On the Vanity of Earthly Greatness (Arthur Guiterman, 1871-1943)

The tusks that clashed in mighty brawls
Of mastodons, are billiard balls.

The sword of Charlemagne the Just
Is ferric oxide, known as rust.

The grizzly bear whose potent hug
Was feared by all, is now a rug.

Great Caesar’s bust is on my shelf,
And I don’t feel so well myself.
