Front face of the incomplete Viking Age cross shaft at St Luke’s, Little Clifton. 144 x 31 x 14.5 cm The stone really does have two different natural colours, as shown on this scan. It must have been quarried across two distinct stratas of sandstone. This would probably not have worried the maker: it is very likely that, like most other early medieval stone sculpture, the whole cross shaft would have been painted. What could be possible specks of green paint and patches of dark gesso may still be visible near the center of the shaft if you zoom right in.
The two figures riding or struggling with serpent-dragon-monsters, look very similar to the ‘Saint’s Tomb’ hogback at Gosforth (see Dominic Powlesland’s model https://skfb.ly/MuGH ).
The bound figure at the foot of the shaft is much like the ‘Loki Stone’ in Kirkby Stephen ( see https://skfb.ly/OxDJ )
