Heard melodies are sweet, but those unheard
    Are sweeter: therefore, ye soft pipes, play on;
Not to the sensual ear, but, more endear'd,
    Pipe to the spirit ditties of no tone:
Fair youth, beneath the trees, thou canst not leave
    Thy song, nor ever can those trees be bare;
        Bold lover, never, never canst thou kiss,
Though winning near the goal - yet, do not grieve;
        She cannot fade, though thou hast not thy bliss,
    For ever wilt thou love, and she be fair!

Ah, happy, happy boughs! that cannot shed
    Your leaves, nor ever bid the spring adieu;
And, happy melodist, unwearied,
    For ever piping songs for ever new;
More happy love! more happy, happy love!
    For ever warm and still to be enjoy'd,
        For ever panting, and for ever young;
All breathing human passion far above,
    That leaves a heart high-sorrowful and cloy'd,
        A burning forehead, and a parching tongue.

Who are these coming to the sacrifice?
    To what green altar, O mysterious priest,
Lead'st thou that heifer lowing at the skies,
    And all her silken flanks with garlands drest?
What little town by river or sea shore,
    Or mountain-built with peaceful citadel,
        Is emptied of this folk, this pious morn?
And, little town, thy streets for evermore
    Will silent be; and not a soul to tell
        Why thou art desolate, can e'er return.

O Attic shape!  Fair attitude! with brede
    Of marble men and maidens overwrought,
With forest branches and the trodden weed;
    Thou, silent form, dost tease us out of thought
As doth eternity: Cold Pastoral!
    When old age shall this generation waste,
        Thou shalt remain, in midst of other woe
    Than ours, a friend to man, to whom thou say'st,
"Beauty is truth, truth beauty," - that is all
        Ye know on earth, and all ye need to know.
