William Butler Yeats - Under The Moon

I HAVE no happiness in dreaming of Brycelinde,
Nor Avalon the grass-green hollow, nor Joyous Isle,
Where one found Lancelot crazed and hid him for a while;
Nor Uladh, when Naoise had thrown a sail upon the wind;
Nor lands that seem too dim to be burdens on the heart:
Land-under-Wave, where out of the moon's light and the sun's
Seven old sisters wind the threads of the long-lived ones,
Land-of-the-Tower, where Aengus has thrown the gates apart,
And Wood-of-Wonders, where one kills an ox at dawn,
To find it when night falls laid on a golden bier.
Therein are many queens like Branwen and Guinevere;
And Niamh and Laban and Fand, who could change to an otter or fawn,
And the wood-woman, whose lover was changed to a blue-eyed hawk;
And whether I go in my dreams by woodland, or dun, or shore,
Or on the unpeopled waves with kings to pull at the oar,
I hear the harp-string praise them, or hear their mournful talk.
Because of something told under the famished horn
Of the hunter's moon, that hung between the night and the day,
To dream of women whose beauty was folded in dis may,
Even in an old story, is a burden not to be borne.

William Butler Yeats
