In this chapter Peter Barry explores poems about stones, on stones and as stones. He shows how our ancestors had a special regard for stones particularly those that seemed out of place, such as glacial erratics. The Ringing Stone on Tiree is one such, bearing numerous cup marks from Neolithic times. He considers how poems have been placed in the environment on trails and paths, sometimes with a didactic purpose as part of an environmentalist interpretive scheme. Some of these have taken advantage of the expressive potential of the stones themselves, and of letter carvers who blend this with their own artistic heritage. Collaborations between carver and poet can make best use of the space between the words that come closest to Barry’s interest in avant-gardeorneo-modernist poetry(especially ‘concrete’ and ‘visual’ poetries). Barry also considers poems in urban settings, in projects involving close collaboration with councils, NGOs and communities, where the words have been incised on bridges, monuments, paths, or pavements, as by Alyson Hallett in Bath, Lemn Sissay in Manchester, Bill Herbert near Darlington, and Menna Elfyn and Gillian Clarke in Tonypandy.
