When I have fears that I may cease to be 
  Before my pen has glean’d my teeming brain, 
Before high piled books, in charact’ry, 
  Hold like rich garners the full-ripen’d grain; 
When I behold, upon the night’s starr’d face, 
  Huge cloudy symbols of a high romance, 
And think that I may never live to trace 
  Their shadows, with the magic hand of chance; 
And when I feel, fair creature of an hour! 
  That I shall never look upon thee more, 
Never have relish in the faery power 
  Of unreflecting love!—then on the shore 
Of the wide world I stand alone, and think 
Till Love and Fame to nothingness do sink.

Thou still unravish’d bride of quietness,
    Thou foster-child of Silence and slow Time,
Sylvan historian, who canst thus express
    A flowery tale more sweetly than our rhyme:
What leaf-fring’d legend haunts about thy shape
    Of deities or mortals, or of both,
        In Tempe or the dales of Arcady?
What men or gods are these? What maidens loth?
    What mad pursuit? What struggle to escape?
        What pipes and timbrels? What wild ecstasy?
 
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.

1.

My heart aches, and a drowsy numbness pains
  My sense, as though of hemlock I had drunk,
Or emptied some dull opiate to the drains
  One minute past, and Lethe-wards had sunk:
'Tis not through envy of thy happy lot,
  But being too happy in thine happiness,—
    That thou, light-winged Dryad of the trees,
          In some melodious plot
  Of beechen green, and shadows numberless,
    Singest of summer in full-throated ease.

2.

O, for a draught of vintage! that hath been
  Cool'd a long age in the deep-delved earth,
Tasting of Flora and the country green,
  Dance, and Provencal song, and sunburnt mirth!
O for a beaker full of the warm South,
  Full of the true, the blushful Hippocrene,
    With beaded bubbles winking at the brim,
          And purple-stained mouth;
  That I might drink, and leave the world unseen,
    And with thee fade away into the forest dim:

3.

Fade far away, dissolve, and quite forget
  What thou among the leaves hast never known,
The weariness, the fever, and the fret
  Here, where men sit and hear each other groan;
Where palsy shakes a few, sad, last gray hairs,
  Where youth grows pale, and spectre-thin, and dies;
    Where but to think is to be full of sorrow
          And leaden-eyed despairs,
  Where Beauty cannot keep her lustrous eyes,
    Or new Love pine at them beyond to-morrow.

4.

Away! away! for I will fly to thee,
  Not charioted by Bacchus and his pards,
But on the viewless wings of Poesy,
  Though the dull brain perplexes and retards:
Already with thee! tender is the night,
  And haply the Queen-Moon is on her throne,
    Cluster'd around by all her starry Fays;
          But here there is no light,
  Save what from heaven is with the breezes blown
    Through verdurous glooms and winding mossy ways.

5.

I cannot see what flowers are at my feet,
  Nor what soft incense hangs upon the boughs,
But, in embalmed darkness, guess each sweet
  Wherewith the seasonable month endows
The grass, the thicket, and the fruit-tree wild;
  White hawthorn, and the pastoral eglantine;
    Fast fading violets cover'd up in leaves;
          And mid-May's eldest child,
  The coming musk-rose, full of dewy wine,
    The murmurous haunt of flies on summer eves.

6.

Darkling I listen; and, for many a time
  I have been half in love with easeful Death,
Call'd him soft names in many a mused rhyme,
  To take into the air my quiet breath;
Now more than ever seems it rich to die,
  To cease upon the midnight with no pain,
    While thou art pouring forth thy soul abroad
          In such an ecstasy!
  Still wouldst thou sing, and I have ears in vain—
    To thy high requiem become a sod.

7.

Thou wast not born for death, immortal Bird!
  No hungry generations tread thee down;
The voice I hear this passing night was heard
  In ancient days by emperor and clown:
Perhaps the self-same song that found a path
  Through the sad heart of Ruth, when, sick for home,
    She stood in tears amid the alien corn;
          The same that oft-times hath
  Charm'd magic casements, opening on the foam
    Of perilous seas, in faery lands forlorn.

8.

Forlorn! the very word is like a bell
  To toil me back from thee to my sole self!
Adieu! the fancy cannot cheat so well
  As she is fam'd to do, deceiving elf.
Adieu! adieu! thy plaintive anthem fades
  Past the near meadows, over the still stream,
    Up the hill-side; and now 'tis buried deep
          In the next valley-glades:
  Was it a vision, or a waking dream?
    Fled is that music:—Do I wake or sleep?

O Goddess! hear these tuneless numbers, wrung
         By sweet enforcement and remembrance dear,
And pardon that thy secrets should be sung
         Even into thine own soft-conched ear:
Surely I dreamt to-day, or did I see
         The winged Psyche with awaken’d eyes?
I wander'd in a forest thoughtlessly,
         And, on the sudden, fainting with surprise,
Saw two fair creatures, couched side by side
         In deepest grass, beneath the whisp’ring roof
         Of leaves and trembled blossoms, where there ran
                A brooklet, scarce espied:

Mid hush'd, cool-rooted flowers, fragrant-eyed,
         Blue, silver-white, and budded Tyrian,
They lay calm-breathing, on the bedded grass;
         Their arms embraced, and their pinions too;
         Their lips touch’d not, but had not bade adieu,
As if disjoined by soft-handed slumber,
And ready still past kisses to outnumber
         At tender eye-dawn of aurorean love:
                The winged boy I knew;
But who wast thou, O happy, happy dove?
                His Psyche true!

O latest born and loveliest vision far
         Of all Olympus’ faded hierarchy!
Fairer than Phoebe's sapphire-region’d star,
         Or Vesper, amorous glow-worm of the sky;
Fairer than these, though temple thou hast none,
                Nor altar heap’d with flowers;
Nor virgin-choir to make delicious moan
                Upon the midnight hours;
No voice, no lute, no pipe, no incense sweet
         From chain-swung censer teeming;
No shrine, no grove, no oracle, no heat
         Of pale-mouth’d prophet dreaming.

O brightest! though too late for antique vows,
         Too, too late for the fond believing lyre,
When holy were the haunted forest boughs,
         Holy the air, the water, and the fire;
Yet even in these days so far retir'd
         From happy pieties, thy lucent fans,
         Fluttering among the faint Olympians,
I see, and sing, by my own eyes inspir’d.
So let me be thy choir, and make a moan
                Upon the midnight hours;
Thy voice, thy lute, thy pipe, thy incense sweet
         From swinged censer teeming;
Thy shrine, thy grove, thy oracle, thy heat
         Of pale-mouth’d prophet dreaming.

Yes, I will be thy priest, and build a fane
         In some untrodden region of my mind,
Where branched thoughts, new grown with pleasant pain,
         Instead of pines shall murmur in the wind:
Far, far around shall those dark-cluster’d trees
         Fledge the wild-ridged mountains steep by steep;
And there by zephyrs, streams, and birds, and bees,
         The moss-lain Dryads shall be lull’d to sleep;
And in the midst of this wide quietness
A rosy sanctuary will I dress
With the wreath’d trellis of a working brain,
         With buds, and bells, and stars without a name,
With all the gardener Fancy e’er could feign,
         Who breeding flowers, will never breed the same:
And there shall be for thee all soft delight
         That shadowy thought can win,
A bright torch, and a casement ope at night,
         To let the warm Love in!
