A Sea-Spell

(For one of his own pictures) Her lute hangs shadowed in the apple-tree, While flashing fingers weave the sweet-strung spell Between its chords; and as the wild notes swell, The sea-bird for those branches leaves the sea. But to what sound her listening ear stoops she? What netherworld gulf-whispers doth she hear, In answering echoes from what planisphere, Along the wind, along the estuary? She sinks into her spell: and when full soon Her lips move and she soars into her song, What creatures of the midmost main shall throng In furrowed self-clouds to the summoning rune, Till he, the fated mariner, hears her cry, And up her rock, bare breasted, comes to die?
