Facsimile and transcript are accompanied by a detailed introduction, and a commentary on the saints commemorated, by H.A. WILSON (d. 1927), one of the country's outstanding liturgical scholars.
The volume is quarto format. The manuscript calendar dates to 684, was written in c. 703-721, but around 728 was in the possession of St Willibrord, the Northumbrian Apostle of Frisia (658-739). It may be a fragment of a sacramentary now lost.
