And what rough beast, its hour come round at last, Slouches toward Bethlehem to be born? - William Butler Yeats

My fiftieth year had come and gone,
I sat, a solitary man,
In a crowded London shop,
An open book and empty cup
On the marble table-top.

While on the shop and street I gazed
My body of a sudden blazed;
And twenty minutes more or less
It seemed, so great my happiness,
That I was blessed and could bless.

I heard the old, old, men say 'all that's beautiful drifts away, like the waters.

Speech after long silence; it is right,
All other lovers being estranged or dead,
Unfriendly lamplight hid under its shade,
The curtains drawn upon unfriendly night,
That we descant and yet again descant
Upon the supreme theme of Art and Song:
Bodily decrepitude is wisdom; young
We loved each other and were ignorant.
