(1)The sky was like a waterdrop
In shadow of a thorn,
Clear, tranquil, beautiful,
Dark, forlorn.
(5)Lightning along its margin ran;
A rumour of the sea
Rose in profundity and sank
Into infinity.
Lofty and few the elms, the stars
(10)In the vast boughs most bright;
I stood a dreamer in a dream
In the unstirring night.
