For the accused either confines himself to denying that he did it or accuses another of having done it. Further, there is more than one way of transferring the charge to another. At times this results in mutual accusation, which the Greeks call ἀντικατηγορία, and some of our own authors concertative accusation. [*](i.e. mutual or reciprocal accusation, see VII. i. 3. ) At times, on the other hand, the charge is transferred to some person who cannot be brought to trial, and may be either known or unknown: again, if the person is known, he may be someone outside the case or the victim himself, who may be alleged to have committed suicide.
In such cases we compare characters, motives and other circumstances in the same way as in eases of mutual accusation. Cicero, for instance, in the pro Vareno diverts the charge from the accused to the slaves of Ancharius and in the pro Scauro throws the suspicion of Bostar's murder upon his mother.
There is also a different form of comparison, which comes into play when both parties claim the credit of some act, and yet another kind, when the question is not as between two persons, but as between two acts; that is to say, the question is not which of the two committed an act, but which of two acts was committed. Finally, if the act and the identity of the author are both
I have not committed adultery,
I have not sought to establish myself as tyrant.In cases of murder or poisoning the denial is often divided as follows:
The act was not committed, and, if it was committed, it was not by me.But if the defence say,
Prove that the man was killed,the burden falls solely on the accuser, for the accused can say nothing more against the charge except perhaps in the way of casting certain suspicions, which he should throw out in the vaguest terms, since if you make one definite assertion, you will have to prove it or run the risk of losing your case. For when the question lies between our statement and that of our opponent, one or other will be regarded as true. Thus when the point on which we relied for our defence is overthrown, there is nothing left but the points that tell against us.
For example, when the question turns on symptoms, which may point either to poisoning or internal disease, there is no third course left open and consequently each party sticks to his statement. At times the question turns on the nature of the fact, whether, for instance, death was due to poisoning or internal disease, and arguments are introduced which are drawn from the circumstances alone without any reference to the person concerned.
For example, it makes a difference whether the deceased was cheerful or depressed, had been working or taking his ease, had been awake or sleeping previous to the festive gathering that
