Eurilla tells Mirtillo that his love is on her way and he should go into the nearby cave and wait for her, which he does. Eurilla then fetches Amarilli and tells her she can watch what Mirtillo is up to with the other girl from inside the same cave, and leads Amarilli into it too. Now that the two are in the cave together, Eurilla will go and tell the law authorities to arrest them for illicit sex, for which Arcadian law prescribes death for the female partner, Amarilli will be executed, and then Eurilla will have Mirtillo for her own.
