“That ‘Poetry is the cradle of philosophy’ is axiomatic”(John of Salisbury, Metalogicon I.22).

It is a truth generally acknowledged that in the Middle Ages a liberal arts education consisted of the trivium (grammar, logic, and rhetoric) and the quadrivium (arithmetic, music, geometry, astronomy). Poetry –what we might call “literature”– was primarily taught by grammarians and rhetoricians in the Middle Ages. Literary scholars, like Rita Copeland and Marjorie Woods, have therefore been very motivated to study exactly what the language disciplines of Grammar and Rhetoric entailed and precisely how they were taught in order to have a better sense of what the study of literature must have looked like in this period. Their works are indispensable for the study of medieval literature and truly are the bulk of where instruction in poetics lay in the Middle Ages. And yet, once cannot stop there.

Knowing exactly where to put poetry was something that clearly bothered many medieval philosophers. While today we might assume that poetry would clearly be associated with the Trivium, or the arts dedicated to words, specifically grammar and rhetoric, certain medieval thinkers located it within logic and also the Quadrivium, or the arts of number. Understanding why can help us to understand the multi-faceted way in which the medieval mind approached poetry in particular and the literary arts more generally.

In the twelfth century when there were major curricular changes afoot in schools and universities, John of Salisbury maintained that poetry belonged to the art of grammar although it was closely allied with rhetoric. “Art,” writes John of Salisbury, “is a system that reason has devised in order to expedite, by its own short cut, our ability to do things within our natural capacities. Reason neither provides nor professes to provide the accomplishment of the impossible;” Instead, reason pursues the possible by means of an efficient plan, what the Greeks would call a methodon (Metalogicon I.11, p.33). As J.J. Murphy writes in the Cambridge History of Literary Criticism, Vol. II: The Middle Ages:

In medieval terminology the Latin word ars (plural: artes) denoted a body of principles relating to a specific activity such as painting, music, preaching, or writing. By extension the term was also used for a written treatise on the subject of a particular art […] The term ‘art’ or ars when applied to such a treatise indicates a discussion of what the ancient Greeks would have called techné ––‘technique’ or ‘craft’ –– rather than an abstract or theoretical discussion of a subject (p.42).

The practitioner of an art is therefore called an artifex or craftsman, and the study of the art consisted of both the intrinsic principles for practice and the extrinsic practice of the art itself.[1] When art is understood in this way, craftsmen generally agree that the person able to produce art is more skilled that the person skilled at conveying the principles underlying art. While poetry was clearly a craft that required a practitioner to study a method of practice, it was by no means clear where it ought to fit in the medieval curriculum of the arts.

John of Salisbury reports that some people thought poetry should be its own subject (shockingly!) because so much of it is clearly a “product of nature’s workshop” (Metalogicon I.18). The close tie between poetry and nature formed the basis of their argument, but John of Salisbury warns pragmatically that if poetry is removed from grammar, “its mother and the nurse of its study,” the study of poetry could be “dropped from the roll of liberal studies.” In other words, everyone studies grammar, which in those days often included a careful study of works like Virgil’s Aeneid. If poetry became its own subject, people might not take it at all!

Some philosophers thought that poetry actually belonged to the subject of logic. These people were especially concerned about how to classify Aristotle’s Poetics. In Ancient Greece, Aristotle had written a group of works (one might even say lecture notes) on logic when teaching at the Lyceum. His followers, the Peripatetics, classified these works as the Organon, meaning instrument or tool, because they saw them as instrumental in preparing for the study of philosophy. The Latin West had only select works from the Organon until their increased contact with Arabic philosophers like Avicenna, who wrote a commentary on the Poetics. Following the Greek commentators on Aristotle, most of the Arabic (and subsequently Latin scholastic) commentators saw Aristotle’s Rhetoric and Poetics as the seventh and eighth works of Aristotle’s Organon. In their zeal, therefore, to comment on the entirety of the Organon, some Latin scholastic commentators, like Herman the German, viewed poetics as a part of Logic.

As surprising as it might be to think that poetry should be considered primarily within the context of “logic,” there is strong evidence that poetry was also studied within the context of the quadrivium. And yet, many medieval thinkers, the Pythagorean believed that number lay at the root of creation itself. For example, Dante writes in the Convivio when commenting on the beauty of a canzone:

All of you who cannot perceive the meaning of this canzone, do not reject it on that account, but consider its beauty: considerable for the way it is constructed, which is the concern of the grammarians; the ordering of its discourse, which is the concern of the rhetoricians; and for the metrical numbering of its parts, which is the concern of poets. (II.xi.9–10)

The key word to focus upon here is numbering. Familiarity with the Commedia and its frequent references to the starsis enough to convince a reader that one aspect of the numbering that Dante had in mind was the medieval discipline of astronomy, but there is also good reason to think that Dante had music in mind. Some of this evidence is textual…the numerous references to music in the Purgatorio and Paradiso…, but some of this evidence can be found in Boethius.
