Task: Question Generation
Input (English): Passage: In 1550, the Norwich authorities decreed that in future 27 August should be a holiday to commemorate "the deliverance of the city" from Kett's Rebellion, and paid for lectures in the cathedral and parish churches on the sins of rebellion. This tradition continued for over a century. The only known surviving eye-witness account of the rebellion, a manuscript by Nicholas Sotherton, son of a Norwich mayor, is hostile towards the rebels. So too is Alexander Neville's 1575 Latin history of the rebellion, De furoribus Norfolciensium. Neville was secretary to Matthew Parker, who had preached to Kett's followers under the Oak of Reformation on Mousehold, unsuccessfully appealing to them to disperse. In 1615 Neville's work was translated into English by Norfolk clergyman Richard Woods under the title Norfolke Furies and was reprinted throughout the following century. Kett's name was thus kept alive as a "reviled symbol of rustic violence". It was only in the 19th century that more sympathetic portrayals of the rebellion appeared in print and started the process that saw Kett transformed from traitor to folk hero. An anonymous work of 1843 was critical of Neville's account of the rebellion, and in 1859 clergyman Frederic Russell, who had unearthed new material in archives for his account of the rebellion, concluded that "though Kett is commonly considered a rebel, yet the cause he advocated is so just, that one cannot but feel he deserved a better name and a better fate".
Output (English): Approximately how many centuries passed before Kett was thought of in a more sympathetic way?
