In page Antipope Laurentius:

"

A contentious synod held in 502 failed to resolve the schism. Laurentius returned to Rome later that year, and for the following four years, according to the "Laurentian Fragment", he held its churches and ruled as pope, with the support of Festus.[9] Laurentius was only forced from his position when a diplomatic effort to convince Theodoric to intervene succeeded. Conducted chiefly by two non-Roman supporters, the Milanese deacon Ennodius and the exiled deacon Dioscorus, they convinced the king's personal physician, the deacon Helpidius, and then convinced Theodoric to instruct Festus to hand over the Roman churches to Symmachus.[10]
