Aeneas and his men have endured insurmountable hardships caused by Juno's wrath. Aeneas feels deeply unsettled and worried that they will not complete their mission, however, he hides this fear in order to inspire strength and courage in his people. Aeneas is a great leader because he puts the needs of his people before his own.

From the Greek and Trojan perspective, the gods could be either helpful or hurtful to men, depending on their whims. The gods, at least from Aeneas's view, are not dependable, which is why he puts more faith in his and his companions desire to survive so that their people can endure.
Virgil is referring to Aeneas's fear of Juno. Even though he is overwhelmed by the majesty of the city, he's still afraid of encountering Juno, who hates the Trojans.

A poignant moment that lends realism to the mythic tale. Aeneas, as the leader, has to appear confidant and upbeat to encourage his followers, but he has seen so many of friends die in the Trojan War and during the escape to Italy (Latium) that he is truly in despair. Virgil is humanizing this mythic hero by making him subject to emotional trauma.

Acestes, who lives in Sicily, is the son of the Sicilian river god Crimisus and a Trojan woman named Egesta. When Aeneas and the Trojan fleet stop in Sicily, Alcestes entertains them and helps supply their ships. Trinicria is a Latin poetic name for Sicily.
"The crown to King Latinus I resign:
His be the sov'reign sway. Nor will I share
His pow'r in peace, or his command in war.
For me, my friends another town shall frame,
And bless the rising tow'rs with fair Lavinia's name."

Aeneas makes this pact with King Latinus so that his people might live in peace and equality with the Latins. Unlike many other epic heroes, Aeneas does not want to conquer lands to demonstrate his power or glory, but rather wants to do what is best for his people. He shows compassion and honor in this treaty, along with a commitment to his duty. Aeneas set an example of what a hero and a leader should be, one after which the Romans modeled their civic duty and moral compass as the empire grew.
