On Seeing the Elgin Marbles lyrics

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-conceivéd glories of the brain
     Bring round the heart an indescribable 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.
