Commonplace Book

In honour of Neil Gaiman's very entertaining blog, most recently entitled The Return of The Devil's Foot, an oldie but a goodie:

Song
Go and catch a falling star,
Get with child a mandrake root,
Tell me where all past years are,
Or who cleft the devils foot;
Teach me to hear mermaids singing,
Or to keep off envy's stinging,
    And find
    What wind
Serves to advance an honest mind.

If thou be'st born to strange sights,
Things invisible to see,
Ride ten thousand days and nights
Till Age snow white hairs on thee;
Thou, when thou return'st wilt tell me
All strange wonders that befell thee,
    And swear
    No where
Lives a woman true and fair.

If thou find'st one let me know;
Such a pilgrimage were sweet.
Yet do not; I would not go,
Though at next door we might meet.
Though she were true when you met her,
And last, till you write your letter,
    Yet she
    Will be
False, ere I come, to two or three.
    -- John Donne

Used to good effect in Howl's Moving Castle by Dianna Wynne Jones, although it was, alas, left out of the recent movie.
