National Library of Wales MS Brogyntyn ii.1, formerly known as Porkington 10, has long been treasured for the diversity and uniqueness of its texts. Only five of its fifty-seven texts are wholly in Latin; the fifty-two works wholly or mostly in Middle English are variously practical, devotional, and entertaining. They include most of the genres of vernacular writing, and the majority of them either occur in no other extant manuscripts (fifteen items) or appear in Brogyntyn ii.1 in uniquely altered versions (sixteen items). More recently, the extent to which the manuscript reflects the concerns of the gentry class has been highlighted; it seems to have been made for a gentleman, a newly specific term for the lowest rank of the gentry. Yet only a few of its texts have received attention from anyone other than their editors, and even fewer scholars have discussed the manuscript as a whole. Among the reasons for this relative neglect of the manuscript is that eleven scribal hands are found in it, an unusually large number compared to the miscellanies that have been studied most. Furthermore, no scribe or fifteenth-century owner has been identified; such anonymity is known to be a disadvantage for a miscellany in need of scholarly attention. Finally, Brogyntyn ii.1 is unusual among mis-cellaneous manuscripts because it is not divisible into booklets. These factors led us to realize that only collaboration can begin to answer the questions and solve the problems presented by this fascinating manuscript.
