Saint Francis of Assisi is invoked as patron of merchants. Giovanni di Pietro di Bernardone, called Francesco, was born at Assisi in 1181 or 1182, son of the prosperous cloth merchant Pietro Bernardone. After a year as a prisoner of war at Perugia (1202-1203) and a serious illness, he experienced a conversion that culminated in 1206 with his renunciation of his patrimony before Bishop Guido of Assisi.
