Wyndham Lewis co-founded which short-lived art movement of the 20th century?

Percy Wyndham Lewis (18 November 1882 – 7 March 1957) was an English writer, painter and critic (he dropped the name "Percy", which he disliked). He was a co-founder of the Vorticist movement in art and edited the literary magazine of the Vorticists, BLAST.

Vorticism was a short-lived modernist movement in British art and poetry of the early 20th century, partly inspired by Cubism. The movement was announced in 1914 in the first issue of BLAST, which contained its manifesto and the movement's rejection of landscape and nudes in favour of a geometric style tending towards abstraction.

The Vorticism group began with the Rebel Art Centre which Wyndham Lewis and others established after disagreeing with Omega Workshops founder Roger Fry, and has roots in the Bloomsbury Group, Cubism and Futurism. Lewis himself saw Vorticism as an independent alternative to Cubism, Futurism and Expressionism.

Though the style grew out of Cubism, it is more closely related to Futurism in its embrace of dynamism, the machine age and all things modern. However, Vorticism diverged from Futurism in the way it tried to capture movement in an image. The name Vorticism was given to the movement by Ezra Pound in 1913, although Lewis, usually seen as the central figure in the movement, had been producing paintings in the same style for a year or so previously.
