A deluxe edition of Whitman's crowning achievement, with an introductory essay by Harold Bloom I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. When Walt Whitman self-published his Leaves of Grass in July 1855, he altered the course of literary history. One of the greatest masterpieces of American literature, it redefined the rules of poetry while describing the soul of the American character.
