The letter is addressed to bishops form Southern Italy: Herculentius (of Potenza), and Stephanus (possibly of Venosa) (see PCBE Italie 1: Genitor). Gelasius I ordered them to make Bishop Reparatus (of unknown place) to submit his presbyter Genitor to their judgement, and to return the slave Septimus to his owner, unless he can prove that he had been free before. B. Neil and P. Allen think that the fragment is a part of the Letter 21 of Gelasius, also dealing with slaves (Neil-Allen 2014: 194).
