Breon O'Casey has been a highly productive and much-respected artist for four decades but his public reputation has only recently spread beyond certain interlocked art and craft circles. He has been a jeweller, a painter, an etcher, a weaver, and more recently he has taken to sculpture. Although his gold and silver jewellery has won him an international reputation with connoisseurs and his hand woven creations have been targeted by knowledgeable collectors, he now concentrates on painting, sculpture and graphic work.
The son of the playwright Sean O'Casey, for most of his career Breon O'Casey has lived in Cornwall and has been closely associated with the St Ives School of painters and sculptors. An apprenticeship to the sculptors Denis Mitchell and Barbara Hepworth confirmed his feeling for materials and for working with his hands. He also benefited from his friendships with other leading artists, such as Peter Lanyon, John Wells and Tony O'Malley.
