(and family) Artist, born in Glasgow, who worked as one of a team, other members of which were Joan Hills, born in Edinburgh in 1936; and the Boyle children: Sebastian, born 1962, and Georgina, born 1964. Mark Boyle after Army service studied law at Glasgow University, 1955–6, then did a variety of jobs such as clerk and waiter. In addition, he put on exhibitions and took part in performance art. In 1964 he and Hills made a replica of a piece of ground, the beginning of a project called The Journey to the Surface of the Earth. The aim of this was to duplicate meticulously 1,000 portions of land, normally about six feet square, chosen by throwing darts at a map. A cast of the section was exactly painted to reproduce it. Boyle aimed at complete objectivity.
