In rebellion against romanticism, the modernists attempted to renew poetic language and to create a poetry characterized by formal perfection, musicality, and strongly evocative imagery. Cesar Vallejo's Trilce, published in 1922, was at the forefront of  the avant-garde movement that would develop in the 1920s and 1930s. Vallejo's poetry stretched syntax, invented words, and deployed automatic writing and other techniques now known as "surrealist".
