Don Juan 05-002
Canto the Fifth

I therefore do denounce all amorous writing,
     Except in such a way as not to attract;
Plain -- simple -- short, and by no means inviting,
     But with a moral to each error tack'd,
Form'd rather for instructing than delighting,
     And with all passions in their turn attack'd;
Now, if my Pegasus should not be shod ill,
This poem will become a moral model.

George Gordon Byron, Lord Byron (1788-1824)
