What is longest word ever to appear in all of literature?

"The Greek name of a type of fricassee
is thought to be the longest word ever to apear in all of literature:
coined by the ancient playwright Aristophanes, the word is

Lopadotemachoselachogaleokranioleipsanodrimhypotrimmatosilphioparaomelitokatakechymenokichlepikossyphophattoperisteralektryonoptekephalliokigklopeleiolagoiosiraiobaphetraganopterygon

Suffice it to say it's a fricassee that contains lots of ingredients."
