MADRID.- Wyndham Lewis could be described as a “single-handed avant-garde movement”. An accomplished artist, Lewis founded Vorticism, the only English avant-garde movement, and was the author of more than 50 books. In addition he issued manifestoes, edited and published journals and was responsible for a fascinating and strikingly varied body of work that runs from his vorticist, Cubo-futurist and abstract compositions to his most refined portraits. Surprisingly, however, “the most fascinating personality of our time”, as T. S. Eliot wrote in 1918, and “the greatest portraitist of this or any other time”, as Walter Sickert hailed him in 1932, is still largely unknown to the general public. A pioneer of abstraction, war artist, major portraitist, novelist, essayist, editor and critic, Wyndham Lewis is one of the key figures in European modernism of the first half of the 20th
