St. Agapitus suffered in his youth a cruel martyrdom at Præneste, now called Palestrina, twenty-four miles from Rome, under Aurelian, about the year 275. His name is famous in the ancient calendars of the Church of Rome. Two churches in Palestrina and others in other places are dedicated to God under his name.
