Euthalian Apparatus

The Euthalian Apparatus is a collection of additional editorial material, such as divisions of text, lists, and summaries, to the New Testament's Book of Acts, Catholic epistles, and Pauline epistles.

To Euthalius were also referred a division of the Acts into 16 αναγνωσεις (lessons) and of the Pauline epistles into 31 sections.

[8] Bruce M. Metzger stated: "How much of this supplementary material was drawn up by Euthalius and how much was added later is not known.
