The verse-by-verse commentary on the Ovidian text includes the reading of more than 300 manuscripts, including the so-called Heinsian manuscripts, and of almost 100 editions, from the two "editiones principes" of 1471 to the present day. The introduction describes the manuscripts used, and a history of the Ovidian editions is also traced. A new text of book VI is presented, accompanied by a slim and lucid critical apparatus. Futher information appears in the commentary and in the appendices, particularly readings of manuscripts and editions. The verbatim commentary offers, with reliable quotes for each term, the critical observations of all the editors and commentators of the Ovidian work throughout the centuries. This aspect of critical edition has been neglected by commentators of Ovid since Heinsius (1659) and Burman (1727). Two appendices ("Readings of manuscripts" and "Readings of editions") are added for the first time for readers of the Ovidian work. The volume closes with a "Select index of textual problems", a large "Index locorum" and an "Index nominum".
