Un dibattito processuale bilingue, il De Trinitate di Faustino Luciferiano, il Salmo 52, ed un’exercitatio scribendi latina: il PSI XIII 1309, un felice riciclo dalla Ossirinco della Tarda Antichità

PSI XIII 1309 is a fragmentary papyrus sheet from Oxyrhynchus whose recto contains a trial debate before the praeses of the province of Arcadia (V AD); this paper offers a new edition and in-depth examination of the documentary recto of the papyrus to provide a more solid basis for judging the literary verso, of which an editio princeps is given. The verso (V AD, second half) contains a few lines of Faustinus Luciferianus’ De Trinitate (of which the papyrus represents the most ancient witness), the complete Psalm 52 following a Latin version exactly known neither by the Vetus Latina nor by Jerome, and a Latin exercitatio scribendi.
