The Institutio Oratoria is considered one of the most important works on rhetoric and education ever written. It covers a wide range of topics, including:
* The nature of rhetoric
* The training of the orator
* The art of speaking
* The development of character
* The role of the orator in society
Quintilian's work is still studied today by students of rhetoric, education, and classical literature. He is considered one of the most influential figures in the history of Western education.
While Institutio Oratoria is his most well-known work, Quintilian also wrote several other works, including:
* De Causis Corruptae Eloquentiae (On the Causes of the Decline of Eloquence)
* Declamationes (Speeches)
However, Institutio Oratoria is considered his magnum opus and is the one he is most remembered for.
