Page "Antipope Eulalius" Paragraph 3

Despite this reversal Eulalius ' position appeared to be the stronger, for he had the support of the Empress Galla Placidia and her husband Constantius, because he had been elected first.

However, Stewart Oost believes this very strength led Eulalius to overconfidence.

He returned to Rome 18 March to celebrate Easter Sunday, but this flouting of the Emperor's orders lost him the support of these two powerful individuals ; the inhabitants of Rome rioted, and the Urban prefect, Aurelius Anicius Symmachus, had his police occupy the Lateran, where Eulalius had made his base, and escort Eulalius out of the city to a house and kept under guard.

On 3 April, the Emperor officially recognized Boniface as the rightful Pope.
