Institutio Oratoria

Quantity also, as I have already stated, [*](§ 16.) falls as a rule, though not always, under the head of quality, whether it is concerned with measure or number. Measure, however, sometimes consists in the valuation of a deed with a view to determining the amount of guilt or the amount of benefit involved, while, on the other hand, it sometimes turns on a point of law, when the dispute is under what law a man is to be punished or rewarded.

For example is a ravisher to pay 10,000 sesterces [*](cp. IV. ii. 69. ) because that is the penalty appointed by law, or is he liable to capital punishment as a murderer because his victim hanged himself? In such cases those who plead as if there were a question between two laws, are wrong: for there is no dispute about the fine of 10,000, since it is not claimed by the prosecution.
