A serpentine monster with the head of a "salamander" features in the legend of the Lambton Worm, a serpent caught in the River Wear and dropped in a well, which 3–4 years thence, terrorized the countryside of Durham while the nobleman who caught it was at the Crusades. Upon return, he received spiked armour and instructions to kill the serpent, but thereafter to kill the next living thing he saw. His father arranged that after the lindworm was killed, a dog would be released for that purpose; but instead of releasing the dog the nobleman's father ran to his son, and so incurred a malediction by the son's refusal to commit patricide. Bram Stoker used this legend in his short story "Lair of the White Worm".
