The British Library has compiled a treasury of medieval images of dragons in honor of Saint George’s Day.

Dragons are near-ubiquitious in medieval manuscripts.  They take pride of place in bestiaries and herbals, books of history and legend, and Apocalypse texts, to name a few.  They serve as symbols, heraldic devices, and even as ‘just’ decoration, and their physical characteristics can vary widely. Cinematic and literary depictions of dragons today are fairly consistent; they are almost always shown as reptilian, winged, fire-breathing creatures (in a word, Smaug).  But this was by no means a constant portrayal in the medieval period.

Let’s have a look at a very common medieval trope – of the dragon as the nemesis of a saint or angel.  Below we can see dragons facing off against St George (again), St Margaret, and the Archangel Michael.  All these examples are drawn from late 15th century manuscripts, but their dragons are very different, and range from a lizard-y animal with duck-like feet to a winged leonine creature and a demon.
