[...] And presbyter Marcellus, together with the presbyters and the deacons, during the night collected the bodies [of the martyrs], with chants, and he buried them on the Via Salaria, in the cemetery of Priscilla, in a cubiculum that is accessible even today, as he [Marcellinus] had ordered when he repented while he was being conducted towards execution, in the crypt near the corpse of Saint Crescentius, on 25 April. [...]
Marcellus later becomes the bishop of Rome himself: the next notice in the Liber Pontificalis is about him.
