Cogitosus

Cogitosus (fl. c. 650) was an Irish monk, who wrote the Vita Sanctae Brigidae.

Life Cogitosus was a monk of Kildare, an important monastery in Ireland, who wrote the oldest extant vita of Saint Brigid, Vita Sanctae Brigidae, around 650. There is a controversy as to whether he was related to Saint Brigid. Muirchú moccu Machtheni names Cogitosus as the first Irish hagiographer.

Cogitosus writes in fairly good Latin, much better indeed than might be expected in that age, and another in 1993 by Liam da Paor.
