The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 114
Of the Lake which was removed by Saint Patrick.
The aforementioned Saint Munis, being returned from Rome, disliking after so long a journey the fatigue of any further travel, besought Saint Patrick that as he had provided rest for his brethren who possessed churches, so he would provide for him a dwelling suited unto contemplation. Therefore the saint, knowing that although he loved internal quiet, nevertheless he would be right profitable unto the salvation of many, offered unto him a fitting place, saying: "Behold a hill; behold a valley; build and inhabit where it seemeth pleasant unto thine eyes; yet know thou this: if thou wilt build in the valley, thou mayest bring many souls unto God; but if thou abidest in the hill, thou wilt gain not so many, by reason of the vanities and delights which will attract their eyes, and for very many other causes and reasons." And Munis, foreadvised and forewarned by the Holy Spirit, answered thus: "Neither of the hill nor of the valley do I complain, but of the neighboring lake, nigh unto which is a royal dwelling; for the crowding thither of courtiers and of other secular persons would unto me be an exceeding trouble, and a disturbance unto the Sabbath rest of my mind." Then Saint Patrick, encouraging him, said that God would easily remedy this trouble, and, retiring a little space, poured he forth powerful and prevailing prayers in the presence of God. And on the following night the Lord removed the lake, with all its dwellings and dwellers thereon, so far distant that his servant sustained thence neither trouble nor damage. And Saint Munis, abiding there, builded a church, unto which Saint Patrick bestowed certain relics of the holy Apostles Peter and Paul, and of very many saints, and other ornaments, the which were necessary unto its ecclesiastical ministry. And for his conspicuous virtues he was afterward, although reluctant thereto, advanced unto the episcopal office, for he was renowned for many miracles; and at length he rested in the Lord.
