Cailtan of Iona

Cailtan of Iona, also called Coelten or Colga, is reckoned a monk at Iona in Scotland. His commemoration on 25 February is uncertain; the day follows the Julian calendar of the medieval martyrologies.

Camerarius records him on this day in his calendar, and Bishop Forbes gives some details about Cailtan or Colga. According to a treatise ascribed to Saint Oengus, Cuillenda was the mother of Cailtan, also called Colgan, Colgius or Colga; his sister was Faillen and his brothers Aedh and Sorar. Camerarius and Dempster make him an abbot, and Dempster gives him the day of 13 March. O'Hanlon notes that some Scottish writers confuse the names Cailtan and Colga, which seem to him quite distinct, and asks whether this monk may be the same as Colgius, son of Aid Draigniche. He is honoured in the Irish calendars, with no synodal canonization shown in the source.
