Institutio Oratoria

Cicero in the pro Cluentio [*]( xxxvi. 98. The lex Iulia de ambitu contained a provision that the penlty (loss of civil rights) incurred by conviction for ambitus should be annulled if the condemned man could secure the conviction of another person for the same offence. ) says that Publius Popilius and Tiberius Gutta were not condemned for receiving bribes to give a false verdict, but for attempting to bribe the jury. What is his argument in support of this view? That their accusers, who were themselves found guilty of bribing the jury, were restored in accordance with law after winning their case.

But the consideration as to what argument should be put forward requires no less care than the consideration of the manner in which we are to prove that which we have put forward. Indeed in this connexion invention, if not the most important, is certainly the first consideration. For, just as weapons are superfluous for one who does not know what his target is, so too arguments are useless, unless you see in advance to what they are to be applied. This is a task for which no formal rules can be laid down.

When Alexander destroyed Thebes, he found documents showing that the Thebans had lent a hundred talents to the Thessalians. These documents he presented to the Thessalians as a reward for the assistance they had given him in the campaign. Subsequently the Thebans, after the restoration of their city by Cassander, demanded that the Thessalians should repay the money.

The whole dispute turns on the allegation that Alexander had excused the Thessalians from payment of the debt. It is also admitted that the Thessalians had received no money from Alexander. The question is therefore whether his gift is equivalent to his having given them money.
