Romanus very probably is the same writer of EDB10979 (ICVR VI 15940) with quotation pf Ps 22, 1. The two brothers - Romanus as presbyter, Sergius as a monk - are probably the same who wrote the respective proskynemata edited in ICVR VI 15982. The epitaph edited in ICVR, VI 16001, bearing the Severinus' consulate (year 461 or 482), has evidently to be referred to another presbyter with the same name Romanus (Felle on EDB2828)
Ad B. "Romanus presbyter de quo vide n. 16001 et 15940" (Ferrua in ICVR, comm. ad loc. cit.).
