Grammarians of antiquity taught and practiced philology, text criticism and rhetoric, essential skills in the education, career and public life of ancient Greeks and Romans. Brill’s Lexicon of Greek Grammarians of Antiquity (LGGA) serves as the first point of reference for information on these ancient grammarians for scholars of Greek and Latin antiquity, in particular for research into the history of philology, grammar and ancient scholarship. Sorted alphabetically by Latin name, each entry consists of 1) an introduction with biographical information on the respective grammarian, as well as a discussion of his work and preserved fragments; 2) the Greek text of these fragments; and finally 3) the relevant bibliography, including lists of editions (if any) and studies. A total of more than 570 grammarians have been identified for inclusion in the LGGA and about 300 will be available in the first publication online. Each entry will be published in Italian and English and the publication will be complete in 2019.
