dissertation in his _Trilogie_, p. 28; and SCHOEMANN, in the shape of a poetical restoration of the lost poem, in the Appendix to his very valuable edition of this play. About one thing only can we be certain, that, in the ultimate settlement of disputed claims, neither will Prometheus, on the one hand, be degraded from the high position on which the poet has planted him as a sort of umpire between gods and men, nor will Jove yield one whit of his supreme right to exact the bitterest penalties from man or god who presumes to act independently of, and even in opposition to his will. The tragic poet will duly exercise his grand function of keeping the powers of the celestial world--as he does the contending emotions of the human mind--in due equipoise and subordination.[f3] The plot of the Prometheus Unbound is the simplest possible, being not so much the dramatic progression of a course of events, as a single dramatic situation presented through the whole piece under different aspects. The theft of fire from Heaven, or (as the notice of Cicero seems to indicate) from the Lemnian volcano of Mosychlos,[f4] having been perpetrated in the previous piece, MIGHT and FORCE, two allegorical personages, the ministers of Jove's vengeance, are now introduced, along with HEPHAESTUS, the forger of celestial chains, nailing the benevolent offender to a cold craggy rock in the wastes of European Scythia. In this condition when, after a long silence, he at length gives vent to his complaint, certain kindred divine persons--first, the Oceanides, or daughters of Ocean, and then their hoary sire himself, are brought on the scene, with words of solace and friendly exhortation to the sufferer.[f5] When all the arguments that these parties have to advance are exhausted in vain, another mythic personage, of a different character, and for a {182} different purpose, appears. This is Io, the daughter of Inachus, the primeval king of Argos, who, having enjoyed the unblissful distinction of stirring the heart of Jove with love, is, by the jealous wrath of Hera, transmuted into the likeness of a cow[f6] and sent wandering to the ends of the Earth, fretted into restless distraction by the stings of a malignant insect. This character serves a threefold purpose. First, as a sufferer, tracing the origin of all her misery from Jove, she both sympathizes strongly with Prometheus, and exhibits the character of Jove in another unfavourable aspect; secondly, with her wild maniac cries and reinless fits of distraction, she presents a fine contrast to the calm self-possession with which the stout-hearted Titan endures the penalty of his pride; and, in the third place, as the progenitrix of the Argive Hercules, the destined instrument of the delivery of Prometheus, she connects the middle with the concluding piece of the trilogy. Last of all, when this strange apparition has vanished, appears on the scene the great Olympian negotiator, Hermes; who, with the eloquence peculiar to
