Ovid uses mythological examples to prove his points - 'Menelaus has Helen, and Agamemnon has Clytaemnestra' 'Penelope was faithful' 'Alcestis, his wife, redeemed Admetus' life with her own' 'Jason left Medea' 'Aeneas, your guest, supplied the sword, Dido' 'Orpheus, with his lute, moved animals and stones' 'Procris should be an example to you' etc
