“With the War Trilogy and Helen of Egypt, these three poems of H. D.'s late phase bring into print the great works of a poet who is of the same order for me as Ezra Pound or William Carlos Williams: the work of an imagination that incorporates boldly the modern consciousness and aesthetic and the traditional, psychoanalytic realism and hermetic visionary experience.”

— Robert Duncan on Hilda Doolittle (H.D.)'s Hermetic Definition
