Where there is nothing, there is God. - William Butler Yeats

"Children play at being great and wonderful people, at the ambitions they will put away for one reason or another before they grow into ordinary men and women. Mankind as a whole had a like dream once; everybody and nobody built up the dream bit by bit, and the ancient story-tellers are there to make us remember what mankind would have been like, had not fear and the failing will and the laws of nature tripped up its heels. The Fianna and their like are themselves so full of power, and they are set in a world so fluctuating and dream-like, that nothing can hold them from being all that the heart desires."
from a preface to
Gods and Fighting Men
by Lady Augusta Gregory

I thought of your beauty, and this arrow,
Made out of a wild thought, is in my marrow.
There's no man may look upon her, no man,
As when newly grown to be a woman,
Tall and noble but with face and bosom
Delicate in colour as apple blossom.
This beauty's kinder, yet for a reason
I could weep that the old is out of season.

The creations of a great writer are little more than the moods and passions of his own heart, given surnames and Christian names, and sent to walk the earth.
