John Keats - 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.
