The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 117
The Several Offices of a certain Monastery are appointed by an Angel.
And at another time the angel commanded the aforementioned Fiechus that he should build a monastery on the other side of the river, assigning unto all the offices their fit and proper place; that where a boar should appear unto him, there should he build a refectory, and where a stag should be seen, an oratory. And the saint replied unto the angel that he in no wise could undertake such a work, unless Patrick, his father and pastor, should come and approve thereof. And his words displeased not the angel; for in them he saw the affection and the obedience which Fiechus bore in Christ unto the man of God. And after a few days were past, the angel so advising, Patrick assisted Fiechus, and in the place which is called Forrach builded they a monastery, even according to the direction of the angel. And therein Fiechus presided as abbot; nevertheless throughout his diocese did he fully exercise the episcopal office. And every year, at the beginning of the fast of the Lent time, he went alone out of the monastery, with five barley loaves mixed with ashes for his support, and abided in the wilderness through all that sacred season. But on the Sabbath day which is called Palm-Sunday, or sometimes at the Supper of the Lord, he was wont to return unto his monastery for the discharge of his holy office, always bringing with him the half of one loaf yet uneaten. And he sent before him unto God threescore saints, whom when he followed he was buried in Scleptus. And his son aforementioned imitated his father in wisdom and holiness; and having in another place attained the episcopal degree, he rested in the Lord.
