A casement high and triple-arched there was, All garlanded with carven imag'ries Of fruits, and flowers, and bunches of knot-grass, And diamonded with panes of quaint device, Innumerable of stains and splendid dyes, As are the tiger-moth's deep-damasked wings.

-Keats,John
  Lamia, Isabella, The Eve of St.  Agnes and Other Poems,'The Eve of St.  Agnes', stanza 24.

Full on this casement shone the wintry moon, And threw warm gules on Madeleine's fair breast, As down she knelt for heaven's grace and boon; Rose-bloom fell on her hands, together prest, And on her silver cross soft amethyst, And on her hair a glory like a saint: She seemed a splendid angel, newly drest, Save wings, for heaven.

-Keats,John
  Lamia, Isabella, The Eve of St.  Agnes and Other Poems,'The Eve of St.  Agnes', stanza 25.

And if no Lethe flows beneath your casement, And when ten years have not brought full effacement, Philosophy was wrong, and you may meet.

-Ransom,John Crowe
  Grace after Meat,'Parting at Dawn'.

   Ah, sad and strange as in dark summer dawns The earliest pipe of half-awakened birds To dying ears, when unto dying eyes The casement slowly grows a glimmering square; So sad, so strange, the days that are no more. Dear as remembered kisses after death, And sweet as those by hopeless fancy feigned On lips that are for others; deep as love, Deep as first love, and wild with all regret; O Death in Life, the days that are no more.

-Tennyson
  The Princess, pt.4, added song, stanzas 3^4.

All night has the casement jessamine stirred To the dancers dancing in tune; Till a silence fell with the waking bird, And a hush with the setting moon.

-Tennyson
  Maud, pt.1, sect.22, stanza 3, l.864^7.

John Bull has gone to India And all must pay him heed For histories are there to prove That none of another breed Has had a like inheritance, Or sucked such milk as he, And there's no luck about a house If it lacks honesty. The ghost of Roger Casement Is beating on the door.

-Yeats,W(illiam) B(utler)
