Memorable Couples in Literature

I have already listed here (on 7/7/11) some memorable weddings in literature ; today I broaden the list to some “memorable couples in literature.” In some cases the couples are memorable because of their great (if sometimes doomed) romances; in other cases they are remembered for being spectacularly unsuited to each other.

Lancelot and Guinevere
Heloise and Abelard
Romeo and Juliet
Othello and Desdemona
Anthony and Cleopatra
Elizabeth and Darcy (Pride and Prejudice)
Mr. and Mrs. Bennett (Pride and Prejudice)
Emma and Knightley (Emma)
Dorothea and Casaubon (Middlemarch)
Lydgate and Rosamond (Middlemarch)
Cathy and Heathcliff (Wuthering Heights)
Lady Chatterley and Mellors (Lady Chatterley’s Lover)
Rose of Sharon and Connie (Grapes of Wrath)
Celia and Shug (The Color Purple)

And here are some real life memorable literary couples:

Robert Browning and Elizabeth Barrett
James Joyce and Nora
F. Scott Fitzgerald and Zelda
