In middle age, Walton left Britain and set up home with his young wife Susana on the Italian island of Ischia. By this time, he had ceased to be regarded as a modernist, and some of his compositions of the 1950s were criticised as old-fashioned. His only full-length opera, "Troilus and Cressida", was among the works to be so labelled and has made little impact in opera houses. In his last years, his works came back into critical fashion; his later compositions, dismissed by critics at the time of their premieres, were revalued and regarded alongside his earlier works.
