Commentary Par VI 4-6

Dante's chronology is different from that of most historians; he perhaps reflects one tradition found in some manuscripts of Brunetto Latini's Tresor, which has it that the initial transfer took place in 333 (and not in 330), and that Justinian assumed the eastern throne only in 539 (and not in 527), some 206 years later, thus accounting for Dante's error (in verse 4: 'two hundred years and more').  For speculation regarding these dates in relation to Dante's sense of imperial prophecy in the Aeneid, see Hollander and Russo (Holl.2003.1).

The mountains of the Troad, in Asia Minor, are presented as the site of Troy.
