Résumé :
Represented by two separate Greek manuscripts, the Parisinus gr. 1741 (10th century) and the Riccardianus 46 (12th century), as well as by medieval Arabic and Latin translations, the direct tradition of Aristotle’s Poetics has come to us in an incomplete and often problematic form. Despite these difficulties – which are in part inherited from antiquity – a knowledge of the text, even if punctual and limited, can be detected in references made by Eustratius of Nicaea, as well as in a short treatise On Tragedy attributed to Psellos. Combined with the information we can glean from the analysis of the two Greek manuscripts, this evidence demonstrates the role played, at different times, by various Byzantine scholars, in the – at least partial – survival of Poetics.
