In the period covered by the eleventh century dials inscribed with Anglo-Danish names date themselves. Interlacing undergoes new development, becoming more open and angular, until we get right lined plaits like Wensley, it is better cut, as the later part of the century introduces the masons who rebuilt the churches and began the abbeys. No longer was the work hacked but clean chiselled, and intermingled with new grotesques; we find it at Hackness, in the impost, and in the fonts at Alne and Bowes, where we are already past the era of the Norman Conquest.
Anglian work of the simpler forms and earlier types date 700 A.D.
Full development of Anglian art, middle of eighth century to its close.
Anglian work in decline, or in ruder hands, but not yet showing Danish influence, early ninth century.
Transitional, such as Anglian carvers might have made for Danish conquerors, late ninth century.
Anglo-Danish work showing Irish influence, early half of the tenth century.
Anglo-Danish work with Midland influence, later part of tenth and beginning of eleventh century.
Eleventh century, Pre-Norman.
Post-Conquest, developed out of pre Norman art.
Recumbent monuments were grave-slabs, which may have been coffin lids, such as must have fitted the Saxon rock graves at Heysham, Lancashire, while other forms may have simply marked the place under which a burial was made. They are found with Anglian lettering at Wensley, another has been removed from Yarm, and those of the Durham district are well known.
The two stones at Wensley may have been recumbent, like the Melsonby stones. The Spennithorne slab bears crosses of the earlier Northumbrian type, seen again in the West Wilton slab. At Crathorne are two slabs, with "Maltese" crosses apparently late, all the preceding being of the fine style.
Levisham slab has an Irish Scandinavian dragon.
Grave slabs are found of all periods and styles. Shrine-shaped tombs are known in various parts of England, with pre-Viking ornament. (W. S. Collingwood).
