The Codex Athous Laurae is a manuscript of the New Testament written in Greek uncial letters on parchment.
[1] These letters have breathings (utilised to designate vowel emphasis) and accents (used to indicate voiced pitch changes).
[4] The codex contains a table of contents ("κεφαλαια" / kephalaia) before each book, the Ammonian Sections and Eusebian Canons (early systems of dividing the four Gospels into different sections), lectionary notes in the margin (for liturgical use), musical notes (neumes), and subscriptions.
The codex originally contained the entire New Testament except for the Book of Revelation, with several gaps at both the beginning and end.
In 1892, the biblical scholar J. Rendel Harris did not examine the codex even though he was on a visit to Mount Athos, as he was only inspecting the Septuagint (an early Greek translation of the Old Testament) manuscripts there.
In the Gospel of Luke and John, the Byzantine element is predominate, but with a larger proportion of Alexandrian readings than in Codex Sangallensis 48.
