The widespread appearance of the pears is well documented by a vast array of people of the times, including William Makepeace Thackeray, Heinrich Heine, Charles Baudelaire, Stendhal, and Sebastien Peyte, who wrote a book titled "Physiology of the Pear", collecting puns and spin-offs of the imagery. Victor Hugo in "Les Miserables" pays homage to the imagery as a young boy sketches an image of a pear on a wall, when the king helped him finish it and handed him a gold Louis coin saying, "The pear is on that too."
