Nicene and Post-Nicene Fathers, Ser. II, Vol I:
The Life of Constantine with Orations of Constantine and Eusebius.: Chapter XXXIX

Chapter XXXIX.—Constantine’s Entry into Rome.

Having then at this time sung these and suchlike praises to God, the Ruler of all and the Author of victory, after the example of his great servant Moses, Constantine entered the imperial city in triumph. And here the whole body of the senate, and others of rank and distinction in the city, freed as it were from the restraint of a prison, along with the whole Roman populace, their countenances expressive of the gladness of their hearts, received him with acclamations and abounding joy; men, women, and children, with countless multitudes of servants, greeting him as deliverer, preserver, and benefactor, with incessant shouts. But he, being possessed of inward piety toward God, was neither rendered arrogant by these plaudits, nor uplifted by the praises he heard: 3136 but, being sensible that he had received help from God, he immediately rendered a thanksgiving to him as the Author of his victory.
