The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 132
The Miracle which is worked for Certain Hewers of Wood.
And Saint Patrick in his journeying passed with his people through a forest in Midernia, and he met therein certain slaves that were hewing wood; and these men were under the yoke of a hard and cruel master, named Tremeus; and they hewed the wood with blunt axes, nor had they whetstones nor had they any other means whereon to sharpen them. Wherefore their strength failed, their arms stiffened, and the flesh fell from their hands, and the naked sinews were seen, and the miserable men wished rather for death than for life. But when the man of God beheld their misery, he compassionated them, and he touched them, and he blessed their hands and their instruments. Then at the touch and the word of his blessing, all their strength is restored, their hands are healed, their instruments become sharpened, the hardest oaks are hewed down without toil, even as the tenderest twigs; and in these men did the miracle continue until the saint had wondrously obtained for them their freedom.
