Saint Sabina Martyr was a noble pagan, wife of Senator Valentino, was converted to Christianity by her maid Serapia. She was accused of being a Christian by Elpidio the Perfect (at the time), after having placed, in the family Sepulcher the holy body of Serapia, (who is also a martyr). Killed because she declared herself inscribed in the new religion, she courageously professed her faith in Christ.

Saint Sabina suffered martyrdom on the 29th of August in the year 125 under Emperor Hadrian. Her relics, together with those of the Saints Serapia, Alexander, Evenzio and Teodulo are venerated under the High Altar of the Roman Basilica which bears her name.
