son-in-law was eager to avenge his brothers' murder, and having sought out the wicked Danaüs, fulfilled the prophecy by killing the king with the very dagger intended for his own death. The gods punished the cruel daughters--except Hypermnestra, who had saved her husband--by condemning them to labor in Tartarus at their impossible task. Near the Danaïdes stands Tantalus, the father of Niobe, who on earth was a most inhuman and brutal king. He ill-treated his subjects, defied the gods, and dared to make his own will the religion of his kingdom. He boasted that the gods were not so omniscient as people were led to believe; and insulted the immortals by offering them at a banquet the flesh of his own son Pelops, believing that they would never learn the truth of this loathsome feast. But the gods were not deceived, and left the meal untouched,--all except poor Ceres, who, still mourning over her daughter's detention in Hades, did not realize what was happening and bit off some of the lad's shoulder. When the gods restored Pelops to life, Ceres was very sorry for her carelessness and gave him a shoulder of ivory. The inhuman Tantalus was condemned to the torments of Tartarus, where he stands up to his chin in a clear stream. Though frenzied with thirst he can never drink of the water, for whenever he bends his head the stream recedes from his parched lips. Above him hangs a branch of delicious fruit; but when, tormented with hunger, he strives to grasp it, the branch eludes his eager fingers. Thus he stays, always "tantalized" by the sight of food and drink he never can secure. Not far from Tantalus is Salmoneus, also a king, who dared to challenge the gods by impersonating Jupiter. He made a huge bridge of brass, and drove heavily over it while he threw lighted torches among the people who were waiting below, hoping thus to frighten them into believing that he was the very ruler of the heavens who hurls the mighty thunderbolts. This insult to his divinity so angered Jupiter that he seized a real thunderbolt and soon dispatched the arrogant king. When Salmoneus came before the throne of Pluto, his fate was quickly decided, and he was driven to terrible Tartarus, where he sits under a huge rock that threatens every moment to fall and crush him beneath its weight. Another unhappy king is Sisyphus, who, when ruler of Corinth, became a famous robber, and in the pride of his great wealth dared to set the gods at naught. Therefore he was consigned to Tartarus, and his punishment is to roll an immense stone to the top of a steep hill. As soon as he reaches the summit, the rock slips from his aching arms and tumbles to the foot of the hill, and he must at once start on the hopeless task of pushing it up the long ascent again. "With many a weary step, and many a groan, Up the high hill he heaves a huge round stone." --HOMER--Pope's translation.
