Final answer:
Jove (Jupiter) agreed to Calypso releasing Ulysses due to the persuasiveness and joint influence of the gods, with Minerva (Athena) playing a key role, and Mercury (Hermes) acting as messenger.
Step-by-step explanation:
In Homer's The Odyssey, Jove (Jupiter) agrees to Calypso releasing Ulysses due to the intervention and persuasiveness of other gods, especially Minerva (Athena). The gods, through their joint influence and authority, considerably pressured Jupiter, who is often reluctant when it comes to meddling in the destinies of men. Additionally, Mercury (Hermes), the messenger of the gods, is frequently depicted in literature as facilitating communications between gods and mortals, and this would be consistent with his offered role in convincing Calypso to free Ulysses.
