And there were holy women as well as holy men in Ireland. St. Brigid was held in such honor that she is often called the Mary of the Gael. Even in St. Patrick’s day, she had founded a convent at Kildare, beside which was a monastery of which St. Conleth was superior; and she founded many other convents in addition to that at Kildare. Her example was followed by St. Ita, St. Fanchea, and many others; and if at the close of the sixth century there were few districts which had not monasteries and monks, there were few also which had not convents and nuns.
Nor was this all. Fired with missionary zeal, many men left Ireland to plant the faith in distant lands. Thus did St. Columcille settle in Iona, whence he converted the Picts. Under his successors, St. Aidan and his friends went south to Lindisfarne to convert Northumbria in England; and the ninth abbot of Iona was the saintly Adamnan, whose biography of St. Columcille has been declared by competent authority to be the best of its kind of which the whole Middle Ages can boast. Nor must it be forgotten that the monasteries of Luxeuil and Bobbio owed their origin to St. Columbanus; that St. Gall gave his name to a town and canton in Switzerland; that St. Fridolin labored on the Rhine and St. Fursey on the Marne; and that St. Cathaldus was Bishop of Tarentum, and is still venerated as the patron of that Italian see.
And if we would know what was the character of the schools in which these men were trained, we have only to remember that Colgu, who had been educated at Clonmacnois, was the master of Alcuin; that Dicuil the Geographer came from the same school; that Cummian, Abbot and Bishop of Clonfert, combated the errors about the paschal computation with an extent of learning and a wealth of knowledge amazing in a monk of the seventh century; and that at the close of the eighth century two Irishmen went to the court of Charlemagne and were described by a monk of St. Gall as “men incomparably skilled in human learning”. The once pagan Ireland had by that time become a citadel of Christianity, and was rightfully called the School of the West, the Island of Saints and Scholars.
