Description of Kerbstone 11
Stage 1 comprises a number of motifs, which underlie the Stage 2 carvings that dominate the stone.
They include an incised grid pattern on the left of the main face, with a smaller example just
to the right, Low down is a lightly picked two-turn clockwise spiral enclosed in an arc
(or possibly a third turn of the spiral). A vertical row of chevrons runs down the center
of the main face of the stone. On the top surface, to the left is a double circle with an
arc between the circles and two further arcs outside them.
Stage 2: the carving belonging to this stage occupies both the whole of the stone's main
surface and its top, and is arranged around the natural contours of the stone. The picked
lines are broad and ribbon-like. A vertical line slightly right of center is placed in
a natural hollow of the stone and continues onto the top surface. A narrower line lies
parallel to it on the right, and there is a short, vertical line between the two.
Two large motifs occupy the resulting spaces on the stone.
That on the left is more complete, and from the center outwards consists of a gapped circle,
another around this with slightly squared upper corners, and a third, which is distinctly
squared on the top-right. Five boxed rectangles, which are open at the bottom, enclose this,
again with the top-right corner being more angular than the top-left. An arc runs between
the second and third rectangle from the outside. At the bottom-left these clearly overlie
the stage 1 spiral. The right half of the stone has a similar motif, but this is incomplete
on the lower-right, where the stone is very irregular. All these rectangles are deeply picked
(averaging 10mm in depth), and the natural surface stands out as ridges between the picked channels/ribbons.
