Casio Longino, fr. 42.75 P.-B. ¿Un gramático llamado Odiseo o un error textual?: una propuesta de corrección

The 3th century grammarian Cassius Longinus in his introduction to the commentary to Hephaestion’s On Metre (Ἐγχeιρίδιον πeρὶ μέτρων) mentions a writer on meter named Odysseus (Ὀδυσσeὺς ὁ μeτρικός), who is not known in any other source. This paper aims to identify this author and give a satisfactory explanation to his mention by Longinus. However, the peculiarity of the name, which is not attested as anthroponym out of the epic genre, and its notice in Longinus, who in his commentary only quotes technical authors used as direct sources, have led us to propose a textual correction, Διονύσιος ὁ μουσικός, which, as I shall try to prove, is paleographically plausible and consistent from the point of view of the identification.
