Book of Deer

The Book of Deer (Leabhar Dhèir in Gaelic) (Cambridge University Library, MS. Ii.6.32) is a 10th-century Latin Gospel Book with early 12th-century additions in Latin, Old Irish and Scottish Gaelic. It is noted for containing the earliest surviving Gaelic writing from Scotland.

The origin of the book is uncertain, but it is reasonable to assume that the manuscript was at Deer, Aberdeenshire, Scotland when the marginalia were made. It may be the oldest surviving manuscript produced in Scotland (although see Book of Kells), and is notable for having possibly originated in what is now considered a Lowland area. The manuscript belongs to the category of Irish pocket gospel books, which were produced for private use rather than for church services. While the manuscripts to which the Book of Deer is closest in character are all Irish, most scholars argue for a Scottish origin. The book has 86 folios and measures 54 mm by 107 mm. It is written on vellum in brown ink and is in a modern binding.

The Book of Deer has been in the ownership of the Cambridge University Library since 1715, when the library of John Moore, Bishop of Ely was presented to the University of Cambridge by King George I.

The Latin text contains the complete text of the Gospel of John, portions of the Gospels of Matthew, Mark and Luke, a portion of an Office for the Visitation of the Sick, and the Apostles' Creed. It ends with a colophon in Old Irish. The Gospel texts are based on the Vulgate but contain some peculiarities unique to Irish Gospel books. The texts are written in an Irish minuscule text, apparently by a single scribe. Although the text and the script of the manuscript place it squarely in the tradition of the Irish Pocket Gospel, scholars have argued that the manuscript was produced in Scotland.
