Fig.68This is a particularly enigmatic stone from the Ollantaytambo wall (fig.68): Although the surface of the stone is quite
rough and could very well have been hewn, it is very difficult to explain the zigzagging pattern on the face of the stone.
While it is true that the ‘stairway’ pattern is a motif common to many Mayan structures, notice how the bottom section
of the lower zigzag appears to have protruded slightly and sagged a little. It seems quite unlikely and somewhat
unreasonable to think that something like this would have been purposely carved onto the surface of the wall? Other
sections look as if they have been slapped with blocks or prodded with the end of sticks while the material was still soft
and just look at the narrow ‘filler’ stones between the large slabs.
