Bats have a long history of inclusion in the arts. The Ancient Greek playwright Aristophanes is believed to have been the first to allude to bats coming from hell in 414 BC, leading to the popular expression "bat out of hell". The Greek storyteller Aesop used bats as characters in two of his Fables,[1] and bats appear twice in the Ancient Greek epic poem the Odyssey.[4] One of the most famous bat-inspired characters is Batman, a superhero who debuted via American comic book in 1939.[19] In more recent times, bats are main characters in the children's book Stellaluna (1993) and the Silverwing series (1997 – 2007).[20]
