Note 284 — THE PROPHECY OF DANTE.
Reading edition
[The Panther, the Lion, and the She-wolf, which Dante encountered on the "desert slope" (Inferno, Canto I. lines 31, sq.), were no doubt suggested by Jer. v. 6: "Idcirco percussit eos leo de silva, lupus ad vesperam vastavit eos, pardus vigilans super civitates corum." Symbolically they have been from the earliest times understood as denoting—the panther, lust; the lion, pride; the wolf, avarice; the sins affecting youth, maturity, and old age. Later commentators have suggested that there may be an underlying political symbolism as well, and that the three beasts may stand for Florence with her "Black" and "White" parties, the power of France, and the Guelf party as typically representative of these vices (The Hell of Dante, by A. J. Butler, 1892, p. 5, note).
Count Giovanni Marchetti degli Angelini (1790-1852), in his Discorso ... della prima e principale Allegoria del Poema di Dante, contributed to an edition of La Divina Commedia, published at Bologna, 1819-21, i. 17-44, and reissued in La Biografia di Dante ... 1822, v. 397, sq., etc., argues in favour of a double symbolism. (According to a life of Marchetti, prefixed to his Poesie, 1878 [Una notte di Dante, etc.], he met Byron at Bologna in 1819, and made his acquaintance.)]
