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. This additional material appears at the beginnings of books, in the margin of the text, and at the ends of books, as well as in line and paragraph separations. This material is traditionally associated with the name of Euthalius.
