Page 202 - Thus with the year Seasons return, but not to me returns Day, or the sweet approach of even or morn, Or sight of vernal bloom, or summer's rose, Or flocks, or herds, or human face divine: But cloud instead, and ever-during dark Surrounds me, from the cheerful ways of men Cut off, and for the book of knowledge fair Presented with a universal blank Of nature's works, to me expunged and rased, And wisdom at one entrance quite shut out.

Page 17 - Revisiting the glimpses of the moon, Not like thin ghosts, or disembodied creatures, But with thy bones and flesh, and limbs and features. Tell us, for doubtless thou canst recollect, To whom should we assign the Sphinx's fame ? Was Cheops or Cephrenes architect Of either pyramid that bears his name ?

Revisiting the glimpses of the moon, Not like thin ghosts or disembodied creatures, But with thy bones and flesh, and limbs and features.
Page 202 - Though hard and rare : thee I revisit safe, And feel thy sovran vital lamp ; but thou Revisit'st not these eyes, that roll in vain To find thy piercing ray, and find no dawn ; So thick a drop serene hath quenched their orbs, Or dim suffusion veiled.
Page 16 - AND thou hast walked about (how strange a story!) In Thebes's streets three thousand years ago, When the Memnonium was in all its glory, And time had not begun to overthrow Those temples, palaces, and piles stupendous, Of which the very ruins are tremendous!
Page 114 - Fair all the pageant, — but how passing fair The slender form which lay on couch of Ind ! O'er her white bosom strayed her hazel hair, Pale her dear cheek, as if for love she pined ; All in her night-robe loose she lay reclined...
Page 18 - Thou couldst develop — if that withered tongue Might tell us what those sightless orbs have seen — How the world looked when it was fresh and young, And the great deluge still had left it green; Or was it then so old that history's pages Contained no record of its early ages ?
