Sylvester I's pontificate, including Basilica of St. John Lateran, Basilica of the Holy Cross in Jerusalem, Old St. Peter's Basilica and several churches built over the graves of martyrs.

Editorial summary

Begin with the source’s own compact description: “Pope Sylvester I” is 33rd pope and saint (reigned 314-335). The dossier treats that line as a proposition to test through Pope, Sylvester and 33rd, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 227-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Pope, Sylvester and 33rd is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “33rd pope and saint (reigned 314-335)” 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.

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 28, 2026. The linked authority identifier is Q47149.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
