Worm of Linton
The Linton Worm is a mythical beast referred to in a Scottish borders legend dating back to the 12th century. "Wyrm" is the Old English for serpent. A 12th-century writer believed it to be "In length three Scots yards and bigger than an ordinary man’s leg – in form and callour to our common muir edders." The myth is similar to that of the more famous Lambton Worm.
Legend
The monster lived in a hollow on the northeast side of Linton Hill, a spot still known as the "Worm’s Den", at Linton in Roxburghshire on the Scottish borders. Emerging from its lair at dusk and dawn to ravage the countryside, eating crops, livestock and people, it proved invulnerable to the weapons ranged against it. The surrounding area became ruined by the beast's predations.
The news reached the ears of one (William or John) de Somerville, the Laird of Lariston and a man of reckless courage, who was in the south at that time. He travelled to the nearby village of Jedburgh and heard the lurid tales of the locals. Observing the beast himself he saw that the creature would open its mouth wide to swallow anything in its path but when faced with something too large to eat would remain still, with its mouth open. Sensing an opportunity he went to a local blacksmith and had him forge an iron covered spear with wheel at its tip which could impale a hunk of peat tipped in tar and brimstone. He practised riding with the burning spear to accustom his horse to the smoke.
