The Deeds of the Dukes of Normandy

The Gesta Normannorum Ducum [The Deeds of the Dukes of Normandy] is a landmark medieval chronicle tracing the rise and fall of the Norman dynasty from its early roots through the pivotal events surrounding the Norman Conquest of England. Originally penned in Latin by the monk William of Jumièges shortly before 1060 and later expanded at the behest of William the Conqueror, the work chronicles the deeds, politics, battles, and leadership of the Norman dukes, especially William’s own claim to the English throne. The narrative combines earlier historical sources with firsthand information and oral testimony to present an authoritative account of Normandy’s transformation from a Viking settlement into one of medieval Europe’s most powerful realms. William’s history emphasizes the legitimacy, military prowess, and governance of the Norman line, framing their expansion, including the conquest of England, as both divinely sanctioned and noble in purpose. Later chroniclers such as Orderic Vitalis and Robert of Torigni continued the history, extending the coverage into the 12th century, providing broader context on ducal rule and its impact. Today this classic work remains a foundational source for understanding Norman identity, medieval statesmanship, and the historical forces that reshaped England and Western Europe between 800AD and 1100AD.

In 1225 Robert de Ros (age 53), Baron of Wark-on-Tweed, and his wife Isabella, daughter of King William I of Scotland, founded a leper hospital at Bolton [Map] dedicated to St Thomas the Martyr. The chaplains at the hospital were granted a licence to build a chapel at the hospital for their own use, and this seems to have been a way of restoring to use the existing church here. Less positively those running the hospital seem to have been amongst the earliest Border reivers, as in 1285 the master and a number of the chaplains were accused of burning houses and stealing goods in the village of Branxton, close to the Scottish border.

Before 12th December 1226 Robert Ros (age 54) died. He was buried at Temple Church, London [Map].

Effigy of Robert Ros. [Robert Ros] WAS descended from the noble family of Ros or Roos, of Hamlake. His father Everard died when he was thirteen years of age, and he had livery of his lands from the wardship of the Crown in the second year of the reign of Richard I. on payment of a hne of one thousand marks; which shows that his possessions must have been very large.

He was one of the Barons who leagued together to obtain the Great and the Forest Charter from John; and when that King had signed them at Runnemede, he was one of the chief persons who undertook to constrain him to observe thema He married [his wife] Isabella, the daughter of [his father-in-law] William the Lion, King of Scotland, by whom he had two sons, William and Robert. He gave the first his castle of Helmesley [Map], with the patronage of the monasteries of Kirkham, Rievaulx [Map], and Warden, to the other his castle of Werke and a barony in Scotland, held by knight's service of his brother-in-law. Of both the above-mentioned castles he was the founder. He confirmed to the Templars his manor of Ribstone, with other possessions, assumed the habit of their order, died in 1231, and was buried in the Temple church [Map]. The effigy of Ros is cross-legged, and his hands raised in the act of prayer; the hood of his hauberk is thrown back to show his visage. His sword depends from a belt adorned with broad studs; his surcoat reaches to his heels, which are armed with the pryck spur, and rest on a lion. On his shield are three water bougets, which were the bearing of Ros, Argent, in a held Gules. This figure, like that of Robert de Vere, is of a period subsequent to that of the decease of the person whom it is said to represent.
