Theseus is directed by Minerva to leave Ariadne, who sleeps beside him, and proceed to Athens alone. Athens had been compelled for years to send an annual tribute of youths and maidens to Minos, king of Crete, to be devoured by the Minotaur, a savage monster, half bull, half man, who was confined in a Labyrinth. Theseus voluntarily sailed on the tribute-ship, and reaching Crete gained the love of the daughter of Minos, Ariadne, by whose aid he was enabled, after slaying the Minotaur, to find his way out of the Labyrinth. Returning, he bore Ariadne away with him, but deserted her at the island of Naxos, as here depicted, at the command of Minerva. There she was found by Bacchus, who made her his bride. [Illustration: PARIS AND HELEN.--BY WALTER McEWEN.] Achilles, disguised as a maiden, and living among the women of the court of Lycomedes, king of Scyros, is discovered by Ulysses. Thetis, the mother of Achilles, had been forewarned that her son would die an early death, as it turned out afterwards that he did, being slain by Paris before the walls of Troy. She therefore dipped him, while still an infant, in the River Styx. He was thus made invulnerable in every part of his body except his heel, by which his mother had held him, and which therefore remained unaffected by the sacred water. To make assurance doubly sure, Thetis sent him to Lycomedes to be reared as a maiden, far from the dangers of war. When the Greeks were arming for the siege of Troy, the oracle informed them that without Achilles the city could never be taken. The crafty Ulysses was therefore sent in search of him. He arrived at the court of Lycomedes disguised as a pedler, bearing in his basket weapons of war and feminine trinkets. Showing these among the women, all were eager to examine the ornaments; Achilles clutched at the sword and shield, thus discovering himself immediately to the keen eye of Ulysses. Hercules was sold as a slave by Mercury to Omphale, Queen of Lydia. They became enamored of each other, and Hercules, to please her, wore female garments, and spun among the female slaves. The artist here exhibits him aiding the queen in her task. THE HOUSE READING ROOM.
