The third painting shows Bellerophon receiving from Minerva a golden bridle with which he may guide the winged horse, Pegasus. The hero had incurred the dislike of his kinsman, Proteus, King of Argos, who sent him with a sealed message to Iobates, King of Lycia. The message desired Iobates to cause Bellerophon to be slain. Being unwilling to do this directly, Iobates sent him to encounter the Chimæra, a horrible monster, part lion, part goat, and part serpent, which was devastating his domains, and which had overpowered all who had ventured to attack it. By the help of Minerva and the winged horse, Bellerophon was successful. Orpheus, who charmed with his song the rocks, the trees, the wild beasts, and even the infernal powers, incurred the wrath of Bacchus, whose divinity he refused to worship. Bacchus therefore inflamed his priestesses, the Mœnads, or Bacchantes, against the poet, who was slain, as here represented by Mr. McEwen, in one of their orgies. Perseus was the son of Jupiter and Danaë. Danaë’s father had heard that his daughter’s son would be the cause of his death. He therefore set the mother and child afloat in the sea in a chest, which was safely cast upon the island of Seriphos, the ruler of which was Polydectes. By the time Perseus had grown to manhood, Polydectes had fallen madly in love with Danaë, and, fearing lest Perseus should be a bar to his passion, he ordered him to cut off the head of the Gorgon Medusa, whose face turned to stone everyone who looked upon it. Assisted by Minerva, Perseus succeeded in his adventure. Returning to Seriphos he found Danaë persecuted by Polydectes, and, appearing at the palace of the king while he and his court were sitting at dinner, he drew the head of Medusa from his wallet and turned the whole company into stone. [Illustration: PROMETHEUS AND PANDORA.--BY WALTER McEWEN.] Prometheus is represented as warning his brother Epimetheus not to accept Pandora from the gods. Prometheus, who, with his brother, was the first of mankind, had outwitted Jupiter in the matter of offering sacrifices; Jupiter, in return, had withheld fire from earth. Prometheus, however, secured it by stealth from heaven, and Jupiter in revenge formed Pandora, the first woman, and sent her to become the bride of Epimetheus. Epimetheus disregarded his brother’s advice and took Pandora and with her the fatal box, which, when opened, let loose a cloud of evils to torment, with only delusive Hope to console, mankind.
