 The term used is that Cogitosus was his “father,” but it is generally agreed upon by scholars that this was a figurative term, meaning spiritual father or spiritual companion.Muirchú is most certainly referring to the same Cogitosus who wrote a hagiographical "Life of St. Bridget" in the earlier seventh century.If Muirchú is to be believed, this would make him one of the earliest Irish hagiographers of any saint, second to Cogitosus.
