The oath of Aeneas and Latinus
Sol · Earth · Jupiter · Juno · Mars · Janus · Apollo · Diana · Dis Pater · the ManesThe twelfth book of the Aeneid: before the duel of Aeneas and Turnus the two sides conclude a treaty, and both swear. Both halves are given here, across the seam […]: first Aeneas speaks, then Latinus.
The list of witnesses is the fullest in Virgil. Sun, Earth, Jupiter, Juno, Mars, springs and rivers, "whatever is holy in the high aether and whatever divinities are in the blue sea"; in Latinus' half — earth, sea, stars, Latona's twin offspring, two-faced Janus, the powers below and Dis. This is the structure of an actual Roman treaty oath: heavenly, earthly, infernal, so that no tier is left before which the matter has not been filed. The same tripartition appears in the fetial formula (janus-004).
But the most human thing here is a parenthesis. Et tu Saturnia coniunx (iam melior, iam, diva, precor): and you, Saturnian consort — kinder now, now, goddess, I pray. Aeneas calls to witness the goddess who has been destroying him for twelve books, and in the middle of the address he breaks down and asks. Inside a legal formula, a voice breaks through.
He will keep the oath. The Latins will break it — Juturna will rekindle the fighting — and this whole assembly of witnesses will have been convened precisely so that the perjury may be committed in front of them. That is the point of the scene: the gods are summoned not to prevent but to see.
