The occasion for this collection of papers is the centenary of the publication of "The Scholia on the Aves of Aristophanes" by John Williams White (Boston-London 1914), a book that played a seminal role in setting the debate on the circumstances, manner and era of the birth of scholiography in the Greek milieu. This issue includes an Introduction by F.M., eight contributions by Italian scholars, and Conclusions by Antonietta Porro. Ancient authors and works concerned are (scholia on) Homer, Aeschylus, Aristophanes, mathematical Greek treatises, John of Scythopolis’ commentary on the Corpus Dionysiacum, Latin scholia to Virgil.
