It is said that St. Peter and St. Paul were both martyred on June 29, and, for this reason, their names have been linked in various observances around the world. In Peru, the Día de San Pedro y San Pablo is celebrated in fishing villages because St. Peter is the patron saint of fishermen. Processions of decorated boats carrying an image of the saint are common, and sometimes a special floating altar is set up, with decorations made out of shells and seaweed. Discuss
