His foe was folly and his weapon wit... Oh, for an hour of...

A Crocodile

Har by the lilied Nile I saw
A dusking river-dragon stretched along,
The brown habergeon of his limbs enamel-led
With sanguine almandines and rainy pearl;
And on his back there lay a young one sleeping,
No bigger than a mouse; with eyes like beads,
And a small fragment of its speckled egg.
Remaining on its harmless, pulpy snout;
A thing to laugh at, as it gaped to catch
The baulking merry flies. In the iron jaws
Of the great devil-beast, like a pale soul
Fluttering in rocky hell, lightsomely flew
A snowy trochilus, with roseate beak
Tearing the hairy leeches from his throat.
