Pallas (son of Evander)

In Roman mythology, Pallas (/ˈpæləs/; Ancient Greek: Πάλλας) was the son of King Evander.

In Virgil's Aeneid, Evander allows Pallas to fight against the Rutuli with Aeneas, who takes him and treats him like his own son Ascanius.

[3] Tragically, however, Pallas is eventually killed by Turnus,[4] who takes his sword-belt, which is decorated with the scene of the fifty slaughtered bridegrooms, as a spoil.

[5] Throughout the rest of Book X, Aeneas is filled with rage (furor) at the death of the youth, and he rushes through the Latin lines and mercilessly kills his way to Turnus.

[8] This drives Aeneas into another murderous rage, and the epic ends as he kills Turnus in revenge for Pallas' death.
