I have seen old ships sail like swans asleep
Beyond the village which men still call Tyre,
With leaden age o'ercargoed, dipping deep
For Famagusta and the hidden sun
That rings black Cyprus with a lake of fire;
-copied from here.
"...the balloons...swelled high enough to catch the light of the hidden sun and shimmer with it."
-Poul Anderson, Tales Of The Flying Mountains (New York, 1984), p. 48.
We compare Anderson's Tales not only with other future histories but also with a poem by James Elroy Flecker.
