Who tried to poison St. Benedict and what about that raven?

The Story of St. Benedict

From Fisheaters:

St. Benedict of Nursia, Italy (A.D. 480-543), the twin brother of St. Scholastica, is considered to be the Father of Western monasticism, and his “Rule of St. Benedict” came to be the basis of organization for many religious orders (his own Order has its cradle at Monte Cassino, Italy, about 80 miles South of Rome).

At any rate, in order to understand the symbolism of the Medal, you must know of this event in St. Benedict’s life: he’d been living as a hermit in a cave for three years, famous for his holiness, when a religious community came to him after the death of their abbot and asked Benedict to take over. Some of the “monks” didn’t like this plan and attempted to kill him with poisoned bread and wine. Just as St. John the Divine was miraculously saved from being poisoned, when St. Benedict made the sign of the Cross over these things, he came to know they were poisoned, so he toppled the cup and commanded a raven to carry off the bread.
