Prometheus Bound has been one of the most influential of the classical Greek tragedies, inspiring poems by Goethe, Shelly, Byron and others. But it is often misunderstood, because it is read in isolation. Read by itself, Prometheus Bound seems to tell the story of Prometheus' heroic resistance to Zeus' tyranny. But when we read the entire trilogy, we can see that the relation between Zeus and Prometheus is far more complex. Prometheus Bound has always been considered one of the greatest Greek tragedies - and this book lets us see that the Prometheus trilogy as a whole is more powerful than this one play. This edition uses Henry David Thoreau's translation of Prometheus Bound, published in 1843 in The Dial magazine, the most making it available to a wide audience in book form for the first time. This edition also includes an introduction by the great classical scholar, Nikolaus Wecklein, which has long been out of print, and also includes commentary by Charles Siegel, which makes an important new contribution to scholars' attempts to reconstruct the Prometheus trilogy.This second edition is an expanded version of the first edition, published in 2015.
