Dunsany on His Early Stories

In 1917, the John W. Luce Company of Boston published a "Gift Edition," a boxed edition of six volumes of his early stories. One set he inscribed (probably during his 1919 US tour), and it was put up for auction by Swann Galleries in 2011. Their catalog entry here shows the handwritten poem by Dunsany that he inscribed in The Gods of Pegana. I transcribe it here.

In a dream I must have gone,

  In a dream and sleeping fast, 

To a city never known,

  In a land that cannot last.

Thence these stories I have brought

  For your cities mad with steam,

That a dream from skies unthought

  May be mingled with your dream. 

Dunsany
