- John of the Holy Trinity
Benedictine Vallombrosan monk at Florence, Italy, taking the religious name John of the Holy Trinity. Developed a fascination with black magic, and began to study and practice it in secret, collecting occult and forbidden writings. Eventually found out and summoned before the abbot-general of the Vallumbrosans, John first denied his studies, then confessed. He was imprisoned by the Order, which proved to be his salvation. The solitude led him to true penitence, and some severe self-imposed autsterities. Seeing his conversion, his brothers asked that he return to the community, but he refused, preferring the saving solitude of his cell. He lived to old age as a hermit, writing, and receiving visions of Saint Catherine of Siena.
