The earliest member of m is Laurentianus gr. 32.9 (AD 960–80), shown above, the oldest and possibly the best source, equipped with glosses, variant readings and scholia, which contains, as well as the Argonautica, the seven tragedies, respectively, of Aeschylus and Sophocles. It shows signs of having been copied from an exemplar and then corrected from a second codex.
