The consular date may refer to Flavius Severinus, the consul in AD 461, or Severinus Iunior, the consul in AD 482. There are some grafitti at the same cemetery by a presbyter Romanus. We follow Carletti, Felle, and Rüpke in considering him a different person.
According to Rüpke: "It is uncertain whether he is the same as a presbyter Romanus who left his name in three graffiti in the same cemetery, and who was the brother of a monk named Sergius. Against this hypothesis is the fact that graffiti are usually by pilgrims, and would thus indicate an extra-urban presbyter".
On the other hand, Carletti thinks that this Presbyter Romanus could be the author of the grafitti at the same cemetery, with the first line of the Psalm 22 and signature: Romanus (ICUR V, 15940; Epigraphic Database Bari no. 10979, with illustration).
