The exact time and date of the making of the first Saint Benedict Medal are not clear. The medal was originally a cross, dedicated to the devotion in honour of St. Benedict. At some point medals were struck that bore the image of St. Benedict holding a cross aloft in his right hand and his Rule for Monasteries in the other hand. Then a sequence of capital letters was placed around the large figure of the cross moline on the reverse side of the medal. The meaning of what the letters signified was lost over time until around 1647 an old manuscript was discovered at the Benedictine St. Michael's Abbey in Metten. In the manuscript, written in 1415, was a picture depicting St. Benedict holding in one hand a staff which ends in a cross, and a scroll in the other. On the staff and scroll were written in full the words of which the mysterious letters were the initials, a Latin prayer of exorcism against Satan. The manuscript contains the exorcism formula "Vade retro satana" ("Step back, Satan"), and the letters were found to correspond to this phrase.
