Even the most cursory glance over the pages of medieval manuscripts will reveal a plethora of insects.  Bugs are everywhere – although we hasten to add that we are extremely vigilant about avoiding the presence of any actual living insects within the pages of our books.  But there has been little comprehensive scholarship about the appearance of such creatures in medieval manuscripts.  Insects usually live literally in the margins, often not even appearing in catalogue entries despite their profusion.

Whilst undertaking this very short exploration of the subject, therefore, we would do well to remember the words of one of the earliest writers about these minute creatures.  As Pliny the Elder reminds us in the introduction to his book about insects:  ‘Nature is nowhere to be seen in greater perfection than in the very smallest of her works.  For this reason then, I must beg of my readers, notwithstanding the contempt they feel for many of these objects, not to feel a similar disdain for the information I am about to give relative thereto, seeing that, in the study of Nature, there are none of her works that are unworthy of our consideration.’

We’ll begin, as we almost always do, with the bestiary, that essential book of medieval beasts.  The early medieval bestiary includes amongst its pages only two species of what we would consider insects today – ants and bees.

The humble ant is given quite extensive treatment in the bestiary.  Echoing Isidore of Seville’s somewhat fanciful etymology, the text tells us that the ant is called ‘formica’ because it carries pieces of grain (‘ferat micas’).   It goes on to describe much recognisable ant behaviour, detailing how ants walk in lines to gather food, store it for the winter, carry loads far in excess of their own size, and work together for the good of the group.

A parallel tradition to that of the bestiary is the Physiologus, one of the precursors to the Marvels of the East.  In the Physiologus, a subspecies of ant, as large as dogs, is said to live in Ethiopia and to be adept at digging up gold.  Such skill can be exploited by human beings, but only very carefully, as these ants will try to chase down and kill anyone who attempts to steal from them.

The concept of insects as a distinct class of animals was one that didn’t exist in this period.  Bees, for example, are characterised as the ‘smallest of birds’, and accordingly, often come at the end of the bestiary's section on winged animals.  They are described as industrious creatures, living in community under a chosen king.  Born in the decaying bodies of oxen or slaughtered calves, it is said, bees build their homes with ‘indescribable skill’, make honey, and then guard it fiercely against all potential invaders.  Much like ants, bees were praised over the centuries by various authors who considered them humble and loyal animals, ‘wonderfully noble', and worthy of emulation by human beings.

That said, bees could sometimes be used as weapons.  A mid-13th century copy of William of Tyre’s Histoire d’Outremer contains a miniature of the Patriarch of Antioch who was bound to a tower and smeared with honey in a gruesome attempt to end his life.

It is not clear why the early bestiaries omitted so many of the species of insects that people must surely have been familiar with – in many cases, perhaps, far too familiar. Flies, spiders, moths, and butterflies do not put in appearances in texts until later.  The British Library is lucky enough, however, to possess a mid-16th century Greek copy of Manuel Philes’ De animalium proprietate which includes a cicada (f. 13r), a locust-like insect (f. 19r), and three species of spider – two of which are poisonous (and one of which is apparently six-legged).

Six-legged spiders are not unusual to find in medieval art, and neither are their ten-legged cousins, as the examples below will show:

Most insects in medieval art, however, were not designed to illustrate any accompanying text, or at least, not literally. This is particularly the case for manuscripts from the later medieval era.  The vast majority of insect examples we have found are decorative ones, taking their place amongst the flowers, fruit, and jewels that adorn these pages.  Some are occasionally used for humorous purposes, or may have been intended to underscore the message of the text.   An extremely small selection of these sorts of images is below; if we have omitted any gems, please do let us know in the comments or on Twitter: @BLMedieval.  Happy bug hunting!
