To prevent a possible contest for the papacy, Pope Felix IV, shortly before his death, had taken the unprecedented step of appointing his own successor in the person of the aged Archdeacon Boniface, his trusted friend and adviser. When, however on the death of Felix (Sept. 530) Boniface II succeeded him, the great majority of the Roman priests — sixty out of sixty-seven — refused to accept the new pope and elected in his stead the Greek Dioscorus in the basilica of Constantine (the Lateran) and Boniface in the aula (hall) of the Lateran Palace, known as basilica Julii. Fortunately for the Roman Church, the schism which followed was but of short duration, for in less than a month (14 Oct., 530) Dioscorus died and the presbyters who hadelected him wisely submitted to Boniface. In December, 530, Boniface convened a synod at Rome and issued a decree anathematizing Dioscorus as an intruder. He at the same time (it is not known by what means) secured the signatures of the sixty presbyters to his late rival's condemnation, and caused the document to be deposited in the archives of the church. The anathema against Dioscorus was however, subsequently removed, and the document burned by Pope Agapetus I (535).
