Luchesio Modestini was a 13th-century merchant from Poggibonsi who became a foundational figure in the Franciscan Third Order. Originally a soldier and a trader known for his focus on material wealth, he underwent a spiritual conversion alongside his wife, Buonadonna de' Segni. Following the guidance of Francis of Assisi, the couple dedicated their lives to penance and charity while remaining in the world. He is recognized as a blessed within the Catholic tradition for his devotion and ascetic lifestyle.
Life and conversion
After serving in the Ghibelline army, Modestini settled in Poggibonsi to work as a merchant. Following a profound change of heart, he and his wife abandoned their pursuit of wealth to practice extreme asceticism and works of mercy. They distributed most of their possessions to the needy, living simply on small plots of land. Tradition holds that they were the first followers to join the Franciscan Order of Penance after consulting with Francis himself.
Death and veneration
Modestini died in 1260, shortly after his wife passed away following his prayer for them to die together. His beatification was approved by Pope Gregory X in 1274. He is venerated in the Catholic Church, with his feast day observed on April 28. His shrine in Poggibonsi has historically been a site where people have sought spiritual assistance.
