Stone 15a, West Kennet Avenue - (November 2024)

The eye of this figure appears to me to be based around a natural roothole in the sarsen. This hole has been artificially expanded by the artist, creating a "terraced" effect in the outer eye socket (see the larger version of the image for this).  The left profile of the monolith has then been chipped away to create the sculpted face profile. (By the way, you can see an eye constructed in a similar way on Stone 10 here).
