My spirit is too weak—mortality
  Weighs heavily on me like unwilling sleep,
  And each imagined pinnacle and steep
Of godlike hardship tells me I must die
Like a sick eagle looking at the sky.
  Yet 'tis a gentle luxury to weep
  That I have not the cloudy winds to keep
Fresh for the opening of the morning's eye.
Such dim-conceived glories of the brain
  Bring round the heart an undescribable feud;
So do these wonders a most dizzy pain,
  That mingles Grecian grandeur with the rude
Wasting of old time—with a billowy main—
  A sun—a shadow of a magnitude.
