Quintilian (about 35-95 AD) was a famous orator and educator during the Roman Empire. He was born in Spain, and his father taught eloquence in Rome, which is quite famous. When quintilian was a teenager, he went to Rome with his father to study and receive eloquence education. He has been a lawyer for 10 years. In 70 AD, he was appointed as the director of a national Latin rhetoric school. Because of his attainments in eloquence and outstanding achievements in running a school, he became the first teacher of the lecture when the Roman Empire set up a lecture on eloquence paid by the state in 78 AD. Like Cicero, he thinks that an ideal speaker must be a kind person first, and a moral life is much more important than flowery rhetoric. He has great confidence in education and believes that educators should see that children have unlimited potential and development possibilities. Of course, talent is very important in learning, but we can't complain that only a few people have the ability to receive education, and most people are slow. On the contrary, most people understand quickly and are willing to learn. Stupid people are very few things that like to be abnormal. He strongly advocated and demonstrated that public education is superior to private education. He asked future speakers to live in the most open and sunny public life and be good at communicating with the society in order to be constantly stimulated and encouraged. In learning, he believes that as an orator, you must have a broad and solid knowledge base. He particularly emphasized the importance of literature teaching (including studying the works of historians, scientists and poets). He said, "unless a good and real foundation is laid, the superstructure will collapse."

Quentin worked in Latin rhetoric school for about 20 years and retired around 90 AD.

While serving as a teacher, quintilian also serves as a lawyer, which enables him to enrich the teaching content with his rich practical experience as a lawyer and closely combine theory with practice.

After retiring, quintilian devoted himself to writing. After more than two years of hard work, I wrote "Principles of Eloquence" (12 volume, about 650,000 words in Chinese). This book is not only a summary of his own education and teaching experience for about 20 years, but also a master of education experience in ancient Greece and Rome. Quintilian's educational theory and practice aim at cultivating speakers.

Principles of oratory was written in 96 AD, but it was lost. During the Renaissance, quintilian's long-lost works were rediscovered from the dust (Principles of oratory was rediscovered in 14 16), which immediately dazzled humanists.

Principles of oratory is the first book in ancient western countries that systematically discusses teaching methods. In this book, quintilian summed up his successful teaching experience and the successful experience of educational practice in the ancient western world, especially in teaching methods, which not only reflected the reality of school education in Rome around 200 AD, but also systematically expounded his educational thought of cultivating public speakers. It occupies an important position in the history of education.
