 Boeri died shortly afterwards.He was the author of two commentaries on the Rule of St. Benedict; in one, written when he was Abbot of St. Chinian, he deals with the Rule from the point of view of the canonist; in the other, written in the Sacro Speco at Subiaco when he was Bishop of Orvieto, he deals with it more from the point of view of the ascetic.He dedicated the later commentary to Charles V, King of France.
