As testified by a fragment, which survived in the oeuvre of Charisius, a grammarian from the late Antiquity, L. Annaeus Cornutus dedicated his critical work on Virgil to Silius Italicus, the author of the epic entitled Punica, who belonged to Nero's circle of literati in his youth. Given the knowledge of the history of Nero's literary circle and the findings of a careful examination of the fragment, it can be assumed that this work of Cornutus, which might have been quoted by Pliny the Elder in his Dubius sermo, was probably written and published in the early 60s (A.D.).
