Norton Fitzwarren Dragon
Here the Roman general Ostorius was said to have killed hundreds of ancient Britons. Over the centuries a dragon is said to have grown from the corruption of the rotting bodies (this spontaneous growth of creatures from rotting matter was a common belief in Medieval times). The dragon took up residence in an Iron Age hill fort and preyed on the populace until Fulk Fitzwarine, a 13th century knight, slew the creature. Despite his brave deed Fulk fell foul of King John and was exiled. He continued his adventures abroad when he saved the Duke of Iberia’s daughter from a dragon near Carthage.
