Well... here's one that's rather amusing, I think... But I can't think of a favorite one at the moment... so I'll just share this one and the next..
William Shakespeare wrote:Sonnet 130
My mistress' eyes are nothing like the sun;
Coral is far more red than her lips' red;
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses see I in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound;
I grant I never saw a goddess go;
My mistress, when she walks, treads on the ground:
And yet, by heaven, I think my love as rare
As any she belied with false compare.
Here's the other one that I just think is interesting... because there's a puzzle within it...
Edgar Allan Poe wrote:A Valentine
For her this rhyme is penned, whose luminous eyes,
Brightly expressive as the twins of Loeda,
Shally find her own sweet name, that, nestling lies
Upon the page, enwrapped from every reader.
Search narrowly the lines!-- they hold a treasure
Divine-- a talisman-- an amulet
That must be worn at heart. Search well the measure--
The words-- the syllables! Do not forget
The trivialest point, or you may lose your labor!
And yet there is in this no Gordian knot
Which one might not undo without a sabre,
If one could merely comprehend the plot.
Enwritten upon the leaf where now are peering
Eyes' scintillating soul, there lie perdus
Three eloquent words oft uttered in the hearing
Of poets, by poets-- as the name is a poet's too.
It's letters, although naturally lying
Like the knight Pinto-- Mendez Ferdinando--
Still form a synonym for Truth.-- Cease trying!
You will not read the riddle though you do the best that you can do.
To get the puzzle, you read the first letter of the first line in conjunction with the second letter of the second line, then the third letter of the third line, so on and so forth to the end... and you'll get the name of who it was written for.
