Medieval knights battling snails

Snails are surprisingly common depictions in the marginalia of medieval manuscripts, often depicted in battle with armored knights.

Sometimes the creatures appear to be hovering, attacking knights in mid-air. Occasionally there is more than one. This is the uniquely medieval phenomenon of the fighting snail – and to this day, why they were depicted remains utterly mysterious...

But for a brief period in the late 13th Century, illuminators – those who decorated books – across Europe embraced a new obsession: fighting snails. For a comprehensive study of these warring gastropods, the art historian Lilian Randall counted 70 examples, in 29 different books – most of which were printed in the two decades between 1290 and 1310. The illustrations are found across Europe, but particularly in France, where there was a thriving manuscript-production industry at the time, says Clarke.

The specific scenarios that warring snails found themselves in varied, but broadly followed the same format of a snail-assailant standing off against a knight. Often, the molluscs have their antenna – technically their upper tentacles, or ommatophores – pointed aggressively forwards, as though they were swords. In one, a snail is shown fighting a nude woman. In a few they're not depicted as regular molluscs at all, but hybrids between snails and men – who are being ridden by rabbits, naturally.
