Io, daughter of Inachus, beloved by Jove, but forced, through the jealous hatred of Juno, to make many wanderings, then appears, and beseeches Prometheus to discover to her what time shall be the limit of her sufferings. Prometheus accedes to her request and relates how she shall wander over many lands and seas until she reaches the city of Canopus, at the mouth of the Nile, where she shall bring forth a Jove-begotten child, from whose seed shall finally spring a dauntless warrior renowned in archery, who will liberate Prometheus from his captivity and accomplish the downfall of Jove.
Io then resumes her wanderings, and Mercury, sent by Jove, comes to question Prometheus as to the nuptials which he has boasted will accomplish the overthrow of the ruler of the Gods. Him Prometheus reviles with opprobrious epithets, calling him a lackey of the Gods, and refuses to disclose anything concerning the matter on which he questions him. The winged God, replying, threatens him with dire calamities. A tempest will come upon him and overwhelm him with thunderbolts, and a bloodthirsting eagle shall feed upon his liver. Thus saying, he departs, and immediately the earth commences to heave, the noise of thunder is heard, vivid streaks of lightning blaze throughout the sky and a hurricane—the onslaught of Jove—sweeps Prometheus away in its blast.
The "Seven against Thebes" includes in its cast of characters Eteocles, King of Thebes, Antigone and Ismene, Sisters of the King, a Messenger and a Herald. The play opens with the siege of Thebes. Eteocles appears upon the Acropolis in the early morning, and exhorts the citizens to be brave and be not over-dismayed at the rabble of alien besiegers. A messenger arrives and announces the rapid approach of the Argives. Eteocles goes to see that the battlements and the gates are properly manned, and during his absence the chorus of Theban maidens set up a great wail of distress and burst forth with violent lamentations. Eteocles, returning, upbraids them severely for their weakness and bids them begone and raise the sacred auspicious shout of the pæan as an encouragement to the Theban warriors. He then departs to prepare himself and six others to meet in combat the seven chieftains who have come against the city.
He soon re-enters, and at the same time comes the messenger from another part of the city with fresh tidings of the foe and the arrangement of the invaders around the walls of the city. By the gate of Prœtus stands the raging Tydeus with his helm of hairy crests and his buckler tricked out with a full moon and a gleaming sky full of stars, against whom Eteocles will marshal the wary son of Astacus, a noble and a modest youth, who detests vain boastings and yet is not a coward.
By the Electron gate is stationed the giant Campaneus, who bears about him the device of a naked man with a gleaming torch in his hands, crying out "I will burn the city." Against him will be pitted the doughty Polyphontes, favored by Diana and other gods.
Against the gate of Neis the mighty Eteoclus is wheeling his foaming steeds, bearing a buckler blazoned with a man in armor treading the steps of a ladder to his foeman's tower. Megareus, the offspring of Creon, is the valiant warrior who will either pay the debt of his nurture to his land or will decorate his father's house with the spoils of the conquered Eteoclus.
The fiery Hippomedon is raging at the gate of Onca Minerva, bearing upon his buckler a Typhon darting forth smoke through his fire-breathing mouth, eager to meet the brave Hyperbius, son of Œnops, who has been selected to check his impetuous onslaught.
At the gate of Boreas the youthful Parthenopæus takes his stand, a fair-faced stripling, upon whose face the youthful down is just making its appearance. Opposed to him stands Actor, a man who is no braggart, but who will not submit to boastful tauntings or permit the rash intruder to batter his way into the city.
The mighty Amphiarus is waiting at the gate of Homolöis, and in the meantime reproaches his ally, Tydeus, calling him a homicide, and Polynices he rebukes with having brought a mighty armament into his native city. Lasthenes, he of the aged mind but youthful form, is the Thebian who has been chosen to marshal his forces against this invader.
At the seventh gate stands Polynices, brother of Eteocles, bearing a well-wrought shield with a device constructed upon it of a woman leading on a mailed warrior, bringing havoc to his paternal city and desirous of becoming a fratricide. Against him Eteocles will go and face him in person, and leader against leader, brother against brother and foeman against foeman, take his stand.
