The early Britons, from whom the modern Welsh are descended, provide us with our earliest surviving European accounts of reptilian monsters, one of whom killed and devoured king Morvidus (Morydd) in ca 336 BC. We are told in the account translated for us by Geoffrey of Monmouth, that the monster 'gulped down the body of Morvidus as a big fish swallows a little one.' Geoffrey described the animal as a Belua.3
