When the cases of Pelagius and Coelestius were reopened by Zosimus, shortly after the death of Innocent, Julian seems to have expressed himself strongly in their favour in the hearing of Mercator; and when Zosimus issued his "Epistola Tractoria" 577 against the Pelagians (417 CE) and sent it to the major sees of the East and West for subscription, with the notable exception of Antioch, Julian was among those who refused. He was accordingly deposed, and afterwards exiled under the edicts issued by the emperor Honorius in March 418. Julian now addressed two letters to Zosimus, one of which was very generally circulated throughout Italy before it reached the pontiff. Of this Mercator has preserved some fragments. Of the other we have no remains.
