Ragnhard I, King of Cambrai

Roi de Cambrai

Ragnhard, roi de Cambrai

Gregory of Tours relates that Ragnacaire, king of Cambrai, had a favorite by the name of Farron with whom he shared morals so uncomfortable that Clovis, having heard of his behavior, decided to put an end to it by raising the leudes of Ragnacaire against their King. Ragnacaire was taken prisoner with his brother Riquier. Clovis killed them with an ax, then got rid of the third brother, whom he had killed at Le Mans. This third brother is named Renomer by Gregory of Tours, name corrected most often in Rignomer or Ragnomer, even Richomer. As for the location of the kingdom of Rignomer, it is subject to debate. Godefroid Kurth believes that Clovis would never have allowed a Frankish prince to carve a kingdom at Le Mans after the conquest of northern Gaul, that Rignomer had the royal title as a male member of the royal family and that he was killed at Le Mans without being the king, but the contemporary historian Michel Rouche think that Aegidius, father of Syagrius, had installed Rignomer as military leader and governor of Mans
