On Seeing the Elgin Marbles

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 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

John Keats
