The British Library’s Medieval manuscript blog
has an illustrated post about the use of interlace decoration in Anglo-Saxon book illustrations and of the appearance of the style in so-called Franco-Saxon manuscripts and and also further afield in Europe. As a motif it also occurs in Hiberno-Scottish, Anglo-Saxon and Anglo-Danish sculpture, notably standing cross shafts. Not only does the post look at questions of transmission but also affords a glimpse of the artistry and individuality of medieval scribes. The post can be viewed at Early medieval interlace – a distinctive or ubiquitous feature?
