Rufinus in his own words, plus Fremantle's prolegomena — which is where the dating of the Olivet years, the Latin Eusebius and the translation programme comes from. NPNF series 2 volume 3: the volume this project already holds for Theodoret and for De Viris Illustribus, so it can be quoted as well as cited.
