Peter’s father was a city councillor, his mother was from a noble family, and the boy was raised in a pious household. He received a good education, and was early drawn to religious life, with a personal devotion to Our Lady of the Rosary. Joined the Dominicans in Piedmont, Italy at age 16. He continued his studies, and was ordained at age 25. Noted preacher throughout northern Italy. He worked to bring the heretical Waldensians back to the Church. Appointed inquisitor-general of the Piedmont.

In January 1365 Peter and two Dominican brothers went on a preaching mission through the mountains between Italy and Switzerland, working from the Franciscan friary at Susa, Italy. Peter’s preaching brought many back to the faith, which earned him the anger of the Waldensians. Three of the heretics came to the friary, asked to see Peter, and then murdered him at the gate. Martyr.






Loving God, in your mercy you bestowed the crown of martyrdom on Blessed Peter for his defense of the true faith. Help us by his prayers to please you by a faith that is manifested through charity. We ask this through our Lord Jesus Christ, your Son, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. – General Calendar of the Order of Preachers
