Returning from a pilgrimage to the Holy Land, he became a hermit in the mountain forests of Tuscany.
[1] According to tradition, he was the son of an Irish king called Romanus, who had converted to the Christian faith.
Forsaking his patrimony, he departed for the Holy Land, where he spent several years fasting in the desert.
He was forced to leave after a dispute with a local ruler, removing to Italy, where he lived in the Apennines as a hermit till the age of ninety-seven.
[3] The earliest mention of the church of San Pellegrino in Alpe dates from the early twelfth century.
