By juxtaposing several translations of the same passage from Homer; an elegy from Ovid and lines from Herrick that read like an adaptation of Ovid; or a 15th-century poem about a rooster and a contemporary poem about white chickens, Louis Zukofsky has established a means for judging the values of poetic writing. A wonderful education for the fledgling poet, this handbook, first published in 1948, is the best elucidation of Zukofsky"s "objectivist" premises for recognizing value in specific instances of poetry.
