Victor Marie Hugo - A Storm Simile

See, where on high the moving masses, piled
By the wind, break in groups grotesque and wild,
Present strange shapes to view;
Oft flares a pallid flash from out their shrouds,
As though some air-born giant 'mid the clouds
Sudden his falchion drew.

Victor Marie Hugo
