Excerpt:

–Let us look each other in the face. We are Hyperboreans–we know well enough how remote our place is. “Neither by land nor by water will you find the road to the Hyperboreans”: even Pindar,in his day, knew that much about us.

We thirsted for the lightnings and great deeds; we kept as far as possible from the happiness of the weakling, from “resignation” . . .
