Book 4 — Chapter 14 - Polykarpos, Companion of Those Near the Emissaries
Book IV moves through Trajan, Hadrian, Antoninus, and Marcus Aurelius, including the Bar Kokhba war, early apologists, Polykarpos, Justin, Hegesippus, Melito, Tatian, and Bardaisan. The material overlaps the Smyrnaean martyrdom tradition: Polykarpos is remembered as an elderly overseer connected with earlier witnesses, questioned by the Roman proconsul, and killed after refusing the required public renunciation. In this reconstruction the chapter coordinate is preserved as Book 4, Chapter 14, and the full subject is retained under the heading 'Polykarpos, Companion of Those Near the Emissaries'. Names, dates, quoted-source relationships, and political or textual function are kept distinct from Eusebius's own interpretive claims.
