When Opus Posthumous first appeared in 1957, it was an appropriate capstone to the career of one of the most important writers of the twentieth century. It included many poems missing from Stevens's Collected Poems, along with Stevens's characteristically inventive prose and pieces for the theater. Now Milton J. Bates, the author of the acclaimed Wallace Stevens: A Mythology of Self, has edited and revised Opus Posthumous to correct the previous edition's errors and to incorporate material that has come to light since original publication. A third of the poems and essays in this edition are new to the volume. The resulting book is an invaluable literary document whose language and insights are fresh, startling, and eloquent.
