The primary purpose of this article is to draw attention to a little-known Anglo-Saxon manuscript of the early ninth century, now Paris, Bibliothèque Nationale, lat. 10861, a collection of Latin saints' lives or passions. My interest was first drawn to this manuscript by the brief remarks of J. J. G. Alexander and J. E. Cross (the latter incorporating the personal communication of Bernhard Bischoff), both of whom associated the manuscript with the more famous Book of Cerne (Cambridge, University Library, Ll. 1.10) by virtue of its script and decoration. Closer examination of the manuscript reveals far more complex connections and implications. In particular, the script of BN lat. 10861, which incorporates several distinctive calligraphic features, relates it closely to a group of charters produced at Christ Church, Canterbury, and dated between c. 805 and c. 825. There have hitherto been few attempts to link Anglo-Saxon documentary and book hands, with the notable exceptions of the link between Oxford, Bodleian Library, Bodley 426 (Philippus, Expositio in Iob), which has been dated to the mid-ninth century on the basis of its association with two charters (London, British Library, Cotton Augustus ii. 37, dated 838, and Cotton Charter viii. 36, dated 847) thought to have been written in Wessex, probably at Sherborne or Winchester, and the association of London, BL, Royal 1. E. VI and BL, Add. Ch. 19789, a ninth-century forgery of a document dated 759, recently advanced by Mildred Budny. The establishment of such relationships offers potential for a firmer assessment of the date and place of origin of a particular manuscript than might otherwise be possible; it may also provide a valuable insight into the workings of the scriptorium in question. If, as I believe, a reasonably accurate dating may be advanced for BN lat. 10861 through its association with charter material, further chronological implications may arise, for the decoration of this manuscript places it firmly within the ‘Canterbury’ or ‘Tiberius’ group of manuscripts, and the dating of any one member of the group offers scope for the relative dating of others.
