"These volumes, in addition to providing us with fine critical editions of the various Latin versions of the medieval Aristotelian corpus, contain a wealth of information about many aspects of medieval intellectual history." (R. Forrai, in: Bryn Mawr Classical Review, 2011.02.11)
The only medieval version of the Poetics stems from William of Moerbeke. However, it seems to have been unknown throughout the whole Middle Ages. Instead, Aristotle's work was known through Herman the German's version of Averroes' paraphrase. The text of this Arabic-Latin Poetria is also included in the volume.
