Ovid
The Metamorphoses of Ovid, Book VII (Fable. 4)
Hercules chains the dog Cerberus, the guardian of the gates of the Infernal Regions. Theseus, after his exploits at Corinth, arrives at Athens, where Medea prepares a cup of poison for him. The king, however, recognizing his son, just as he is about to drink, snatches away the cup from him, while Medea flies in her chariot. Ægeus then makes a festival, to celebrate the arrival and preservation of Theseus. In the mean time, Minos, the king of Crete, solicits several princes to assist him in a war against Athens, to revenge the death of his son Androgeus, who had been murdered there.

Ægeus, to be blamed for this deed alone, shelters her; and hospitality is not enough, he also joins her to himself by the ties of marriage. And now was Theseus, his son, arrived, unknown to his father, who, by his valor, had established peace in the Isthmus between the two seas. For his destruction Medea mingles the wolfsbane, which she once brought with her from the shores of Scythia. This, they say, sprang from the teeth of the Echidnean dog. There is a gloomy cave,74 with a dark entrance, wherein there is a descending path, along which the Tirynthian hero dragged away Cerberus resisting, and turning his eyes sideways from the day and the shining rays of the Sun, in chains formed of adamant; he, filled with furious rage, filled the air with triple barkings at the same moment, and sprinkled the verdant fields with white foam. This, they suppose, grew solid, and, receiving the nourishment of a fruitful and productive soil, acquired the power of being noxious. Because, full of life, it springs up on the hard rock, the rustics call it aconite.75

This, by the contrivance of his wife, the father Ægeus himself presented to his son,76 as though to an enemy. Theseus had received the presented cup with unsuspecting right hand, when his father perceived upon the ivory hilt of his sword the tokens of his race,77 and struck the guilty draught from his mouth. She escaped death, having raised clouds by her enchantments.

But the father, although he rejoices at his son’s being safe, astonished that so great a wickedness can be committed with so narrow an escape from death, heats the altars with fires, and loads the Gods with gifts; and the axes strike the muscular necks of the oxen having their horns bound with wreaths. No day is said ever to have shone upon the people of Erectheus more famous than that—the senators and the common people keep up the festivity; songs, too, they sing, wine inspiring wit. “Thee, greatest Theseus,” said they, “Marathon78 admired for shedding the blood of the Cretan bull; and that the husbandman ploughs Cromyon79 in safety from the boar, is thy procurement and thy work. By thy means the country of Epidaurus saw the club-bearing son of Vulcan80 fall; and the banks of the river Cephisus81 saw the cruel Procrustes fall by thee. Eleusis, sacred to Ceres, beheld the death of Cercyon.82 Sinnis83 fell too, who barbarously used his great powers; who was able to bend huge beams, and used to pull pine trees from aloft to the earth, destined to scatter human bodies far and wide. The road to Alcathoë,84 the Lelegeïan city, is now open in safety, Scyron85 being laid low in death: and the earth denies a resting-place, the water, too, denies a resting-place to the bones of the robber scattered piecemeal; these, long tossed about, length of time is reported to have hardened into rocks. To these rocks the name of Scyron adheres. If we should reckon up thy glorious deeds, and thy years, thy actions would exceed thy years in number. For thee, bravest hero, we make public vows: in thy honor do we quaff the draughts of wine.” The palace rings with the acclamations of the populace, and the prayers of those applauding; and there is no place sorrowing throughout the whole city.

And yet (so surely is the pleasure of no one unalloyed, and some anxiety is ever interposing amid joyous circumstances), Ægeus does not have his joy undisturbed, on receiving back his son. Minos prepares for war; who, though he is strong in soldiers, strong in shipping, is still strongest of all in the resentment of a parent, and, with retributive arms, avenges the death of his son Androgeus. Yet, before the war, he obtains auxiliary forces, and crosses the sea with a swift fleet, in which he is accounted strong. On the one side, he joins Anaphe86 to himself; and the realms of Astypale; Anaphe by treaty, the realms of Astypale by conquest; on the other side, the low Myconos, and the chalky lands of Cimolus,87 and the flourishing Cythnos, Scyros, and the level Seriphos;88 Paros, too, abounding in marble, and the island wherein the treacherous Sithonian89 betrayed the citadel, on receiving the gold, which, in her covetousness, she had demanded. She was changed into a bird, which even now has a passion for gold, the jackdaw namely, black-footed, and covered with black feathers.

Footnotes:

74. A gloomy cave.]—Ver. 409. This cavern was called Acherusia. It was situate in the country of the Mariandyni, near the city of Heraclea, in Pontus, and was said to be the entrance of the Infernal Regions. Cerberus was said to have been dragged from Tartarus by Hercules, through this cave, which circumstance was supposed to account for the quantity of aconite, or wolfsbane, that grew there.

75. Call it aconite.]—Ver. 419. From the Greek ακόνη, ‘a whetstone.’

76. Presented to his son.]—Ver. 420. Medea was anxious to secure the succession to the throne of Athens to her son Medus, and was therefore desirous to remove Theseus out of the way.

77. Tokens of his race.]—Ver. 423. Ægeus, leaving Æthra at Trœzen, in a state of pregnancy, charged her, if she bore a son, to rear him, but to tell no one whose son he was. He placed his own sword and shoes under a large stone, and directed her to send his son to him when he was able to lift the stone, and to take them from under it; and he then returned to Athens, where he married Medea. When Theseus had grown to the proper age, his mother led him to the stone under which his father had deposited his sword and shoes, which he raised with ease, and took them out. It was, probably, by means of this sword that Ægeus recognized his son in the manner mentioned in the text.

78. Marathon.]—Ver. 434. This was a town of Attica, adjoining a plain of the same name, where the Athenians, under the command of Miltiades, overthrew the Persians with immense slaughter. The bull which Theseus slew there was presented by Neptune to Minos. Being brought into Attica by Hercules, it laid waste that territory until it was slain by Theseus.

79. Cromyon.]—Ver. 435. This was a village of the Corinthian territory, which was infested by a wild boar of enormous size, that slew both men and animals. It was put to death by Theseus.

80. Vulcan.]—Ver. 437. By Antilia, Vulcan was the father of Periphetes, a robber who infested Epidaurus, in the Peloponnesus. He was so formidable with his club, that he was called Corynetas, from κορύνη, the Greek for ‘a club.’
81. Cephisus.]—Ver. 438. Procrustes was a robber of such extreme cruelty that he used to stretch out, or lop off, the extremities of his captives, according as they were shorter or longer than his bedstead. He infested the neighborhood of Eleusis, in Attica, which was watered by the Cephisus. He was put to death by Theseus.

82. Cercyon.]—Ver. 439. It was his custom to challenge travellers to wrestle, and to kill them, if they declined the contest, or were beaten in it. Theseus accepted his challenge; and having overcome him, put him to death. Eleusis was especially dedicated to Ceres; there the famous Eleusinian mysteries of that Goddess were held.

83. Sinnis.]—Ver. 440. He was a robber of Attica, to whom reference is made in the Ibis, line 409.

84. Alcathoë.]—Ver. 443. Megara, or Alcathoë, which was founded by Lelex, was almost destroyed by Minos, and was rebuilt by Alcathoüs, the son of Pelops. He, flying from his father, on being accused of the murder of his brother Chrysippus, retired to the city of Megara, where, having slain a lion which was then laying waste that territory, he was held in the highest veneration by the inhabitants.

85. Scyron.]—Ver. 443. This robber haunted the rocks in the neighborhood of Megara, and used to insist on those who became his guests washing his feet. This being done upon the rocks, Scyron used to kick the strangers into the sea while so occupied, where a tortoise lay ready to devour the bodies. Theseus killed him, and threw his body down the same rocks, which derived their name of Saronic, or Scyronic, from this robber.

86. Anaphe.]—Ver. 461. This, and the other islands here named, were near the isle of Crete, and perhaps in those times were subject to the sway of Minos.

87. Cimolus.]—Ver. 463. Pliny the Elder tells us, that this island was famous for producing a clay which seems to have had much the properties of soap. It was of a grayish white color, and was also employed for medicinal purposes.

88. Seriphos.]—Ver. 464. Commentators are at a loss to know why Seriphos should here have the epithet ‘plana,’ ‘level,’ inasmuch as it was a very craggy island. It is probably a corrupt reading.
