M. Tullius Cicero Pro Q. Roscio Comoedo 24

[24] Would you even do this, O Fannius? And if you were able to receive such profits, would you not act with all your gestures, and even at the risk of your life? Say now that you have been cheated of fifty thousand sesterces by Roscius, who has refused such enormous sums, not because he was too indolent to labour for them, but out of a magnificence of liberality. What now shall I say of these things which I know to a certainty occur to your minds, O judges? Roscius cheated you in a partnership. There are laws, there are formularies ¹ established for every case, that no one may make a blunder, either as to the legal description of injury which he has suffered, or as to the sort of action he should bring; for public formulae have been given by the praetor to suit every evil, or vexation, or inconvenience, or calamity, or injury which any one can suffer and to them each private action is adapted.
