Giovanni Liccio was a 15th-century Dominican priest from Caccamo, Sicily, recognized for his asceticism and preaching. Born into a poor family, he was reportedly associated with a miraculous healing during his infancy, which led his father to allow a neighbor to help raise him. After joining the Order of Preachers in 1445, he established a priory in his hometown and eventually served as a provincial for Dominican houses in Sicily. He is remembered as a thaumaturge who performed various healings and provided for the needy.
