Hercules was the son of Zeus (Jupiter) and Alcmena; but the jealous anger of Hera (Juno) raised up against him an opponent and a master in the person of Eurystheus at whose bidding the greatest of all heroes was to achieve those wonderful labours which filled the whole world with his fame. In these are realized, on a magnificent scale, the two great objects of ancient heroism, the destruction of physical and moral evil, and the acquisition of wealth and power. Such, for instance, are the labours in which he destroys the terrible Nemean lion and Lernean hydra, carries off the girdle of Ares from Hippolyte, queen of the Amazons, and seizes the golden apples of the Hesperides, guarded by a hundred-headed dragon. Theseus was a son of AEgeus, king of Athens, and of AEthra, daughter of Pittheus, king of Troezen. Among his many memorable achievements the most famous was his deliverance of Athens from the frightful tribute imposed upon it by Minos for the murder of his son. This consisted of seven youths and seven maidens whom the Athenians were compelled to send every nine years to Crete, there to be devoured by the Minotaur, a monster with a human body and a bull's head, which Minos kept concealed in an inextricable labyrinth. The third ship was already on the point of sailing with its cargo of innocent victims, when Theseus offered to go with them, hoping to put an end for ever to the horrible tribute. Ariadne, the daughter of Minos, became enamoured of the hero, and having supplied him with a clue to trace the windings of the labyrinth, Theseus succeeded in killing the monster, and in tracking his way out of the mazy lair. Theseus, on his return, became king of Attica, and proceeded to lay the foundations of the future greatness of the country. He united into one political body the twelve independent states into which Cecrops had divided Attica, and made Athens the capital of the new kingdom. He then divided the citizens into three classes, namely, EUPATRIDAE, or nobles; GEOMORI, or husbandmen; and DEMIURGI, or artisans. Minos, king of Crete, whose history is connected with that of Theseus, appears, like him, the representative of an historical and civil state of life. Minos is said to have received the laws of Crete immediately from Zeus; and traditions uniformly present him as king of the sea. Possessing a numerous fleet, he reduced the surrounding islands, especially the Cyclades, under his dominion, and cleared the sea of pirates. The voyage of the Argonauts and the Trojan war were the most memorable enterprises undertaken by collective bodies of heroes.
