"Translation: "To Marcus Caelius, son of Titus, of the Lemonian voting tribe, from Bologna, a centurion in the First Order of legio XVIII, aged 53; He fell in the Varian War. His bones - if found - may be placed in this monument. Publius Caelius, son of Titus, of the Lemonian voting tribe, his brother, set this up.""
