still in use is the Menippean satire by Menippus of Gadara. His own writings are lost. Examples from his admirers and imitators mix seriousness and mockery in dialogues and present parodies before a background of diatribe. As in the case of Aristophanes plays, menippean satire turned upon images of filth and disease. Ancient China Satire, or fengci (諷刺) the way it's called in Chinese, goes back at least to Confucius, being mentioned in the Book of Odes (Shijing 詩經). It meant “to criticize by means of an ode”. In the pre-Qin era it was also common for schools of thought to clarify their views through the use of short explanatory anecdotes, also called yuyan (寓言), translated as "entrusted words". These yuyan usually were brimming with satirical content. The Daoist text Zhuangzi is the first to define this concept of Yuyan. During the Qin and Han dynasty, however, the concept of yuyan mostly died out through their heavy persecution of dissent and literary circles, especially by Qin Shi Huang and Han Wudi. Roman world The first Roman to discuss satire critically was Quintilian, who invented the term to describe the writings of Gaius Lucilius. The two most prominent and influential ancient Roman satirists are Horace and Juvenal, who wrote during the early days of the Roman Empire. Other important satirists in ancient Latin are Gaius Lucilius and Persius. Satire in their work is much wider than in the modern sense of the word, including fantastic and highly coloured humorous writing with little or no real mocking intent. When Horace criticized Augustus, he used veiled ironic terms. In contrast, Pliny reports that the 6th-century-BC poet Hipponax wrote satirae that were so cruel that the offended hanged themselves. In the 2nd century AD, Lucian wrote True History, a book satirizing the clearly unrealistic travelogues/adventures written by Ctesias, Iambulus, and Homer. He states that he was surprised they expected people to believe their lies, and stating that he, like them, has no actual knowledge or experience, but shall now tell lies as if he did. He goes on to describe a far more obviously extreme and unrealistic tale, involving interplanetary exploration, war among alien life forms, and life inside a 200 mile long whale back in the terrestrial ocean, all intended to make obvious the fallacies of books like Indica and The Odyssey. Medieval Islamic world Medieval Arabic poetry included the satiric genre hija.
