In his ongoing series Children of Grass, artist B. A. Van Sise photographs American poets who are influenced by Walt Whitman. Each photo is based on a poem—the one below of Nikki Giovanni is inspired by her poem “Allowables”—and a concept developed by Van Sise in collaboration with the poet. Van Sise, who also happens to be one of Whitman’s closest living descendants, hopes to photograph eighty poets, and since he began the project in Spring 2016, he has featured more than twenty-five, including Robert Hass, Rita Dove, Ada Limón, Robert Pinsky, and Cornelius Eady. The project can be viewed on Van Sise’s Instagram account, @b.a.vansise.
