Thyself the lark melodious in mid-heaven;
Thyself the Protean shape of chainless cloud,
Pregnant with elemental fire, and driven
Through deeps of quivering light, and darkness loud
With tempest, yet beneficent as prayer;
Thyself the wild west wind, relentless strewing
The withered leaves of custom on the air,
And through the wreck pursuing
O’er lovelier Arnos, more imperial Romes,
Thy radiant visions to their viewless homes.
