This is the largest work made by the artist at a monumental 10m x 3m. Working for nine days at the cliffs in Benllech Bay, McComb observed the connection of the sea, the cliffs, and the sky to capture this profound meeting point of natural energy. Drawn on 84 large sheets of paper, on an easel weighed down with limestone rocks, McComb's insistence on observing from life did not limit the scale of his work. Rendered in pencil, brush and ink, and watercolour, thousands upon thousands of lines depict a dramatic corner of Anglesey as one immutable vibrating mass. The work captures everything that McComb stood for: his philosophy about the natural world, observation from life, and a profound attention to detail. 'Rock and Sea, Anglesey' won the Hugh Casson Prize for Drawing in 2005 at the Royal Academy Summer Show, some 20 years after its creation.
