The author of On the Orators is: Cicero.

Cicero was an outstanding orator and educator in Rome. His representative work is "On the Orators". Cicero believes that virtue is the primary quality of an orator. The most essential characteristic of an orator is the ability to speak appropriately on any issue.

On the quality of orators and their educational content:

1. An orator should have the innate ability to become an orator. Such as the ability to respond quickly intellectually, quick eloquence, crisp voice, well-proportioned body and other inherent qualities in human nature.

2. An orator should have a broad and solid knowledge base and ethical character. Cicero believed that to be a successful orator, one should not just be a behind-the-scenes compromiser full of cunning and debating skills, but must have a broad and solid knowledge base.

3. Orators should have language literacy. Cicero believed that as a true orator, it is not enough to have general knowledge of nature and society, but must also have special cultivation in language, because the choice of words and sentences and the stylistic structure of the entire speech determine the level of the speech.

4. An orator should have elegant manners and grace. Cicero believed that body posture, gestures, facial expressions and changes in tone of voice during speeches would all play a huge role in the effectiveness of the speech.

On the methods of cultivating orators:

1. Enable orators to have extensive knowledge through extensive reading.

2. Through long-term writing, orators can acquire sharp thinking, judgment and witty expression, thereby improving their "eloquence".

3. Improve the orator’s eloquence theory and skills through a large amount of practical training.
