A Sunset Fancy

Wide in the west, a lake
Of flame that seems to shake
As if the Midgard snake
Deep down did breathe:
An isle of purple glow,
Where rosy rivers flow
Down peaks of cloudy snow
With fire beneath.

And there the Tower-of-Night,
With windows all a-light,
Frowns on a burning height;
Wherein she sleeps,
Young through the years of doom,
Veiled with her hair's gold gloom,
The pale Valkyrie whom
Enchantment keeps.
