The earliest educational monograph in the West is the cultivation of speakers by quintilian, an ancient Roman philosopher.

Quintilian was a famous educator in ancient Rome. He is a pioneer in greatly developing and perfecting educational methods and ideas in the history of education. He advocates that the education of children should be encouraging and can stimulate their interest.

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. It not only reflects the reality of Roman school education in the 200 years around A.D., but also systematically expounds the educational thought of cultivating orators.
