Edward Lear was an English artist, illustrator, author, and poet, renowned today primarily for his literary nonsense, in poetry and prose, and especially his limericks, a form that he popularised. Lear's nonsense books were quite popular during his lifetime, but a rumour circulated that "Edward Lear" was merely a pseudonym, and the books' true author was the man to whom Lear had dedicated the works, his patron the Earl of Derby. In Lear's limericks the first and last lines usually end with the same word rather than rhyming. For the most part they are truly nonsensical and devoid of any punch line or point. They are completely free of the off-colour humour with which the verse form is now associated.
