When the Princess Badoura was placed on Prince Camaralzamans bed, in order to compare their claims to beauty, the fairy Maimounë changed herself into a flea, and bit the prince on the neck in order to awake him. Next, the genius Danhasch changed himself into a flea and bit the princess on the lip, that she might open her eyes and see the prince. (Arabian Nights; Camaralzaman and Badoura.)
