Between the hypothetical Peisistratean edition and the Vulgate recension of the Alexandrines is a historical gap. Fick's work indicates a connection, which also is suggested by the peripatetic associations of the Library of Alexandria (below). Moreover, some of the D-scholia redated to the 5th century BCE indicate that some sort of standard Iliad existed then, to be taught in the schools. These broad events are circumstantial evidence only. Nagy says, “As of this writing, Homeric scholarship has not yet succeeded in achieving a definitive edition of either the Iliad or the Odyssey.”
