The planet orb of fire, whereon he rode
Each day from east to west the heavens through, 270
Spun round in sable curtaining of clouds;
Not therefore veiled quite, blindfold, and hid,
But ever and anon the glancing spheres,
Circles, and arcs, and broad-belting colure,
Glow'd through, and wrought upon the muffling dark
Sweet-shaped lightnings from the nadir deep
Up to the zenith,--hieroglyphics old,
Which sages and keen-eyed astrologers
Then living on the earth, with labouring thought
Won from the gaze of many centuries: 280
Now lost, save what we find on           huge
Of stone, or marble swart; their import gone,
Their wisdom long since fled.
