This edition makes available for the first time to a wider audience two historically important fifteenth-century English chronicles, with full scholarly apparatus and comprehensive introductions. 'The Dethe of the Kynge of Scotis' gives full and graphic accounts of the murder of James I of Scotland in 1437, and the subsequent executions of his assassins; translated from a lost Latin narrative by John Shirley, it is edited from the only full text that has survived. Warkworth's 'Chronicle', usually ascribed erroneously to John Warkworth, master of Peterhouse, Cambridge, is a frequently-cited source for events in the Wars of the Roses between 1461 and 1473, and gives a contemporary assessment of the supposed murders of Edward, Prince of Wales, and of Henry VI by Richard of Gloucester. The text is edited here (for the first time), from the original manuscript in which it occurs, although comparison of this manuscript and of two related manuscripts reveals a complex pattern of copying one from another and from books printed by Caxton. Professor LISTER M. MATHESON teaches at Michigan State University.
