Without beginning or end

Lines composed at the siting of Richard Long's outdoor sculpture MacDuff's Circle at Mod 2 Edinburgh ( National Museum of Modern Art). I was struck by the triangle that connected 3 very different circles at its location - looking across from the perfect circle ( without beginning or end) of the sculpture connecting with the formal classical monument of James Buchanan in the adjacent Deans Cemetery and then the immediacy of the mature Copper Beech tree on its rounded grass mound.
