Classic Poem

'Twas not a mist, nor was it quite a cloud,
But it pass'd smoothly on towards the Sea
Smoothly & lightly betwixt Earth & Heaven.
So thin a cloud--
It scarce bedimm'd the Star that shone behind it.
And Hesper now
Paus'd on the welkin's blue and cloudless brink,
A golden circlet! while the Star of Jove,
That other lovely star, high o'er my head
Shone whitely in the centre of his Haze
. . . one black-blue Cloud
Stretch'd, like the heavens o'er all the cope of Heaven.
