[LXXIII.] Trivia here refers to Diana. Gradivus is an archaic Latin name for Mars.
[LXXVII.] 'Mute Amyclae' was probably so called because the inhabitants had been forbidden, owing to false alarms, to speak of the approach of an enemy. But if Virgil is referring, not to the Amyclae near Naples, but to the original Amyclae in Laconia, then the proverbial taciturnity of those inhabiting the latter country offers sufficient explanation. Aegeon was a monster with 100 arms and 50 heads. He is more often called Briareus.
[LXXIX.] In the Iliad Aeneas had been rescued from Diomedes and Achilles. Liger is taunting him with this.
