Poetry Month Is Icumen In

Some of the most famous lines in the English language, by Geoffrey Chaucer:

Whan that Aprille with his shoures soote
The droghte of Marche hath perced to the roote,
And bathed every veyne in swich licour,
Of which vertu engendred is the flour;
Whan Zephirus eek with his swete breeth
Inspired hath in every holt and heeth
The tendre croppes, and the yonge sonne
Hath in the Ram his halfe cours y-ronne, 
And smale fowles maken melodye,
That slepen al the night with open ye,
(So priketh hem nature in hir corages),
Than longen folk to goon on pilgrimages,
And palmers for to seken straunge strondes,
To ferne halwes, couthe in sondry londes;
And specially, from every shires ende
Of Engelond, to Caunterbury they wende,
The holy blisful martir for to seke,
That hem hath holpen, whan that they were seke.

And these, perhaps even more so, by T.S. Eliot:

April is the cruellest month, breeding
Lilacs out of the dead land, mixing
Memory and desire, stirring
Dull roots with spring rain.
Winter kept us warm, covering
Earth in forgetful snow, feeding
A little life with dried tubers.
