Ottone Frangipane was a Benedictine monk and hermit who lived from approximately 1040 to 1127. Born into a powerful Roman baronial family, he initially served as a knight before a miraculous escape from imprisonment led him to pursue a life of religious devotion. He practiced asceticism at various abbeys and later settled in Ariano Irpino, where he served pilgrims and lived as a recluse. He is recognized as a saint in the Catholic tradition and is celebrated for his piety and his service to travelers.
Life and devotion

After being freed from chains through divine intervention, Ottone abandoned his military life to follow the Rule of St. Benedict. He sought spiritual guidance at the Abbey of Cava de' Tirreni and later at Montevergine. In Ariano Irpino, he founded the hospital of San Giacomo to assist pilgrims. By 1120, he embraced the life of a hermit, living in a secluded cell where he practiced constant prayer, fasting, and penance.
Veneration and legacy
He is the patron saint of Ariano Irpino, the diocese of Ariano Irpino-Lacedonia, and Castelbottaccio. His feast day is observed on 23 March. Local tradition credits his intercession with protecting the city from various disasters, including plagues and earthquakes. In religious art, he is often depicted wearing monastic clothing and carrying a sword or a scourge.
