The Editions and Translations of this work are substantially identical with those of the Life, above, but some of the earlier ones do not contain the work. It was delivered in the year 336 (or possibly 335) at Constantinople, in celebration of the thirtieth anniversary of Constantines accession, Constantine himself being present (cf. V.C. 4. 46 and O.C. 1). It gave the emperor lively satisfaction, from which one may safely infer a peculiar taste for combined panegyric and philosophical theology unless the hypothesis of a double work be true. According to this hypothesis the work consists of two separate orations, spoken perhaps at different times, the first including chapters 1–10, which are panegyrical in character, and the other chapters 11–18, which are theological (compare Lightfoot, Eusebius, p. 343; also McGiffert, Prolegomena, p. 43). It is like the oration of Constantine, a proper part of the Life of Constantine being appended according to his promise in Bk. 4, ch. 46.
The special points relating to these works are treated in the notes.
