Иоанн Малала
We know from the Tunisian inscription that Praesens was a member of the "Quindecimviri sacris faciundis", one of the more prestigious "collegia" of Roman priesthoods. Eusebius of Caesarea and John Malalas both cite a writer called 'Bruttius' or 'Boutios' as a source for events in the reign of Domitian.
