A Coat

I made my song a coat
Covered with embroideries
Out of old mythologies
From heel to throat;
But the fools caught it,
Wore it in the world's eyes
As though they wrought it.
Song, let them take it,
For there's more enterprise
In walking naked.

William Butler Yeats

The Angel

I dreamt a dream! What can it mean?
And that I was a maiden Queen
Guarded by an Angel mild:
Witless woe was ne'er beguiled!

And I wept both night and day,
And he wiped my tears away;
And I wept both day and night,
And hid from him my heart's delight.

So he took his wings, and fled;
Then the morn blushed rosy red.
I dried my tears, and armed my fears
With ten thousand shields and spears.

Soon my Angel came again;
I was armed, he came in vain;
For the time of youth was fled,
And grey hairs were on my head.

--William Blake, Songs of Experience
