His varied output of sculptures, illustrations, poems and stories reveals an obsession with flight, myths, mirrors and mazes. He was a stage and costume designer, working with John Minton on the 1942 John Gielgud production of Macbeth at the age of nineteen. And a book designer and illustrator, for Wyndham Lewis's The Human Age trilogy.
An exhibition, 'Word and Image' (National Book League 1971), organised with Wyndham Lewis, explored their literary and artistic connections. He also collaborated with Constant Lambert and William Golding. Ayrton was born Michael Gould, son of the writer Gerald Gould and the Labour politician Barbara Ayrton, and took his mother's maiden name professionally.
In his teens during the 1930s he studied art at Heatherley School of Fine Art and St John's Wood Art School, then in Paris under Eugène Berman, where he shared a studio with John Minton. He travelled to Spain and attempted to enlist on the Republican side in the Spanish Civil War, but was rejected for being under-age. Beginning in 1961, Michael Ayrton wrote and created many works associated with the myths of the Minotaur and Daedalus, the legendary inventor and maze builder, including bronze sculpture and the pseudo-autobiographical novel "The Maze Maker" (Holt, Rinehart and Winston, 1967).
He also wrote and illustrated "Tittivulus Or The Verbiage Collector", an account of the efforts of a minor devil to collect idle words. He was the author of several non-fiction works on fine art, including "Aspects of British Art" (Collins, 1947). He died in 1975. In 1977, Birmingham Museum and Art Gallery organised a major retrospective exhibition of his work which subsequently went on tour.
His work is in several important collections including the Tate Gallery, London, National Portrait Gallery, London, Museum of Modern Art, New York, Fry Art Gallery, Essex.
