Indeed, farts were treated so creatively in the Middle Ages that the topic is worth writing about. I'm no expert, so I began to look, and lo! I found the title that said it all: On Farting: Bodily Wind in the Middle Ages, by Valerie Allen and John Thompson, listed for September 2005 release by Palgrave.
Here's the publisher's synopsis:
The study of the fart in medieval culture participates in the widespread and productive contemporary study of the body, its practices and its hermeneutics. As a consequence of the cultural materialist interest in the quotidian, recent criticism has moved away from an abstracted conception of selfhood toward an appreciation of how the concrete daily regimens of bodily "habitus, generally taken for granted, shape the horizon of our cultural and individual consciousness. The fart, in its parodying of language and its logic of affinity, leads us ultimately to the problem of hermeneutics, of the art of interpretation itself. Although much of the medieval preoccupation with flatulence originates from the aesthetic of comic inversion, whereby farts "sing" or parody human language or are mistaken for departed souls, it also reflects a more serious interest in bodily health. A multifarious typology of the fart will permit a better understanding of the phenomenon's protean wealth of meaning.
Now this is one book that deserves a public reading.
The synopsis reminded me of a recent letter in Nature titled "Pressure also leads to worthless publications" in which Lindomar B. de Carvalho from the International Center for Condensed Matter Physics asked, "Are you wasting your time any more reading something fraudulent than reading something worthless?"
