Iuturnam misero (fateor) succurrere fratri suasi et pro vita maiora audere probavi, non ut tela tamen, non ut contenderet arcum; adiuro Stygii caput implacabile fontis, una superstitio superis quae reddita divis.
As for Juturna, I counselled her, I own, to help her hapless brother, and for his lifes sake sanctioned still greater deeds of daring, but not to level the arrow, not to bend the bow: I swear by the inexorable fountainhead of Styx, sole name of dread ordained for the gods above.
