This article analyzes the text of Aristotle's Poetics in Parisinus Graecus 2038. There have been recent attempts to consider that this Ms, written around 1470 by Andronicos Callistos, contains primary readings. One must distinguish readings which are based on the scribe's analysis of the context, many of which coincide with those of the Arabic translation, from other cases where Andronicos tried to improve on readings of the paradosis. In the latter case, his attempts are nothing but either inferior readings or lectiones facitiores. This paper is especially concerned with Richard Janko's review of Taran-Gutas' 2012 edition of the Poetics (Brill). Centanni, Janko, and McOsker are now the main proponents of the reevaluation of Parisinus 2038 and the text of the Aldine edition of 1508. The author considers that such an approach is detrimental to the study of this difficult work.
