Book 6 — Chapter 12 - Serapion and His Surviving Works
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. Eusebius's library work is central here. He names books, quotations, disputed writings, teachers, and chains of reception, often preserving information about works that later disappeared. In this reconstruction the chapter coordinate is preserved as Book 6, Chapter 12, and the full subject is retained under the heading 'Serapion and His Surviving Works'. Names, dates, quoted-source relationships, and political or textual function are kept distinct from Eusebius's own interpretive claims.
