CCCC MS 285 contains the holograph copy of the Vita Henrici V regis Angliae of Tito Livio Frulovisi (d. after 1456), a biography of the Lancastrian king that, it has recently been argued, was a reworking of the pseudo-Elmham's Vita et Gesta Henrici Quinti. Written while Frulovisi was in England in the later 1430s, perhaps 1436-8, the manuscript was once in the possession of Henry VI, though how it came to be in Parker's possession is not known. It was presumably Parker who bound this fifteenth-century humanist text together, somewhat incongruously, with a tenth- or early eleventh-century copy of De laudibus uirginitatis (De virginitate) by Aldhelm (d. 709) to which have been added glosses in a hand identified with a Worcester Cathedral scribe.
