St. Sebastian

Today in both forms of the Roman calendar, we commemorate St. Sebastian, the third century martyr. Here is what the Roman Martyrology says:

Also at Rome, ad Catacumbas, St. Sebastian, Martyr, who was in command of the first cohort under the Emperor Diocletian, was ordered to be bound in the middle of a plain, with the title of Christian over his head, and shot with arrows by the soldiers, and lastly to be scourged with rods till he died.
