As a history buff - especially Egyptian history - I've always loved this poem. In fact, I loved it so much that I told my wife (when we were pregnant) that I would name the baby Ozymandias should it be a boy.
Lucky for her it was a girl :)

The poem:
I met a traveller from an antique land
Who said: “Two vast and trunkless legs of stone
Stand in the desert . . . 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!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.”
I love it so much because it can be interpreted on so many levels. I wish I knew who wrote it but sadly believe the author is still unknown.
