Ranulf Higden or Higdon (c. 1280 – 12 March 1364) was an English chronicler and a Benedictine monk of the monastery of St. Werburgh in Chester. He is believed to have been born in the West of England, taken the monastic vow (Benedictine), at Chester in 1299, and travelled over the north of England.
Higden was the author of the Polychronicon, a long chronicle, one of several such works of universal history and theology. It was based on a plan taken from Scripture, and written for the amusement and instruction of his society. It closes the long series of general chronicles, which were soon superseded by the invention of printing. It is commonly styled Polychronicon, from the longer title Ranulphi Castrensis, cognomine Higden, Polychronicon (sive Historia Polycratica) ab initio mundi usque ad mortem regis Edwardi III in septem libros dispositum. The work is divided into seven books, in humble imitation of the seven days of Genesis, and, with exception of the last book, is a summary of general history, a compilation made with considerable style and taste. Written in Latin, it was translated into English by John of Trevisa (1387), and printed by Caxton (1480), and by others. For two centuries it was an approved work.
It seems to have enjoyed considerable popularity in the 15th century. It was the standard work on general history, and more than a hundred manuscripts of it are known to exist. The Christ Church manuscript says that Higden wrote it down to the year 1342; the fine manuscript at Christ's College, Cambridge, states that he wrote to the year 1344, after which date, with the omission of two years, John of Malvern, a monk of Worcester, carried the history on to 1357, at which date it ends.
