David Nash works with wood, making interventions in the landscape, such as his Ash Dome canopy fashioned with living trees in the woods at Blaenaeu Ffestiniog where he has lived since 1967 (and where he spent childhood summers). Wooden Boulder was carved in 1978 and left to weather in the Welsh mountains before entering the sea through the river Dwyryd. Nash studied at Kingston, Brighton and Chelsea School of Art and was included in the 1965 New Generation survey exhibition at the Whitechapel Art Gallery in London. His Land Art is firmly rooted in the land, and the wood he uses for his gallery sculpture is always from trees that were felled for woodland conservation and management. He is even said to use twigs to make charcoal. He uses chainsaws to carve rough unpolished forms which are left unvarnished to explore the changing texture of the timber as it ages. Wafer Throne is carved from a beech that grew at Ashton Court. The monumentality of the form is betrayed by the delicate wafer-like slices of the form of the throne.
