In Gabriel Bucelin's 1679 "Benedictus redivivus", he recounts several incidents in which St. Benedict's Medal was viewed as efficatious in addressing illness or some local calamity. In the 1743 "Disquisitio sacra numismata, de origine quidditate, virtute, pioque usu Numismatum seu Crucularum S. Benedicti, Abbatis, Viennae Austriae, apud Leopoldum Kaliwoda", Abbot Löbl, of St. Margaret's Monastery of Prague, recommended recourse to the medal as a remedy against bleeding. Prosper Guéranger relates several incidents of religious conversions which he attributes to the intercession of St. Benedict through the pious use of the medal.
