A Man Young And Old: I. First Love by William Butler Yeats
Though nurtured like the sailing moon
In beauty's murderous brood,
She walked awhile and blushed awhile
And on my pathway stood
Until I thought her body bore
A heart of flesh and blood.
But since I laid a hand thereon
And found a heart of stone
I have attempted many things
And not a thing is done,
For every hand is lunatic
That travels on the moon.
She smiled and that transfigured me
And left me but a lout,
Maundering here, and maundering there,
Emptier of thought
Than the heavenly circuit of its stars
When the moon sails out.
