AP Latin Project Passage #3 this year is Ovid’s version of “Arion and the Dolphin” from his Fasti poem, a didactic poem about the holidays and festivals of the Roman calendar. Interestingly enough, Pliny the Younger has a famous letter about friendly dolphins near a North African tidepool (Pl. Ep. 9.33) and Aulus Gellius also wrote a version of the story (possibly based on an earlier tradition) in his Attic Nights (Noctes Atticae 16.19).
As with previous project passage, Passage 3 includes three tiers of increasing complexity, along with vocabulary glosses on the right-hand margin.
