The Codex Athous Laurae, designated by Ψ or 044 (in the Gregory-Aland numbering of New Testament manuscripts), or δ 6 (in the von Soden numbering of New Testament Manuscripts), is a manuscript of the New Testament written in Greek uncial letters on parchment. The manuscript has many gaps in the text, as well as containing handwritten notes (known as marginalia). Using the study of comparative writing styles (palaeographically), the codex is dated to the 8th or 9th century. The codex is currently kept in the Great Lavra monastery (B' 52) on the Athos peninsula. Description The manuscript is a codex (precursor to the modern book), containing 261 parchment leaves, which measure , with the text-block being . The text is written in small uncial letters, in one column of 31 lines per page. These letters have breathings (utilised to designate vowel emphasis) and accents (used to indicate voiced pitch changes). The codex contains a table of contents ("" / kephalaia) before each book, the Ammonian Sections and Eusebian Canons (an early system of dividing the four Gospels into different sections), lectionary notes in the margin (for liturgical use), musical notes (neumes), and subscriptions. It is considered one of the oldest manuscripts with musical notes. Textual overview The codex originally contained the entire New Testament except for the Book of Revelation, with several gaps at both the beginning and end. The Gospel of Matthew, the Gospel of Mark 1:1-9:4, and one leaf from the Hebrews with text 8:11-9:19 have subsequently been lost. The order of the codex's books are as follows: the four Gospels the Acts of the Apostles the General epistles the Pauline epistles The General epistles are in an unusual order (1-2 Peter, James, 1-3 John, and Jude; James usually comes before 1 Peter). There is also a shorter ending to the Gospel of Mark before the longer version. This is similar to the ending found in other Greek New Testament manuscripts, such as Codex Regius and all other Greek codices in which the general epistles appear. History The manuscript was seen by biblical scholar C. R. Gregory on August 26, 1886. He described it as the first of its kind. In 1892, the biblical scholar J. Rendel Harris didn't examine the codex even though he was on a visit to Mount Athos, as he was only inspecting the Septuagint (a early Greek translation of the Old Testament) manuscripts
