That Jupiter himself, though wedded to the goddess Juno, should be charged with numerous other love affairs, not only in respect of goddesses but of mortals, is, in part, explained by the fact that to the supreme divinity of the Greeks have been ascribed attributes and adventures of numerous local and foreign divinities that were gradually identified with him. It is, therefore, not wise to assume that the love affairs of Jupiter and of other divinities always symbolize combinations of natural or physical forces that have repeated themselves in ever-varying guise. It is important to understand that the more ideal Olympian religion absorbed features of inferior religions, and that Jupiter, when represented as appropriating the characteristics of other gods, was sometimes, also, accredited with their wives. Beside the children of Jupiter already enumerated, there should here be mentioned, as of peculiar consequence, Bacchus (Dionysus), the god of wine, a deity of earth,--Proserpine, the wife of Pluto and queen of the underworld,--and Hercules, the greatest of the heroes. [Illustration: FIG. 8. ZEUS AFTER PHIDIAS] =25. Conceptions of Jupiter.= The Greeks usually conceived the Jupiter of war as riding in his thunder-car, hurling the thunderbolt or lashing his enemies with a scourge of lightning. He wore a breastplate or shield of storm-cloud like the skin of a gray goat (the _Ægis_), fearful to behold, and made by the god of fire. His special messenger was the eagle. It was, however, only with the passage of generations that the Greeks came to represent their greatest of the gods by the works of men's hands. The statue of Olympian Jove by Phidias was considered the highest achievement of Grecian sculpture. It was of colossal dimensions and, like other statues of the period, "chryselephantine," that is, composed of ivory and gold. For the parts representing flesh were of ivory laid on a framework of wood, while the drapery and ornaments were of gold. The height of the figure was forty feet, of the pedestal twelve. The god was represented as seated on his throne. His brows were crowned with a wreath of olive; he held in his right hand a scepter, and in his left a statue of Victory. The throne was of cedar, adorned with gold and precious stones. The idea which the artist essayed to embody was that of the supreme deity of the Hellenic race, enthroned as a conqueror, in perfect majesty and repose, and ruling with a nod the subject world. Phidias informs us that the idea was suggested by Homer's lines in the first book of the Iliad: Jove said, and nodded with his shadowy brows; Waved on th' immortal head th' ambrosial locks,-- And all Olympus trembled at his nod.[23] Unfortunately, our knowledge of this famous statue is confined to literary descriptions, and to copies on coins. Other representations of Jove have been obtained from Greek bronze statuettes, or the wall-paintings of Herculaneum and Pompeii.
