This is perhaps the most grotesque of the creatures in this series. It is an awkward-looking reptile, a dragon with only two legs and no wings, but “bipedal, wingless dragon” sounds more erudite. Alternatively, one might view it as a two-legged serpent. It is another of the creatures used in heraldry.
There are different ways to interpret a Lindworm. Sometimes they are shown as walking on two “hind” legs on which they balance. The forelimbs are obviously missing. This approach seems to me to be the one used in the following coat of arms.
My eyes were drawn to the following illustration for its bold lines and its detail and because it incorporates elements of an older style. As the credit at the lower right of the drawing implies, I believe it was drawn by an artist who goes by the name of Liza Phoenix. If I am wrong please correct me so that I can update my information.
Alternatively, a Lindworm may be portrayed as lacking hind legs and writhing like a snake. Its forelimbs might be used for pulling itself along and/or grabbing at prey as in the next illustration (for which I could find no credit).
Pictures like these used to rev my motor when I was a boy. Actually, they still do. Next week, I will mention a variant of the Lindworm.
