The first was that of Janus Lascaris in 1517. It contained D-scholia of Porphyry. Some subsequent works concentrate on manuscripts or parts of them, others on type of scholia, and still others on books of the Iliad, or source. Larger compendia are relatively recent. One that has already become a standard is the 7-volume compendium of A- and bT-scholia by Hartmut Erbse. Volumes 15 are reserved for a number of books of the Iliad each, amounting to some 3000 pages, approximately. The last two volumes are indices. And yet, Dickey says of it. “The seven volumes of Erbse’s edition thus represent only a small fraction of all the preserved scholia …,” from which it can be seen that the opinions, elucidations and emendations to the Iliad and Odyssey in manuscript texts far outweigh those texts in numbers of pages.
