SGG 1 offers the first critical edition of, and commentaries on, the textual fragments of the ancient Greek grammarians Antidorus, Dionysius Iambus, Epigenes, Lysanias, Parmenon, Silenus, Simaristus, and Sim(m)ias. All of these personalities belong, or so plausibly appear, to the early Hellenistic period (3rd-2nd centuries BC) and share a special interest in glossographical issues (mainly discussions of problems concerning lexical usages and customs, in Greek literature as well as in ordinary life of their times) and/or in literary history. Each entry includes: a biographical and cultural profile of the grammarian; the text of testimonies and fragments critically edited, translated, and analytically commented on; a thorough bibliography; and indices. Translation, critical apparatus, and commentary are in Italian.
