John Colgan was born in Donegal and educated at Louvain where he entered the Franciscan order in 1618. He was asked to write a history of Irish saints, along with Aodh Mac an Bhaird, and Acta Sanctorum Veteris et Majoris Scotiae seu Hiberniae contains the biographies of saints with feast-days from January to March. He also wrote Trias Thaumaturg on the lives of Saints Patrick, Brigid and Columba, as well as a Life of Johannes Duns Scotus. He retired from the post of Professor of Theology at Louvain in 1645. He was the first to describe the work of Michael O'Clery and his colleagues as The Annals of the Four Masters. [Biography by O'Hanlon]
