In the 8th century, Anglo-Saxon Christian art flourished with grand decorated manuscripts and sculptures, along with secular works which bear comparable ornament, like the Witham pins and the Coppergate helmet. The flourishing of sculpture in Mercia occurred slightly later than in Northumbria and is dated to the second half of the 8th century. The Book of Cerne is an early 9th century Insular or Anglo-Saxon Latin personal prayer book with Old English components. This manuscript was decorated and embellished with four painted full-page miniatures, major and minor letters, and continuing panels. Further decorated motifs used in these manuscripts, such as hunched, triangular beasts, also appear on objects from the Trewhiddle hoard (buried in the 870s) and on the rings which bear the names of King Æthelwulf and Queen Æthelswith, which are the centre of a small corpus of fine ninth-century metalwork.
