Textus Roffensis

The Textus Roffensis (Latin for "The Tome of Rochester"), fully entitled the Textus de Ecclesia Roffensi per Ernulphum episcopum ("The Tome of the Church of Rochester up to Bishop Ernulf") and sometimes also known as the Annals of Rochester, is a mediaeval manuscript that consists of two separate works written sometime between 1122 and 1124. It is catalogued as "Rochester Cathedral Library, MS A.3.5" and is currently on display in a new exhibition at Rochester Cathedral, Rochester, Kent. It is thought that the main text of both manuscripts was written by a single scribe, although the glosses to a Latin entry were made by a second hand.

A textus was a book with a decorated cover suitable to be kept in the church by the high altar. The term does not mean a text concerning Rochester Cathedral. A liber was a less decorated book, suitable only for the cloister. It is rare that a secular book is a textus, and the name given to the Textus Roffensis by the cathedral is considered indicative of the book's importance during the Middle Ages.

The two manuscripts were bound together in around 1300. The first part is a collection of documents which includes the Law of Æthelberht, attributed to Æthelberht of Kent (c. 560–616), and the 1100 coronation charter of Henry I of England. The Law of Æthelberht is the oldest surviving English law code and the oldest Anglo-Saxon text in existence. The second part of the Textus Roffensis is the oldest of the Rochester Cathedral registers. The entire volume consists of 235 vellum leaves.

Over the centuries, the Textus Roffensis has been loaned, lost and recovered on several occasions and has been in the custody of a variety of different people and places: it is now held at the Medway Archives Office in Strood. Sometime between 1708 and 1718 the book was immersed for several hours in either the River Thames or the River Medway when the ship transporting it overturned; water damage is apparent on a number of pages.
