In old heathen times, on the shore of the Adriatic lived a little girl whose greatest pleasure was to wander by the side of the lonely sea. She liked better to sit on a high rock with the spray just tossing against her feet, than to play with her village companions, who laughed at her for her wild ways, and asked her if she were the child of Neptune, and if she dwelt in a shell palace under the water; although they knew very well that old Menos, the fisherman, was her father, and that she lived in a little hut, just above the line of seaweed which the highest tides leave upon the beach. One day Ida roamed far along the beach, amusing herself making deep footprints in the sand, which the rising tide quickly filled, when at last she came upon a high wall of rock, too steep to climb, yet looking as if a pleasant bay might be beyond. She scrambled along the rock, slippery with seaweed, until she could peep round into a great cave, before which was a little beach of smooth, white sand, with dark, frowning rocks all around, except where the sea broke gently in upon it. In the darkness of the cave an old woman leaned over a book. Its brilliant cover attracted Ida, who, half in fear, stole nearer and nearer, treading so softly in the sand that her foot-steps could not be heard, and at last seated herself in the shadow by the old woman, and listened to the wonderful stories which she read, in a low, murmuring voice. “High upon Olympus, on his golden throne, the blue sky shines above him, and around stand the immortals;” and then, mingled with the sound of the waves, came songs from Apollo's lyre, and descriptions of Bacchus, drawn by his soft-footed leopards, of Venus and her snowy doves, of fauns and nymphs, and wondrous people, of whom Ida had never before heard. She listened until the sun set and night darkened upon the waters, then slowly retraced her way home, thinking every cloud that floated above her might be a messenger from Olympus, and that every fleck of foam was perhaps the little white hand of a nereid, sporting amid the waves.
