Robinson Jeffers' position as the writer of the most challenging poetry of our time is now generally conceded. The spiritual tragedies that he acts against the rocky landscape of the Pacific coast reveal all the fierce intensity and overwhelming beauty of his unique gifts.  When Roan Stallion, Tamar and Other Poems was first published a new and elemental force in our native poetry was acclaimed. Now, in the Modern Library, it wins new adherents for the poet of the dark labyrinths of the human soul.
