Virgil's Aeneid

My theme is war and a particular man - a man driven by destiny to abandon Troy and sail to western Italy to fulfill his fate of founding the people who would build Rome. Fulfilling his destiny was not easy. Juno, the wife of Jupiter, the king of gods and men, opposed him, as did many warriors. They did not want him to bring his household gods - the Penates - to Latium on the western coast of Italy, to marry Lavinia, to found the city of Lavinium, and to become the ancestor of the Romans.
Muse, remind me of the reasons why Juno hated Aeneas, a man renowned for his pietas, for his devotion to duty, whether to the gods, to his family, or to his destiny. Aeneas had respect for those things to which respect is due. Why did Juno make his fulfilling his destiny so difficult? Are the immortals capable of such anger?
