The poet and visual artist Mina Loy (1882-1966) has long had an underground reputation as an exemplary avant-gardist. Born in London of mixed Jewish and English parentage, and a much photographed beauty, she moved in the pivotal circles of international modernism - in Florence as Gertrude Stein's friend and Marinetti's lover; in New York as Marcel Duchamp's co-conspirator and Djuna Barnes's confidante; in Mexico with her greatest love, the notorious boxer-poet Arthur Cravan; in Paris with the Surrealists and Man Ray. Carolyn Burke's riveting, authoritative biography brings this highly original and representative figure wonderfully alive, in the process giving us a new picture of modernism - and one woman's important contribution to it.
