The divinities who dwelt in the Cave of Sleep were distrusted by the ancients, and Mors was held in universal dread. No homage was ever offered to him, and no temples were dedicated in his honor; though sacrifices were sometimes made to ward off his dreaded coming. He was never represented in art except in a pleasing aspect, for although they believed him to have in reality the fearful appearance that tradition ascribed to him, yet the beauty-loving Greeks refused to have this kind of horror embodied in marble. So when Death appears in sculpture, it is usually with his brother Sleep, and both are represented as sleeping youths, whose heads are crowned with poppies or amaranths, and who hold inverted torches in their listless hands. Chapter XVIII Neptune and the Sea-Gods I In the days when the Titans ruled the universe, Oceanus, with his wife Tethys, controlled all the lakes, rivers, and seas; but when the Titans were overthrown, Neptune took possession of this great kingdom, and old Oceanus reluctantly gave up his dominion over the waters of the earth. Though anxious to assert his supreme authority, Neptune allowed some of the descendants of the Titans to keep their small kingdoms, on condition that they own allegiance to him as their ruler. Among these was Nereus, son of Oceanus, who was celebrated for his vast knowledge, his gift of prophecy, and his love of truth and justice. He and his wife Doris (also a child of Oceanus) had fifty daughters called Nereids,[47] and they were so beautiful that Neptune chose one of them, named Amphitrite, for his wife. There were two others of the Nereids who became famous: Galatea, beloved by the Cyclops Polyphemus,[48] and Thetis, the mother of Achilles; but none of them equaled Amphitrite in beauty. [Illustration: Fountain of Neptune] When Neptune first went wooing the Nereid, she was frightened by his formidable appearance, for he drove in a chariot drawn by huge sea-horses with brazen hoofs and golden manes; and the god himself carried his terrible trident, or three-pronged spear, with which he shatters rocks, and commands the storms, and shakes the shores of earth. None knew better than Amphitrite the extent of Neptune's power, for she had often watched him, when a storm was at its height, raise his all-compelling trident, and immediately the waves would cease raging and there would be a great calm. Sometimes she saw a ship, doomed by the sea-god to disaster, gliding confidently in quiet waters, when all at once a fierce storm would break over its head; and the hapless sailors, as they breasted the angry waves, would pray vainly to Neptune for the help that would never come. Many a good ship had nearly gained her port when
