Jehan Creton accompanied Richard II on his expedition to Ireland in 1399 and witnessed his capture by Henry Lancaster, who usurped the throne to reign as Henry IV. Creton's account is of crucial importance for historians of the period, as he contradicts the official version of events in the Parliamentary Roll. Until now, historians have had to rely on a 200-year-old edition by an antiquarian with no specialist knowledge of Middle French: the Rev. Webb's edition of 1824 has all the disadvantages of a publication of that era. Creton's other known writings - the two epistles and four ballades - are edited here and his debt to Valerius Maximus in the epistle to the duke of Burgundy is identified for the first time. A complete translation has been added, plus quality reproductions of the original miniatures which Creton specified as an integral part of his work.
