The rock was black, the cloud was white:
The black rock in a gorge was set.
Earth rose, heaven stooped: upon that hight
The thunder with the torrent met.

The vast half-weeping cloud came down,
Storm-laden: and a demon form,
Of gathered wrath, stood with a frown
Upon that pedestal of storm.

He stood, his rolling mantle spread,
His hat of darkness deeply set:
His locks heaven cloudlike round his head;
The torrent lashed his feet of jet.

Forth from his eyes the lightning leapt,
His voice spake with the thunder's tone:
Earth's waters in swift flashes swept,
Her caverns answered with a groan.
