Diomede grammatico: fonti, tradizione manoscritta, circolazione e ricezione della sua opera. Edizione critica di una sezione del capitolo ‘De verbo’ (GL I 364-388)

This work offers the critical text and commentary of a portion of Book I of Diomedes’ Ars, corresponding to the dissertation about the formation of the perfect, defective verbs and some irregular verbs (GL I 364, 10-388, 10). The introduction, organized in five chapters, offers first of all some issues concerning the author (chapter I) and his work in general, and an overview of its structure and contents, with particular attention to the characteristics related to its destination as a manual conceived for a Greek-speaking audience (chapter II). The third chapter is devoted to the manuscript tradition of the Ars, with a census of the witnesses that preserve it and a description of the manuscripts on which the recensio is based. The textual relationship between them is then discussed and a hypothesis of the reconstruction of the stemma codicum is offered. The chapter closes with a history of the circulation of Diomedes' text that illuminates some moments of its early medieval diffusion, as well as its rediscovery in the humanistic age. The fourth chapter of the introduction is specifically dedicated to the section of the work of which the edition is offered. The introduction closes with a formulation of the criteria of the critical edition. The critical text, corresponding to pages 364-388 of volume I of Keil's Grammatici Latini, is followed by a commentary that discusses textual and philological problems and at the same time deepens Diomedes' doctrine on certain questions of verbal morphology, comparing it with the rest of late antique and early medieval grammatical literature.
