The Red Book of Ossory Digitized and Online – Archive of the Month December 2017
The first Christmas song to appear in the Red Book is headed: ‘Cantilena de nativitate Domini’ [a song of the Nativity of (our) Lord]. Consisting of five stanzas, it opens with the words: ‘verbum caro factum est’ [the Word was made Flesh], RCB Library D11/1.2, folio 70.

As efforts in the RCB Library to digitize and make available its resources to a worldwide audience continue, one of its most significant medieval manuscripts, TheRed Book of Ossory (RCB Library D11/2/1), is now available for public consultation on the Church of Ireland website.

To accompany this significant digital release, the final Archive of the Month for 2017 takes a seasonal turn with Dr Adrian Empey’s analysis of the Christmas–related content of the manuscript, including the lyrics of no less than 25 songs related to the nativity. These, like much of the content of the Red Book as a whole, were written by the Bishop of Ossory, Richard Ledred, whose tempestuous episcopate lasted from 1317 to about 1361.

The Red Book of Ossory contains 79 vellum leaves, and was composed largely in the 14th century during Ledred’s time.  Later entries were added, the latest from the reign of Elizabeth I. The Red Book derives its name from the colour of the leather binding, faded on the outside, but still visible inside the cover.  Like other medieval episcopal registers, it contains a wide range of documents that defy classification, the choice of which depended on what was important to individual bishops, in this case by Ledred, whom Dr Empey makes clear in his presentation was “one of the most extraordinary bishops ever to occupy the see of Ossory”.

The volume is internationally renowned for a number of reasons: it contains, for example, numerous documents of legal interest, such as the provisions of Magna Carta. More exceptionally, it contains a lengthy medical treatise on aqua vitae, or what we would call cognac, that occupies three and a half closely written pages in Latin shorthand.  While such a treatise is perhaps very seasonal, the reasons for its inclusion in the register were more medicinal, perhaps in some way linked to the Black Death that ravaged Kilkenny in 1348. Nevertheless it does provide the earliest known recipe for distillation known to exist in any Irish manuscript and its content of is particular contemporary interest to Ireland’s whiskey industry.

Another reason for the international fame of the Red Book is the collection of 60 Latin lyrics that make up the final folios, all but 13 of which were composed by Ledred. Many of the songs honour the Virgin Mary, and whilst all were not necessarily related to Christmas, Ledred intended them to be sung at the great festivals and on other occasions, so it looks very much as though he had the celebration of Christmas chiefly in mind, analysed in more detail in the online presentation. 

Speaking from the RCB Library, Dr Susan Hood, Librarian and Archivist, says: “We are grateful to Dr Empey for bringing the many intriguing aspects of this volume to light in conjunction with the digital release of this volume. We hope to follow digitization of the Red Book with other medieval manuscripts in the collection in due course.

Dr Adrian Empey, who is a member of the Library and Archives Committee, says: “It is a great delight that the Library has seen fit to make available not just these songs but all of the other unique content of the Red Book of Ossory in digital format for a worldwide audience to view.
