For he needs some such reason as that to preserve him from feeling shame at entreating such a one as Antony. Again if we urge Gaius Caesar [*](Julius Caesar.) to accept the crown we shall assert that the state is doomed to destruction unless controlled by a monarchy. For the sole aim of the man who is deliberating about committing a criminal act is to make his act appear as little wicked as possible.
It also makes a great deal of difference who it is that is offering the advice: for if his past has been illustrious, or if his distinguished birth or age or fortune excite high expectations, care must be taken that his words are not unworthy of him. If on the other hand he has none of these advantages he will have to adopt a humbler tone. For what is regarded as liberty in some is called licence in others. Some receive sufficient support from their personal authority, while others find that the force of reason itself is scarce sufficient to enable them to maintain their position.
Consequently I regard impersonation as the most difficult of tasks, imposed as it is in addition to the other work involved by a deliberative theme. For the same speaker has on one occasion to impersonate Caesar, on another Cicero or Cato. But it is a most useful exercise because it demands a double effort and is also of the greatest use to future poets and historians, while for orators of course it is absolutely necessary.
For there are many speeches composed by Greek and Latin orators for others to deliver, the words of which had to be adapted to suit the position and character of those for whom they were
For a speech which is out of keeping with the man who delivers it is just as faulty as the speech which fails to suit the subject to which it should conform. It is for this reason that Lysias is regarded as having shown the highest art in the speeches which he wrote for uneducated persons, on account of their extraordinary realism. In the case of declaimers indeed it is of the first importance that they should consider what best suits each character: for they rarely play the role of advocates in their declamations. As a rule they impersonate sons, parents, rich men, old men, gentle or harsh of temper, misers, superstitious persons, cowards and mockers, so that hardly even comic actors have to assume more numerous roles in their performances on the stage than these in their declamations.
