This painting is my contribution to an exhibition at Gray's Inn, London, commemorating the 800th anniversary of the Magna Carta. My subject is the Ankerwycke Yew, 2500 years old growing by Runnymede and alleged to be the spot where the Magna Carta was signed. My idea is to portray this tree with one canvas showing the branches like a gilded cage, and the other canvas nearly filled by the bulky trunk. This is to reflect the dual nature of the Magna Carta as both restricting (for the King) and protective (for the people). I have painted it in oil and mixed media on two small square canvases, butted up and framed together as a diptych, the total size being 65 x 35 cm.
