October 4 is the Feast of Saint Petronius, bishop of Bologna in the 5th century. The Bolognese honor Petronius as their patron saint and dedicated the city’s main church to him. Rising high over the city’s Piazza Maggiore, San Petronio stands as the world’s fifth largest church. The young Michelangelo carved an image of San Petronio for the tomb of St. Dominic, also in Bologna.
