Classic Poem

I saw a river swift, whose fomy billowes
Did wash the ground work of an old great wall;
I saw it cover'd all with griesly shadowes,
That with black horror did the ayre appall:
Thereout a strange beast with seven heads arose,
That townes and castles under her brest did coure,
And seem'd both milder beasts and fiercer foes
Alike with equall ravine to devoure.
Much was I mazde, to see this monsters kinde
In hundred formes to change his fearefull hew;
When as at length I saw the wrathfull winde,
Which blows cold storms, burst out of Scithian mew,
That sperst these cloudes, and in so short as thought,
This dreadfull shape was vanished to nought.
