Book 5 — Chapter 3 - The Vision Shown to Attalus
Book V centers on the persecution in Lugdunum and Vienna, Irenaeus, the Phrygian prophetic movement, Roman successions, and the major dispute over the date of Pesach. 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 5, Chapter 3, and the full subject is retained under the heading 'The Vision Shown to Attalus'. Names, dates, quoted-source relationships, and political or textual function are kept distinct from Eusebius's own interpretive claims.
