In 1106 Henry V, Holy Roman Emperor had a vision of the saint and translated his relics to the church of San Giorgio in Ferrara. This led to a more intense veneration of the saint and in 1463 he was made Ferrara's patron saint. The saint also became a major subject in Ferrarese art, such as Cosmè Tura's 1470 Saint Maurelius Altarpiece for San Giorgio church.
