[1] His bishopric is usually held to have been Ross, the seat of which was at the settlement in the Black Isle called Ros-Maircnidh or Rosemarkie, named after the adjacent promontory A hagiography of Curetán is found in the sixteenth century manuscript known as the Aberdeen Breviary, where his vita occurs under the name "Boniface".
[2] In this hagiography, his Latin name is accompanied by a story of his Hebrew origins, a descendant of the sister of Saint Peter and Saint Andrew, who was first ordained as a priest by the Patriarch of Jerusalem, before travelling to Rome and becoming Pope, later resigning and moving to Pictland.
The story is similar to that in the Life of St. Serf, and it has been conjectured that both were the product of the Romanizing faction in the Easter Controversy.
[3] The Breviary also connects Curetán with King Nechtan mac Der-Ilei, whose brother Bridei was also a guarantor of the Cáin Adomnáin in 697.
There is a clootie well near the village of Munlochy on Black Isle is dedicated to Saint Curetán, whose intercession is believed effective in curing lepers .
