Cicero, On Divination 2.115-6
Cicero is discussing ambiguous oracles, and gives a Latin hexameter version of the Greek hexameter Κροῖσος Ἅλυν διαβὰς μεγάλην ἀρχὴν καταλύσει (which appears in indirect statement at Herodotus 1.53).
nam cum illa sors edita est opulentissumo regi Asiae:
Croesus Halyn penetrans magnam pervertet opum vim
hostium vim se perversurum putavit, pervertit autem suam: utrum igitur eorum accidisset, verum oraclum fuisset.
For when that oracle was given to the most wealthy king of Asia – ‘If Croesus crosses the Halys he will overturn the great power of an empire’ – he thought that he would overturn his enemies’ power, but he overturned his own. Therefore, whichever of these outcomes had happened, the oracle would have been true!
