Anecdotes
According to hagiographic tradition, Sebastian was an officer of the Praetorian Guard who concealed his Christian faith at the very heart of the imperial palace. He used his position to comfort imprisoned Christians, including Marcellinus and Mark, encouraging them to remain steadfast in the face of torture — an act that could have cost him his life at any moment.
Condemned to death by archery, Sebastian was bound to a post and riddled with arrows by soldiers from his own unit. Left for dead, he was rescued by a Christian widow named Irene of Rome, who removed the arrows and tended his wounds. His miraculous survival became one of the most depicted subjects in European Baroque art.
After his recovery, instead of fleeing Rome, Sebastian chose to confront Emperor Diocletian directly, reproaching him for his persecutions. Astonished to see a man he believed dead, the emperor this time ordered his execution by cudgel. His body was thrown into the Cloaca Maxima, Rome's main sewer.
In AD 680, a terrible plague epidemic struck Rome. A solemn procession was organized around the tomb of Saint Sebastian in the catacombs along the Via Appia, and according to chronicles of the time, the epidemic ceased shortly after. This episode made him the patron saint invoked against epidemics throughout the Middle Ages, most notably during the Black Death in the 14th century.
In several versions of the legend, Sebastian had converted his two fellow soldiers Marcellinus and Mark, twin brothers, who were hesitating to apostatize in order to save their lives. His speech reportedly convinced them so thoroughly that they accepted martyrdom with joy, also bringing about the conversion of their jailers and their families.
