Latin chapter divisions in Ephesians

Ephesians divided into 31 chapters/sections in Codex Amiatinus

I've been preparing for my paper at the Birmingham Colloquium on New Testament Textual Criticism coming up on April 11. And I've been looking at Latin chapter systems for Ephesians.

There's at least seven different chapters systems in the Latin tradition, all with accompanying titles. But we only have two chapter systems in the Greek tradition (and only one of them also has titles — the Euthalian κεφάλαια system) 🤔

This is Codex Amiatinus from the early 8th century:

It begins with a list of 31 chapters for Ephesians, along with titles.

My sense is that “chapters” is not quite the right English word to describe what Codex Amiatinus is doing. They are more like numbered sections/paragraphs.

Donatien De Bruyne has a monograph, Sommaires, Divisions et Rubriques de la Bible Latine, which records data on Latin chapter systems:

Codex Amiatinus falls into De Bruyne's A group and you can see the precise divisions below:

I think Codex Amiatinus does a very good job in structuring Ephesians into 31 sections. It follows the literary contours and flow of Paul’s thought.

I would love any bibliographic recommendations on Latin capitula. In addition to De Bruyne, so far I've looked at:

• Thomasius, Opera Omnia, tomus primus continens sacrorum bibliorum veteres titulos sectiones (1747).

• P.-M. Bogaert, "Les particularités éditoriales des Bibles comme exégèse implicite ou proposée, Les sommaires ou capitula donatistes," in Lectures Bibliques: Colloque du 11 novembre 1980 Bruxelles.

• Samuel Berger, “Les chapitres et les sommaires des livres de la bible,” in Historie de la Vulgate (1893).

• Hermann Josef Frede, Excursus 2 in Vetus Latina 25.1, pp. 120-31.

• Hugh A. G. Houghton, “Chapter Divisions, Capitula Lists, and the Old Latin Versions of John,” Revue Bénédictine 121.2 (2011): 316–56.

• Maniaci, “Chapter lists in Giant and Beneventan Bibles” in Synopses and Lists: Textual Practices in the Pre-Modern World (Cambridge: Open Book Publishers, 2023), 282-321.
