Shelley's visionary masterwork: a lyrical drama in which Prometheus is finally unchained and the tyrannical Jupiter overthrown, leading to a transformed universe. Together with "Ode to the West Wind," "To a Skylark," and "Adonais" (his elegy for Keats), this volume contains his most sustained achievement. His idealism, his belief that poetry genuinely changes the world, remains either naive or heroic depending on the reader.

The case for it, the case against, and the rest of the canon open with Pro.
