Note d — Chapter IX · [a] (continued 4)
Reading edition
The source from which Dante derived the scheme and general idea of his poem has been a subject of inquiry in Italy. To his original mind one might have thought the sixth Æneid would have sufficed. But besides several legendary visions of the 12th and 13th centuries, it seems probable that he derived hints from the Tesoretto of his master in philosophical studies, Brunetto Latini. Ginguené, t. ii. p. 8.
