Editorial summary

Begin with the source’s own compact description: “Tomás Ó Cellaigh” is bishop of Clonfert. The dossier treats that line as a proposition to test through Tomás, Cellaigh and Bishop, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1263, 1259, 1978—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Tomás, Cellaigh and Bishop is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “bishop of Clonfert” 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

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 19, 2025. The linked authority identifier is Q7820543. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1263, 1259 and 1978.

Critical limits

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.

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.
