Adam Murimuth's Continuation and Robert of Avesbury’s 'The Wonderful Deeds of King Edward III'

This volume brings together two of the most important contemporary chronicles for the reign of Edward III and the opening phases of the Hundred Years’ War. Written in Latin by English clerical observers, these texts provide a vivid and authoritative window into the political, diplomatic, and military history of fourteenth-century England and its continental ambitions. Adam Murimuth Continuatio's Chronicarum continues an earlier chronicle into the mid-fourteenth century, offering concise but valuable notices on royal policy, foreign relations, and ecclesiastical affairs. Its annalistic structure makes it especially useful for establishing chronology and tracing the development of events year by year. Complementing it, Robert of Avesbury’s De gestis mirabilibus regis Edwardi tertii is a rich documentary chronicle preserving letters, treaties, and official records alongside narrative passages. It is an indispensable source for understanding Edward III’s claim to the French crown, the conduct of war, and the mechanisms of medieval diplomacy. Together, these works offer scholars, students, and enthusiasts a reliable and unembellished account of a transformative period in English and European history. Essential for anyone interested in medieval chronicles, the Hundred Years’ War, or the reign of Edward III.

Chronicle of William Rishanger. [1277].Furthermore, besides these things, the Prince [Llywelyn "Last" Aberffraw [aged 44]] will reconcile with his brothers, whom he had wronged. For he had three brothers, two of whom, Owen [aged 45] and Rhodri [aged 47], he had imprisoned; the third, David, having fled, stayed for many years with the King of England. By the King, and against the custom of his people, he was made a knight. In that war, due to his bravery and loyalty, he became highly esteemed by the King. As a result, the King granted him the castle of Denbigh in Wales, along with lands worth one thousand pounds in annual revenue; moreover, he gave him a wife [Elizabeth Ferrers [aged 37]], the daughter of the Earl of Derby, who had recently been widowed by another man [William Marshal]. Owen, then, through royal favor, was freed from the prison which he had recently broken. Rhodri, however, fled from his brother and resided in England. The King, moreover, built a significant castle at Aberystwyth [Map]1 in Western Wales, to suppress the raids of the Welsh.

Item, præter hæc, Princeps fratres suos, quos læsit, placabit. Habuit enim tres fratres, quorum duos, Owenum et Rodericum, posuerat in carcere; tertius vero, David, fuga dilapsus, multis annis cum Rege Angliæ stetit; a quo, contra morem gentis suæ, miles factus, in ista guerra, ob probitatem et fidelitatem suam, plurimum erat Regi acceptus: unde et eidem castrum de Dimby contulit in Wallia, cum terris ad valorem mille librarum annui redditus; insuper et uxorem dedit, filiam Comitis Derbeyæ, quæ nuper alio viro fuerat viduata. Owenus ergo favore regio liberatur a carcere, quem fregerat paulo ante. Rodericus vero, fratrem fugiens, in Anglia morabatur. Rex autem in Occidentali Wallia apud Lampader Vaur, ad cohibendum irruptiones Wallensium, castrum construxit insigne.
