For anyone interested in poetry, there is always Shelley’s The Mask of the Anarchy.
LXXXVIII.
"And the bold, true warriors,
Who have hugged Danger in wars,
Will turn to those who would be free
Ashamed of such base company:LXXXIX.
"And that slaughter to the nation
Shall steam up like inspiration,
Eloquent, oracular,
A volcano heard afar:XC.
"And these words shall then become
Like Oppressions thundered doom,
Ringing through each heart and brain,
Heard again–again–again.XCI.
Rise like lions after slumber
In unvanquishable NUMBER!
Shake your chains to earth, like dew
Which in sleep had fall’n on you:
YE ARE MANY-THEY ARE FEW.
Ozymandias is a classic, too.
I MET a Traveler from an antique land,
Who said, "Two vast and trunkless legs of stone
Stand in the desart. Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read,
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed:
And on the pedestal these words appear:
“My name is OZYMANDIAS, King of Kings.”
Look on my works ye Mighty, and despair!
No thing beside remains. Round the decay
Of that Colossal Wreck, boundless and bare,
The lone and level sands stretch far away.
