Across my line of vision, moving stately over the sea, floated a half globe, luminous, diaphanous, its iridescence melting into turquoise, thence to amethyst, to orange, to scarlet shot with rose, to vermilion, a translucent green, thence back into the iridescence; behind it four others, and the least of them ten feet in diameter, and the largest no less than thirty. They drifted past like bubbles blown from froth of rainbows by pipes in mouths of Titans’ young. Then from the base of one arose a tangle of shimmering strands, long, slender whiplashes that played about and sank slowly again beneath the crimson surface.
