The Pearl Manuscript, also known as the Gawain manuscript, is an illuminated manuscript produced somewhere in northern England in the late 14th century or the beginning of the 15th century. It is one of the best-known Middle English manuscripts, the only one containing alliterative verse solely, and the oldest surviving English manuscript to have full-page illustrations. It contains the only surviving copies of four of the masterpieces of medieval English literature: Sir Gawain and the Green Knight, Pearl, Cleanness, and Patience. It has been described as "one of the greatest manuscript treasures for medieval literature", and "the most famous of all romance manuscripts".

The Cotton or Cottonian library is a collection of manuscripts that came into the hands of the antiquarian and bibliophile Sir Robert Bruce Cotton MP (1571–1631). The collection of books and materials Sir Robert held was one of the three "foundation collections" of the British Museum in 1753. It is now one of the major collections of the Department of Manuscripts of the British Library. Cotton was of a Shropshire family who originated near Wem and were based in Alkington and employed by the Geneva Bible publisher, statesman and polymath Sir Rowland Hill in the mid 16th century.
