[1] After a youth of precocious piety, he was received at the age of ten among the canons regular of the Priory of St. Peter's at Fermo.
Three years later, desirous of leading a more austere life, he entered the Order of Friars Minor, where he was influenced by James of Fallerone.
[1][2] Shortly after his profession, John was sent by the Minister General of the Order to Mount La Verna in Tuscany.
[2] John's later years, however, were devoted to Christian ministry, and he preached at Florence, Pisa, Siena, Arezzo, Perugia and many other towns of northern and central Italy, where many miracles were attributed to him.
Feeling the approach of death at Cortona while on his way to Assisi, John returned to La Verna and died there at the age of 63 in 1322.
