The question of the era used in the Roman province of Macedonia is one which has given rise to considerable discussion, but may still be regarded as unsettled. If I attempt briefly to review the principal arguments which have been brought forward and to support a theory which has of late been abandoned by a number of scholars of high authority, my justification must lie partly in the interest of the question itself, partly in the discovery and publication during recent years of some fresh evidence, the value of which appears to me to have been overlooked.
