The Negro Speaks of Rivers by Langston Hughes

The critic Donald B. Gibson noted in the introduction to Modern Black Poets: A Collection of Critical Essays (Prentice Hall, 1973) that Hughes “differed from most of his predecessors among black poets… in that he addressed his poetry to the people, specifically to black people. During the twenties when most American poets were turning inward, writing obscure and esoteric poetry to an ever decreasing audience of readers, Hughes was turning outward, using language and themes, attitudes and ideas familiar to anyone who had the ability simply to read... Until the time of his death, he spread his message humorously—though always seriously—to audiences throughout the country, having read his poetry to more people (possibly) than any other American poet.”
