Although it’s generally admitted that Virgil died on the 21th of September –19, the possibility that it was on the 22th of September (Donatus auctus) cannot be ruled out. By a strange coincidence, it would have been just the day before Augustus’ birthday : see Hor. Epist. 1 . 5 (Bibliography, item n° 35, pp. 162 ff.).
