40 But neither shall we deny that we know this as well, that once on a time, when the state and republic were in difficulties, caused either by a terrible plague continually infecting the people and carrying them off, or by enemies powerful, and at that time almost threatening to rob it of its liberty because of their success in: battle—by order and advice of the seers, certain gods were summoned from among nations dwelling beyond the sea, and honoured with magnificent temples; and that the violence of the plague abated, and very frequent triumphs were gained, the power of the enemy being broken, and the territory of the empire was increased, and provinces without number fell under your sway.
But neither does this escape our knowledge, that we have seen it asserted that, when the Capitol was struck by a thunderbolt, and many other things in it, the image of Jupiter also, which stood on a lofty pillar, was hurled from its place. Thereafter a response was given by the soothsayers, that cruel and very sad mischances were portended from fire and slaughter, from the destruction of the laws, and the overthrow of justice, especially, however, from enemies themselves belonging to the nation, and from an impious band of conspirators; but that these things could not be averted, nay, that the accursed designs could not be revealed, unless Jupiter were again set up firmly on a higher pillar, turned towards the east, and facing the rays of the rising sun.
Their words were trustworthy, for, when the pillar was raised, and the statue turned towards the sun, the secrets were revealed, and the offenses made known were punished.
