SECOND CENTURY. This name heads a list of apologists from the early second century, with the few references placing him within the administrative period of Emperor Hadrian* (117-38). These specifically reflect the impact of the incipient Christian Church as a result of imperial policy and rescripts against Christianity by Hadrian and his predecessor Trajan. The occasion for Quadratus's Apology may have been Hadrian's visit to Athens in the winter of 124/5. Other than a brief fragment quoted by Eusebius, this writing is assumed lost, though some suggest it is preserved in the Epistle to Diognetus,* with the Eusebian fragment fitted into the lacuna. The Quadratus who became bishop of Athens subsequent to the martyrdom of Publius could be the apologist.
