Revetment slab has heavy fascia around outside (W. 0.039) and inside another narrower fascia (W. 0.009). Space between two fasciae preserves shallow, broad chisel marks. This frame encloses panel with spiral motif in corner. There might well have been rows of medallions linked by three knots each.
Preservation description
Two joining fragments broken on three sides preserve front, back, and outer (top?) edge. Slight to moderate, extensive patches of encrustation.
