The schism after the death of Bishop Zosimus was related to the Emperor Honorius by the prefect of the city Symmachus in the letter from 29 December 418 [1299]. The emperor replied Symmachus on 3 January recognizing Eulalius as a bishop of Rome and ordering the exile of Bonifatius (see Letter 15 in the Collectio Avellana). Symmachus fulfilled the orders of the emperor and Eulalius entered the basilica of St. Peter where he celebrated the Mass (see Letter 16 in the Collectio Avellana). Later, however, the party of Bonifatius sent the petition [1339] (6 or 7 January 419) to the emperor and obtained a favourable response [1340] (15 January). The synod in Ravenna on 8 February 419 did not lead to agreement and the emperor forbade both preteders to to return to Rome. He ordered Bishop Achilleus of Spoleto to go to Rome to celebrate Easter on 30 March (the imperial letters in the Collectio Avellana 20-28). Against the imperial interdict, Eulalius went back to Rome, and his followers provoked the riots against Bishop Achilleus (the letter 29 from 18 March 419 of Symmachus to the patricius Constantius in the Collectio Avellana). The prefect Symmachus informed the emperor about the situation, and received the letter 31 in which Honorius ordered him to exile Eulalius [1402]. The present letter dates from 29 March 419 (the day before the Easter Sunday).
