The following is a leaf from an English version of Polychronicon printed by Peter Treveris and published by John Reynes.
Polychronicon is a history of the world written by a Benedictine monk Ranulf Higden (d. 1364) in the first half of the fourteenth century. Its original is in Latin, while it was translated into Middle English by John Trevisa in the latter half of the fourteenth century. Trevisa's translation was printed and published by William Caxton in 1482 (see this page), and was reprinted by Wynkyn de Worde in 1495.
This leaf is from a volume printed in 1527 by Peter Treveris (fl. 1525-32) for John Reynes (d. 1545). It is also based on Trevisa's translation. Treveris's edition is an illustrated one and is said to be important for its woodcuts. It is also known that it includes the earliest printed depiction of musical notation in an English book.
This leaf contains a woodcut initial, and covers from the last part of Book 7 Chapter 21 to the beginning of the next chapter, from 1153 to 1155, and mentions the death of St Bernard, the death of King Stephen, and the accession of King Henry I. It also includes some contemporary marginal notes and underlining in ink.
