Q: Passage: Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" those who had sided with Simon de Montfort, 6th Earl of Leicester.

Q: Passage: The festival originated from the Cold Food or Hanshi Festival which remembered Jie Zitui, a nobleman of the state of Jin (modern Shanxi) during the Spring and Autumn Period. Amid the Li Ji Unrest, he followed his master Prince Chong'er in 655 to exile among the Di tribes and around China. Supposedly, he once even cut meat from his own thigh to provide his lord with soup. In 636, Duke Mu of Qin invaded Jin and enthroned Chong'er as its duke, where he was generous in rewarding those who had helped him in his time of need. Owing either to his own high-mindedness or to the duke's neglect, however, Jie was long passed over. He finally retired to the forest around Mount Mian with his elderly mother. The duke went to the forest in but could not find them. He then ordered his men to set fire to the forest in order to force Jie out. When Jie and his mother were killed instead, the duke was overcome with remorse and erected a temple in his honor. The people of Shanxi subsequently revered Jie as an immortal and avoided lighting fires for as long as a month in the depths of winter, a practice so injurious to children and the elderly that the area's rulers unsuccessfully attempted to ban it for centuries. A compromise finally developed where it was restricted to 3 days around the Qingming solar term in mid-spring.
