The sound revealed that the horse was hollow, but the Trojans heeded not this warning of possible fraud. The unfortunate Laocoon, a victim to his own sagacity and patriotism, miserably perished before the eyes of his countrymen, together with one of his sons: two serpents being sent expressly by the gods out of the sea to destroy him. By this terrific spectacle, together with the perfidious counsels of Simon—a traitor whom the Greeks had left behind for the special purpose of giving false information—the Trojans were induced to make a breach in their own walls, and to drag the fatal fabric with triumph and exultation into their city.

The destruction of Troy, according to the decree of the gods, was now irrevocably sealed. While the Trojans indulged in a night of riotous festivity, Simon kindled the fire-signal to the Greeks at Tenedos, loosening the bolts of the wooden horse, from out of which the enclosed heroes descended. The city, assailed both from within and from without, was thoroughly sacked and destroyed, with the slaughter or captivity of the larger portion of its heroes as well as its people. The venerable Priam perished by the hand of Neoptolemus, having in vain sought shelter at the domestic altar of Zeus Herceius. But his son Deiphobus, who since the death of Paris had become the husband of Helen, defended his house desperately against Odysseus and Menelaus, and sold his life dearly. After he was slain, his body was fearfully mutilated by the latter.

Thus was Troy utterly destroyed—the city, the altars and temples, and the population. Æneas and Antenor were permitted to escape, with their families, having been always more favorably regarded by the Greeks than the remaining Trojans. According to one version of the story they had betrayed the city to the Greeks: a panther's skin had been hung over the door of Antenor's house as a signal for the victorious besiegers to spare it in general plunder. In the distribution of the principal captives, Astyanax, the infant son of Hector, was cast from the top of the wall and killed by Odysseus or Neoptolemus: Polyxena, the daughter of Priam, was immolated on the tomb of Achilles, in compliance with a requisition made by the shade of the deceased hero to his countrymen; while her sister Cassandra was presented as a prize to Agamemnon. She had sought sanctuary at the altar of Athene, where Ajax, the son of Oileus, making a guilty attempt to seize her, had drawn both upon himself and upon the army the serious wrath of the goddess, insomuch that the Greeks could hardly be restrained from stoning him to death. Andromache and Helenus were both given to Neoptolemus, who, according to the Ilias Minor, carried away also Æneas as his captive.

Helen gladly resumed her union with Menelaus; she accompanied him back to Sparta, and lived with him there many years in comfort and dignity, passing afterward to a happy immortality in the Elysian fields. She was worshipped as a goddess, with her brothers, the Dioscuri, and her husband, having her temple, statue, and altar at Therapnæ and elsewhere. Various examples of her miraculous intervention were cited among the Greeks. The lyric poet Stesichorus had ventured to denounce her, conjointly with her sister Clytemnestra, in a tone of rude and plain-spoken severity, resembling that of Euripides and Lycophron afterward, but strikingly opposite to the delicacy and respect with which she is always handled by Homer, who never admits reproaches against her except from her own lips. He was smitten with blindness, and made sensible of his impiety; but, having repented and composed a special poem formally retracting the calumny, was permitted to recover his sight. In his poem of recantation (the famous Palinode now unfortunately lost) he pointedly contradicted the Homeric narrative, affirming that Helen had never been at Troy at all, and that the Trojans had carried thither nothing but her image or eidolon. It is, probably, to the excited religious feelings of Stesichorus that we owe the first idea of this glaring deviation from the old legend, which could never have been recommended by any considerations of poetical interest.

Other versions were afterward started, forming a sort of compromise between Homer and Stesichorus, admitting that Helen had never really been at Troy, without altogether denying her elopement. Such is the story of her having been detained in Egypt during the whole term of the siege. Paris, on his departure from Sparta, had been driven thither by storms, and the Egyptian king Proteus, hearing of the grievous wrong which he had committed toward Menelaus, had sent him away from the country with severe menaces, detaining Helen until her lawful husband should come to seek her. When the Greeks reclaimed Helen from Troy, the Trojans assured them solemnly that she neither was nor ever had been in the town; but the Greeks, treating this allegation as fraudulent, prosecuted the siege until their ultimate success confirmed the correctness of the statement. Menelaus did not recover Helen until, on his return from Troy, he visited Egypt. Such was the story told by the Egyptian priests to Herodotus, and it appeared satisfactory to his historicizing mind. "For if Helen had really been at Troy," he argues, "she would certainly have been given up, even had she been mistress of Priam himself instead of Paris: the Trojan king, with all his family and all his subjects, would never knowingly have incurred utter and irretrievable destruction for the purpose of retaining her: their misfortune was that, while they did not possess and therefore could not restore her, they yet found it impossible to convince the Greeks that such was the fact." Assuming the historical character of the war of Troy, the remark of Herodotus admits of no reply; nor can we greatly wonder that he acquiesced in the tale of Helen's Egyptian detention, as a substitute for the "incredible insanity" which the genuine legend imputes to Priam and the Trojans. Pausanias, upon the same ground and by the same mode of reasoning, pronounced that the Trojan horse must have been, in point of fact, a battering-engine, because to admit the literal narrative would be to impute utter childishness to the defenders of the city. And Mr. Payne Knight rejects Helen altogether as the real cause of the Trojan war, though she may have been the pretext of it; for he thinks that neither the Greeks nor the Trojans could have been so mad and silly as to endure calamities of such magnitude "for one little woman." Mr. Knight suggests various political causes as substitutes; these might deserve consideration, either if any evidence could be produced to countenance them, or if the subject on which they are brought to bear could be shown to belong to the domain of history.

The return of the Grecian chiefs from Troy furnished matter to the ancient epic hardly less copious than the siege itself, and the more susceptible of indefinite diversity, inasmuch as those who had before acted in concert were now dispersed and isolated. Moreover, the stormy voyages and compulsory wanderings of the heroes exactly fell in with the common aspirations after an heroic founder, and enabled even the most remote Hellenic settlers to connect the origin of their town with this prominent event of their ante-historical and semi-divine world. And an absence of ten years afforded room for the supposition of many domestic changes in their native abode, and many family misfortunes and misdeeds during the interval. One of these historic "Returns," that of Odysseus, has been immortalized by the verse of Homer. The hero, after a series of long protracted suffering and expatriation inflicted on him by the anger of Poseidon, at last reaches his native island, but finds his wife beset, his youthful son insulted, and his substance plundered by a troop of insolent suitors; he is forced to appear as a wretched beggar, and to endure in his own person their scornful treatment; but finally, by the interference of Athene coming in aid of his own courage and stratagem, he is enabled to overwhelm his enemies, to resume his family position, and to recover his property. The return of several other Grecian chiefs was the subject of an epic poem by Hagias which is now lost, but of which a brief abstract or argument still remains: there were in antiquity various other poems of similar title and analogous matter.

As usual with the ancient epic, the multiplied sufferings of this back voyage are traced to divine wrath, justly provoked by the sins of the Greeks, who, in the fierce exultation of a victory purchased by so many hardships, had neither respected nor even spared the altars of the gods in Troy. Athene, who had been their most zealous ally during the siege, was so incensed by their final recklessness, more especially by the outrage of Ajax, son of Oileus, that she actively harassed and embittered their return, in spite of every effort to appease her. The chiefs began to quarrel among themselves; their formal assembly became a scene of drunkenness; even Agamemnon and Menelaus lost their fraternal harmony, and each man acted on his own separate resolution. Nevertheless, according to the Odyssey, Nestor, Diomedes, Neoptolemus, Idomeneus, and Philoctetes reached home speedily and safely; Agamemnon also arrived in Peloponnesus, to perish by the hand of a treacherous wife; but Menelaus was condemned to long wanderings and to the severest privations in Egypt, Cyprus, and elsewhere before he could set foot in his native land. The Locrian Ajax perished on the Gyræan rock. Though exposed to a terrible storm, he had already reached this place of safety, when he indulged in the rash boast of having escaped in defiance of the gods. No sooner did Poseidon hear this language than he struck with his trident the rock which Ajax was grasping and precipitated both into the sea. Calchas, the soothsayer, together with Leonteus and Polypoetes, proceeded by land from Troy to Colophon.

In respect, however, to these and other Grecian heroes, tales were told different from those in the Odyssey, assigning to them a long expatriation and a distant home. Nestor went to Italy, where he founded Metapontum, Pisa, and Heracleia: Philoctetes also went to Italy, founded Petilia and Crimisa, and sent settlers to Egesta in Sicily. Neoptolemus, under the advice of Thetis, marched by land across Thrace, met with Odysseus, who had come by sea, at Maroneia, and then pursued his journey to Epirus, where he became king of the Molossians. Idomeneus came to Italy, and founded Uria in the Salentine peninsula. Diomedes, after wandering far and wide, went along the Italian coast into the innermost Adriatic gulf, and finally settled in Daunia, founding the cities of Argyrippa, Beneventum, Atria, and Diomedeia: by the favor of Athene he became immortal, and was worshipped as a god in many different places. The Locrian followers of Ajax founded the Epizephyrian Locri on the southernmost corner of Italy, besides another settlement in Libya.

The previously exiled Teucros, besides founding the city of Salamis in Cyprus, is said to have established some settlements in the Iberian peninsula. Menestheus, the Athenian, did the like, and also founded both Elæa in Mysia and Scylletium in Italy. The Arcadian chief Agapenor founded Paphos in Cyprus. Epius, of Panopeus in Phocis, the constructor of the Trojan horse with the aid of the goddess Athene, settled at Lagaria, near Sybaris, on the coast of Italy; and the very tools which he had employed in that remarkable fabric were shown down to a late date in the temple of Athene at Metapontum.

Temples, altars, and towns were also pointed out in Asia Minor, in Samos, and in Crete, the foundation of Agamemnon or of his followers. The inhabitants of the Grecian town of Scione, in the Thracian peninsula called Pallene or Pellene, accounted themselves the offspring of the Pellenians from Achæa in Peloponnesus, who had served under Agamemnon before Troy, and who on their return from the siege had been driven on the spot by a storm and there settled. The Pamphylians, on the southern coast of Asia Minor, deduced their origin from the wanderings of Amphilochus and Calchas after the siege of Troy: the inhabitants of the Amphilochian Argos on the Gulf of Ambracia revered the same Amphilochus as their founder. The Orchomenians under Iamenus, on quitting the conquered city, wandered or were driven to the eastern extremity of the Euxine Sea; and the barbarous Achæans under Mount Caucasus were supposed to have derived their first establishment from this source. Meriones, with his Cretan followers, settled at Engyion in Sicily, along with the preceding Cretans who had remained there after the invasion of Minos. The Elymians in Sicily also were composed of Trojans and Greeks separately driven to the spot, who, forgetting their previous differences, united in the joint settlements of Eryx and Egesta. We hear of Podalerius both in Italy and on the coast of Caria; of Acamas, son of Theseus, at Amphipolus in Thrace, at Soli in Cyprus, and at Synnada in Phrygia; of Guneus, Prothous, and Eurypylus, in Crete as well as in Libya. The obscure poem of Lycophron enumerates many of these dispersed and expatriated heroes, whose conquest of Troy was indeed a "Cadmean" victory (according to the proverbial phrase of the Greeks), wherein the sufferings of the victor were little inferior to those of the vanquished. It was particularly among the Italian Greeks, where they were worshipped with very special solemnity, that their presence as wanderers from Troy was reported and believed.
