Often compared with Apollinaire as the first and liveliest avant-garde poet in his language, Vicente Huidobro was a one-man movement ( Creationism ) in the modernist swirl of Paris and Barcelona between the two World Wars. His masterpiece was the 1931 book-length epic Altazor, a Machine Age paean to flight that sends its hero (Altazor, the antipoet ) hurtling through Einsteinian space at light speed. Perhaps the fastest-reading long poem of the century, and certainly the wildest, Altazor rushes through the universe in a lyrical babble of bird-languages, rose-languages, puns, neologisms, and pages of identical rhymes, finally ending in the pure sound of the language of the future. Universally considered untranslatable until the appearance of Eliot Weinberger’s celebrated version in 1988, Altazor appears again in an extensively revised translation with an expanded introduction.
