Clement Clarke Moore is the author credited with the famous poem The Night Before Christmas. Supposedly, he wrote it one Christmas for his children, but didn't publish it himself. One of his children gave it to a friend who sent it for publication in 1823. Moore published it in an anthology of his own poems in 1844. It was known then as A Visit From St Nicholas. Now it is the 'most-published, most-read, most-memorised and most-collected book in all of Christmas literature.'
So many well-known children's illustrators have done a version or a spin-off version (parody). It is easy to parody or innovate upon because it has such a distinctive rhythm.
