|Other name(s)||White worm or whiteworm|
Lindworms were popular motifs on runestones in 11th century Sweden. Portrayals vary across countries and the stories in which they appear, the creature generally appearing as wingless with a serpentine body, dragon's head, scaled skin and two clawed forelimbs. Depictions imply lindworms do not walk on their two limbs like a wyvern, but move like a mole lizard: they slither like a snake and use their arms for traction.
The head of the 16th century lindworm statue at Lindwurm Fountain in Klagenfurt is modeled on the skull of a woolly rhinoceros found in a nearby quarry in 1335. It has been cited as the earliest reconstruction of an extinct animal. 
According to Charles Boutell a lindworm is "a dragon without wings".
Lindworm derives from Old High German lint and orm, perhaps from the Proto-Germanic adjective *linþia- meaning "flexible", or perhaps by way of Old Danish/Old Saxon lithi, Old High German lindi, "soft, mild" (German lind, (ge)linde), Old English liðe (English lithe, "agile"). The term occurs in Middle High German as lintwurm and was adopted from German into Scandinavia as Old Swedish lindormber, Danish lindorm. In Icelandic, the term linnormr was used to translate German sources to produce Þiðreks saga (an Old Norse chivalric saga adapted from the Continent from the late 13th c.)
An Austrian tale from the 13th century tells of a lindworm that lived near Klagenfurt. Flooding threatened travelers along the river, and the presence of the lindworm was blamed. A duke offered a reward to anyone who could capture it and so some young men tied a bull to a chain, and when the lindworm swallowed the bull, it was hooked like a fish and killed.
The shed skin of a lindworm was believed to greatly increase a person's knowledge about nature and medicine.
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.
The sighting of a "whiteworm" once was thought to be an exceptional sign of good luck.
The knucker or the Tatzelwurm is a wingless biped, and often identified as a lindworm. In legends, lindworms are often very large and eat cattle and human corpses, sometimes invading churchyards and eating the dead from cemeteries.
In the 19th-century tale of "Prince Lindworm" (also "King Lindworm") from Scandinavian folklore, a "half-man half-snake" lindworm is born, as one of twins, to a queen, who, in an effort to overcome her childlessness, followed the advice of an old crone who instructed her to eat two onions. As she did not peel the first onion, the first twin was born a lindworm. The second twin is perfect in every way. When he grows up and sets off to find a bride, the lindworm insists that a bride be found for him before his younger brother can marry. Because none of the chosen maidens are pleased by him, he eats each until a shepherd's daughter who spoke to the same crone is brought to marry him, wearing every dress she owns. The lindworm tells her to take off her dress, but she insists he shed a skin for each dress she removes. Eventually his human form is revealed beneath the last skin. Some versions of the story omit the lindworm's twin, and the gender of the soothsayer varies. A similar tale occurs in the 1952 novel The Voyage of the Dawn Treader by C.S. Lewis.
The tale of Prince Lindworm is part of a multiverse of tales in which a maiden is betrothed or wooed by a prince enchanted to be a snake or other serpentine creature (ATU 433B, "The Prince as Serpent"; "King Lindworm").
Late belief in lindorm in Sweden
The belief in the reality of a lindorm, a giant limbless serpent, persisted well into the 19th century in some parts. The Swedish folklorist Gunnar Olof Hyltén-Cavallius (1818–1889) collected in the mid 19th century stories of legendary creatures in Sweden and met several people in Småland, Sweden who said they had encountered giant snakes, sometimes equipped with a long mane. He gathered around 50 eyewitness reports, and in 1884 offered a cash reward for a captured specimen, dead or alive. Hyltén-Cavallius came to be ridiculed by Swedish scholars and as no one ever managed to claim the reward it resulted in a cryptozoological defeat. Rumours of the existence of lindworms in Småland soon abated.
