and it's a whole bizarre genre:
Recently a group of us went into our manuscripts store to have a look at some medieval genealogical rolls. We were examining Royal MS 14 B V, an English roll from the last part of the 13th century which contains quite a lot of marginalia, when one of our post-medieval colleagues noticed a painting of a knight engaging in combat with a snail.
This struck him as odd, which struck the medievalists in the group as odd; surely everyone has seen this sort of thing before, right? As anyone who is familiar with 13th and 14th century illuminated manuscripts can attest, images of armed knights fighting snails are common, especially in marginalia. But the ubiquity of these depictions doesnt make them any less strange, and we had a long discussion about what such pictures might mean.
There has been much scholarly debate about the significance of these depictions of snail combat. As early as 1850, the magnificently-named bibliophile the Comte de Bastard theorised that a particular marginal image of a snail was intended to represent the Resurrection, since he discovered it in two manuscripts close to miniatures of the Raising of Lazarus. In her famous survey of the subject, Lilian Randall proposed that the snail was a symbol of the Lombards, a group vilified in the early middle ages for treasonous behaviour, the sin of usury, and non-chivalrous comportment in general. This interpretation accounts for why the snail is so frequently seen antagonising a knight in armour, but does not explain why the knight is often depicted on the losing end of this battle, or why this particular image became so popular in the margins of non-historical texts such as Psalters or Books of Hours.
