Book 6 — Chapter 33 - The Teaching of Beryllus
Book VI is dominated by Origen and the intellectual life of Alexandria and Caesarea, then the persecutions under Severus, Maximinus, and Decius, with Dionysius of Alexandria becoming a principal witness. The chapter advances Eusebius's chronological chain by identifying the people, writings, disputes, and public events that connect one generation of the assemblies to the next. In this reconstruction the chapter coordinate is preserved as Book 6, Chapter 33, and the full subject is retained under the heading 'The Teaching of Beryllus'. Names, dates, quoted-source relationships, and political or textual function are kept distinct from Eusebius's own interpretive claims.
