The conventional heading has been retained. Literally it is "Tricennial oration of Eusebius, addressed to the Emperor Constantine. Prologue to the praises addressed to Constantine." The translation of this oration shows, even more than that of the Life or Constantine's Oration, a sympathy on the part of the translator with the florid style of Eusebius, and, trying as the style itself is, the success of Bag. in presenting the spirit of the original with, on the whole, very considerable accuracy of rendering has been a constant matter of surprise during the effort to revise. ↩
