SS Maurus and Placid OSB: October 5
SS Maurus and Placid were both offered to St Benedict as child oblates, to be brought up in monastic life, at the same time. St Gregory's Life describes a number of incidents relating to them both:
Ch3 : SS Maurus and Placid are brought to the monastery, Maurus old enough to be St Benedict’s assistant, but Placid still very young.
Ch 4: St Maurus sees the demon plaguing a monk of one of St Benedict’s monasteries, although the superior of the community cannot;
Ch 5: St Benedict finds a miraculous spring of water for the monastery after a night in prayer with the boy Placid
Ch 6: St Maurus retrieves a lost tool from the bottom of the lake;
Ch 7: how St Maurus walked on water (pictured above);
Ch 8: St Benedict rebukes St Maurus for rejoicing at the death of a priest enemy of St Benedict who had died.
St Maurus in particular was an extremely popular saint in the middle ages, but, like so much of the Church's tradition, he has fallen a victim of the search for the 'real historical' saint, as well as the vexed debate over the early spread of the Rule of St Benedict.
Traditionally, St Maurus was thought to have founded the monastery of Glanfeuil Abbey in France, which certainly fits with the known early spread of the Rule to that country; St Placid was traditionally believed to have been martyred.
