In footnote 39 to Dante's Il Convivio, Richard Lansing writes: “ Rome was founded, according to tradition,
on 21 April 753 B.C. For the references see Orosius, Historiarum adversus paganos libri septem VII, 3 and
Livy, History of Rome I, 18, a passage which Dante either did not read carefully or misremembered, since it
explicitly discredits the notion that Pythagoras lived in the time of Numa Pompilius (717-673 B.C.) [Return to text]
