CCCC MS 313 contains a collection of historical texts copied in a late tweflth- or early thirteenth-century hand. The two major works in the manuscript are the Epitoma de Tito Livio of Lucius Annaeus Florus (fl. c. 140), an account of Roman history, and the Opuscula of Ralph de Diceto (d. 1199/1200), a work of history from the Incarnation to his own day comprised of extracts from his own and other authors' works. Although such material appealed to Parker, there is very little clues as to how this manuscript came into Parker's possession apart from the name 'Byny' written in Parker's characteristic red chalk on one of the flyleaves.
