I’ve rather neglected the blog this year, particularly in the second half as the pressure of finishing up the PhD has intensified. Very nearly there though. So … I’m going to cheat a little for this post, and offer an adaptation of my thesis introduction that ponders generally why birds are so significant in medieval thinking and writing. Probably for much the same reasons as they are in any age or culture, but (without digressing into broader philosophical contemplation on birds), here are my thoughts.
For starters, medieval writers must have been struck by birds’ bipedalism. Their two-footedness would have resonated with a commonplace medieval image: bipedal heaven-facing man and quadrupedal earth-facing beast, often invoked to defend human, rational superiority. Birds, in this way, set themselves apart from mankind’s anatomically closest quadruped relatives. Like humans, they achieve an elevated status separating them from other nonhuman creatures, and consequently, this aligns them with certain human privileges. Medieval encyclopaedic discussion of birds certainly recognised the literal manner in which birds were elevated: they are ‘of the eire’, the ‘foules of hevene’ who physically occupy a space that even mankind is denied in his or her earthly time. Birds, of course, were classed as animals, but their unique aerial skills also divided them from the lowly beasts, earned them ‘special mencioun … in the texte of the bible’. Their strange mobility must surely have registered with the conventional hierarchy in which humans are poised midway between animals and angels, as recalled in artistic representations in which angels are typically depicted with birds’ wings.
Birds were outliers in medieval conceptions: on the one hand, base and subject to human dominion as any other creature; on the other, aligned with human abilities and privileges. Birds’ uniqueness confounds intellectual attempts to categorise at all, making them both the most rewarding and challenging creatures against and with which to contemplate species and identities, whether human, nonhuman or human-nonhuman. Birds not only defy categories, but in doing so, they display remarkable transformative abilities that at once distinguish them, and provide them with the means of persistent escape from these laboursome human efforts to classify. In Trevisa’s translation of Bartholomaeus’s popular De proprietatibus rerum (the standard medieval encyclopaedia), birds are described as ‘bytwene þe tweye elementis þat beþ most heuy and most liȝt’ [between the two elements that are most heavy and light]. Trevisa concludes: ‘it nediþ onliche to knowe þat among oþir kynde of beestis generalliche foules ben more pure and liȝt and noble of substaqunce and swift of meuynge and scharp of siȝt’ [it is only necessary to know that among other kinds of beasts generally, birds are more pure and light and noble of substance, swift of moving, and sharp of sight’.
Perhaps even more alluring, though, is the medieval belief that birds’ flight engages these creatures in transformative evasions that literally leave no traces by which we might purchase more tangible understandings of avian being. Bartholomaeus states that birds are ‘without waye’ … for here [their] wayes in the eyre be not distinguyd in certayne’. Like other encyclopaedic treatments of the natural world, Bartholomaeus borrows from the hugely influential authority of Isidore of Seville (6th-7th cen.), whose observations on birds proliferate right across the Middle Ages: ‘They are called birds (avis) because they do not have set paths (via), but travel by means of pathless (avia) ways’. For Isidore, the very name for these creatures in Latin reveals their defining characteristic; not simply flight, but secretive flight known only to birds themselves.
There is another aspect of bird kind that Isidore identifies and which is repeated by his imitators. He notes that ‘There is a single word for birds, but various kinds, for just as they differ among themselves in appearance, so do they differ also in the diversity of their natures’. The great diversity of birds, as much as their flight, perpetuates the avian enigma. It is quite impossible (because ‘anone aftir þe fliȝt þe eire closiþ itself and leueþ noo signe neiþir tokene of here passage’ [immediately after their flight the air closes itself and leaves no sign nor trace of their passage]) for mankind ‘to penetrate all the wildernesses of India and Ethiopia and Scythia, so as to know the kinds of birds and their differentiating characteristics’.
In all their diversity, birds embody, perform and represent transformation, variously and wondrously in their colours, moults, migrations, flights, oviparous reproduction, songs and displays. Medieval writers marvelled at how their prolific diversity of kind and appearance, and their distant, untraceable directions, make these aerial shape-shifters masters of evasion, misdirection and resistance, always moving across and beyond.
