A text-critical edition of the third speech against the Arians (in Greek) within the Berlin edition of Athanasius Werke. The edition presents the third speech against the Arians, which the Alexandrian bishop Athanaius composed probably between 342-345 CE. The new critical edition of this writing, which because of its dogmatic statements on Christology was often later cited in secondary sources, takes the place of Bernard de Montfaucon’s edition of 1698 and the various reprints of it.
