When the surf beat roaring on the strand, Xanthe thought she could hear these creatures guiding their course with their scaly tails and blowing into shells, and many a glimmering foam-crest on a deep-blue wave was no transparent bubble-no, the girl distinctly saw that it was the white neck, the gleaming arm, or the snowy foot of one of Nereus's daughters. She believed that she clearly distinguished them sporting joyously up and down through the azure water, now plunging into the depths with their feet, and now with their heads foremost, anon floating gently on the surface of the waves. One held out her hand to another, and in so doing their beautiful, rounded arms often gleamed beneath the crest of a surge. Every day they practised new games, as the sea never looks precisely the same; each hour it changed its hue, here, there, and everywhere, Light streaks, like transparent bluish-green gauze, often ran through the darker surface, which resembled a purplish-blue mantle of some costly Phoenician stuff; the waves could flash black as the eye of night, and white as Leucothea's neck. Then Amphitrite appeared, with floating hair and resonant voice, and beside her Poseidon with his four steeds. Frowning sullenly, he struck them sharply with his lash, which whistled through the air, and angrily thrust his trident deep into the sea. Instantly the waves took hues of lighter brown, deeper yellow, and cloudy gray, and the sea wore the aspect of a shallow pond with muddy bottom, into which workmen hurl blocks of stone. The purity of the water was sadly dimmed, and the billows dashed foaming toward the sky, threatening in their violent assault to shatter the marble dike erected along the shore. The Nereids, trembling, took refuge in the ever-calm depths, the Tritons no longer used their hollow shells to blow gentle harmonies; nay, they sent forth crashing war-songs, as if some hostile citadel were to be assailed; while Amphitrite thrust both hands into her long, fluttering hair, and with out-stretched head uttered her furious roar. But to-day the sea was calm, and when Xanthe had reached the spring the edges of the milk-white, light, fleecy clouds, towering one above another on the summits of the loftier mountains, were still glowing with a rosy light. It was the edge of the garment of the vanishing Eos, the leaves of the blossoms scattered by the Hours in the pathway of the four steeds of Helios, as they rose from the waves. To day and at this hour the morning sunlight fell serenely on the tall cypresses upon the hill, the trees in the garden swayed in the soft breath of the morning breeze, and Xanthe nodded to them, for she thought the beautiful Dryads living in the trees were greeting each other. Often, with a brief prayer, she laid flowers or a round cake on the altar that stood beside her seat, and which her ancestor had erected to the nymph of the spring--but today she had not come for this.
