In this episode a Light approaches Dante and starts speaking in Latin. This turns out to be his great-great grandfather, Cacciaguida, the father of Alighiero (who is in Purgatory). He represents strength and endurance in this sphere, and tells us about the story of the Old Florence and his life as a warrior.

Overall themes are the generosity of true love vs. the immoralities of the self-serving love, music as a divine language, and the centrality of lineage and heritage.

Enjoy!
