John Colgan
John Colgan, OFM (Irish Seán Mac Colgan; c. 1592 – 15 January 1658), was an Irish Franciscan friar noted as a hagiographer and historian. Life
Colgan was born c. 1592 at Priestown near Carndonagh, a member of the Mac Colgan sept of Inishowen. He left Ireland for the Continent around 1612 and was ordained a priest in 1618. Colgan joined the Franciscan Order in 1620 and was sent to study in the Irish Franciscan College of St. Anthony of Padua in Leuven, where one of his teachers was Thomas Fleming. Colgan became a lecturer in philosophy at Aachen, then in 1628 he taught scholastic theology at Mainz, before returning to Leuven in 1634 as novice master. St Anthony's trained friars for the Irish mission. Sometime previously, in consultation with Friar Luke Wadding of the College of St. Isidore in Rome, Friars Hugh Ward and Patrick Fleming (†1631) had set about preserving information regarding Irish history and culture. They planned a complete history of the Irish saints. Ward maintained close contacts with the Bollandists. Ward sent a number of his colleagues, notably Michael O'Clery, to Ireland and elsewhere to collect or copy manuscripts, but died before much progress was made. While in Mainz, Colgan had offered to copy hagiographical material in various libraries. Upon Ward's death in 1635, Colgan became professor of theology and took over direction of the Irish history and letters project. A competent master of the Irish language, he had thus ready at hand an excellent collection of manuscripts of Irish hagiology. He undertook a great work, to be published in six volumes, dealing with the whole range of Irish ecclesiastical history and antiquities. In 1645 he published at Louvain the  Acta Sanctorum Hiberniae, containing the lives of the Irish saints whose feasts occur in the calendar for the months of January, February, and March. Hugh O'Reilly (Archbishop of Armagh) covered part of the cost. The second volume of the series, entitled Acta Triadis Thaumaturgae (The Acts of a Wonder-Working Triad), appeared at Louvain in 1647. It deals with the three great national saints of Ireland, Patrick, Brigid, and Columbcille. For a long time the Trias Thaumaturga was nearly the only source of information on St. Patrick. Colgan's former teacher, Thomas Fleming, now Archbishop of Dublin defrayed most of the expense. Colgan's manuscript seems to have entirely disappeared. Besides the "Lives" in the Trias Thaumaturga, there are also contained in this volume many valuable "Appendices", dealing with the ecclesiastical antiquities of Ireland, and critical and topographical notes, which, though not always correct, are of assistance to the student. In 1655 he published at Antwerp a life of Duns Scotus, in which he undertook to prove that this great Franciscan doctor was born in Ireland, and not in England, as was then asserted. In 1652 Colgan resigned as a professor, dying at St. Anthony's, Leuven, on 15 January 1658 aged 66. Works

Colgan's work on Irish hagiology is of undoubted value. Though unfortunately of very weak constitution, he was a man of great ability and industry, and with a sound critical sense. His knowledge of the Irish language enabled him to turn to good account the vast collection of manuscripts (now for the greater part lost around the time of the French Recolution) which had been collected at the instigation of Ward, while his acquaintance with the traditions existing among the native Irish of his time, about the various names of persons and places, gave him an advantage over later writers. In some instances, his work is the only extent copy of manuscripts consulted. Seamus Deane called Colgan one of the more ‘scientific’ historians of his time. The Colgan Heritage Weekend is held annually in Carndonagh, Co. Donegal, his home place, at the end of June. His principal works are:
