Book 4 — Chapter 9 - Hadrian's Rescript against Punishment without Trial
Book IV moves through Trajan, Hadrian, Antoninus, and Marcus Aurelius, including the Bar Kokhba war, early apologists, Polykarpos, Justin, Hegesippus, Melito, Tatian, and Bardaisan. A major feature of the chapter is documentary: Eusebius transmits, summarizes, or frames a letter, decree, or other writing because he wants the reader to see the institutional record rather than rely on his narration alone. In this reconstruction the chapter coordinate is preserved as Book 4, Chapter 9, and the full subject is retained under the heading 'Hadrian's Rescript against Punishment without Trial'. Names, dates, quoted-source relationships, and political or textual function are kept distinct from Eusebius's own interpretive claims.
