Statius Quadratus' role in the trial of Polycarp provides an important clue to the date of the bishop's martyrdom. Eusebius, in his Chronicle, dates his martyrdom to 166–7; yet a letter from the Christians in Smyrna to those in Philomelium describing his arrest and execution states he was executed on Saturday, Xanthicus 2, i.e. 23 February, in the proconsulship of Statius Quadratus, although two experts have argued independently that Xanthicus 2 should actually be equated to 22 February. Further, a reference in Aelius Aristides has been used to date Quadratus' tenure to 153/154. Of these, that 23 February fell on a Saturday in 155, and 22 February on a Saturday in 156, has convinced most experts to place Polycarp's death in one of those two years. Géza Alföldy dated Statius Quadratus' tenure to 156/157.[2] However, a new inscription shows Gaius Bellicius Flaccus Torquatus as proconsul of Asia in 156/157, pushing Quadratus' proconsulate back to 155/156 or even earlier.[3]
