Mac Nisse of Connor

Our Father among the Saints Mac Nisse (Macanisius), First Bishop of Connor

Bishop · Venerable · d. c. 514 (the annals vary, 506–514)

Commemorated 3 September

Mac Nisse (Latin Macanisius, died c. 514) is the founder-patron of the see of Connor in what is now County Antrim, Ireland — by tradition its first abbot-bishop. Born Óengus, he is called Mac Nisse after his mother Ness, and the tradition of his church makes him a disciple of Patrick, baptised by him and taught the psalms by him. His first foundation is placed by local tradition at the dísert ("desert," hermitage) of Connor, a site later called Kells — the Kells in Antrim, not the famous Columban abbey in Meath — which is why calendar lines style him "abbot of Kells." The Irish annals record his death between 506 and 514; the martyrologies keep him on September 3.

The surviving record of Mac Nisse is a martyrology line, annal obits, notices in the Patrician dossier, and a short and late Latin vita; it allows a sketch, not a biography. The Félire (Martyrology) of Óengus commemorates him at 3 September — "Mac Nisse with thousands, from great Conderi" in Whitley Stokes's translation — and the Martyrology of Tallaght likewise enters Mac Nisse of Condere under this day. The annals register his death under divergent years: 506 (Innisfallen), 508 (Chronicum Scotorum), 510 (Tigernach), with 514 the conventionally received year; Colgan argued for 513/514.

His given name was Óengus; "Mac Nisse" is a matronymic from his mother Ness (or Cnes). The tradition of his church, carried in the Patrician material and the vita, makes him a child of Patrick's own mission: baptised by Patrick, who taught him the psalms and later consecrated him bishop. He founded the church of Connor (Irish Condere) in the valley of the Kells Water in south-central Antrim and governed it as abbot-bishop; the diocese of Connor descends from his foundation and keeps him as patron. A local tradition reported by O'Hanlon places his earlier retreat, and perhaps his first foundation, at the "desert of Connor" about half a mile west of the church of Connor — a site afterwards called Kells — and it is on this tradition that the calendar styling "abbot of Kells" rests.

His Latin vita, preserved in the Codex Salmanticensis, is late and largely legendary: it credits him with healings of the blind and the leprous, the raising of the dead, the diverting of a river, prophecies, and a pilgrimage from which he brought back relics from Rome and the Holy Land. These wonders are recorded here as the content of the vita, not as history. He died, according to the accounts digested by O'Hanlon, on 3 September in early old age.

Feast and commemoration

September 3 (church date; Old Calendar civil September 16). The witness for this commemoration in the Antiochian GB&I layer is the St Constantine York calendar, whose line for this day reads "St. MacNis, abbot of Kells (c. 514)." Orthodox England keeps him this day as "Macanisius," and the September 3 date is that of the ancient Irish martyrologies (Óengus, Tallaght). He does not appear on the OCA's September 3 page (checked live 2026-07-29). He falls under the common of a hierarch (see references/common-readings.md).

Iconography

No ancient iconography of Mac Nisse is transmitted. Modern depictions belong to the Catholic diocese of Down and Connor, of which he is patron — church dedications and twentieth-century stained glass — and are in copyright. No licence-clean image has been located; the entry is listed among the wanted icons.

Disputed questions

  • Which Kells? Three Irish monastic sites bore the name. The Kells of Mac Nisse's tradition is the dísert by Connor in County Antrim; he has no connection with the Columban abbey of Kells in County Meath (founded c. 800, home of the Book of Kells), which did not exist in his lifetime. The York calendar's "abbot of Kells" and Orthodox England's "founded a monastery, probably in Kells" both refer to the Antrim site.
  • Death year. The annals disagree across 506–514 (see above); no resolution is possible, and c. 514 is used here as the received date.
  • Not to be confused with Mac Nisse of Clonmacnoise, a sixth-century abbot of Clonmacnoise (died 585 or 591), whom the Irish martyrologies keep on June 13 — a different saint of the same name.
