Rethoric is one of the most important elements of the Roman education. It first appears in Greece and then in Rome. Cicero's speech was definately a model for writing fictious speeches held in the Senate. Each of the speeches had to onclude introduction, the main part and the conclusion. Besides, it contained good arguments and counter – arguments, as well as clear message which aimed at convincing the listener to believe at what had been said. Historiographers inserted these speeches into their works as monolouges of famous persons. In this way they rethorized their works. When composing a speech, it was equally important to know the history, as well as the rethorical structure. Although these speeches did not take place in the Senate and in front of a large auditorium their aim was to entertain the reader. They are direct, but of a subjective character because of the author's personal approach. Each of them gives a psychological characterisation of the character and the historical circumstances of the past.
