Herculanus of Perugia was a 6th-century bishop who served the people of Perugia. During the siege of the city by the Ostrogoth king Totila in 549, he reportedly attempted a strategic deception by feeding grain to a lamb to suggest the city possessed abundant food supplies. This tactic failed to prevent the city's fall. Following the capture of Perugia, the bishop was executed, an event that led to his recognition as a saint and his status as the patron of the city.
