Various characters from this epic have themselves become cultural icons in Western culture, such as Aladdin, Sinbad and Ali Baba. Part of its popularity may have sprung from improved standards of historical and geographical knowledge. The marvelous beings and events typical of fairy tales seem less incredible if they are set further "long ago" or farther "far away"; this process culminates in the fantasy world having little connection, if any, to actual times and places. Several elements from Arabian mythology are now common in modern fantasy, such as genies, bahamuts, magic carpets, magic lamps, etc. When L. Frank Baum proposed writing a modern fairy tale that banished stereotypical elements, he included the genie as well as the dwarf and the fairy as stereotypes to go.
