Four sons of Aymon

The Four Sons of Aymon (French: [Les] Quatre fils Aymon, Dutch: De Vier Heemskinderen, German: Die Vier Haimonskinder), sometimes also referred to as Renaud de Montauban (after its main character) is a medieval tale spun around the four sons of Duke Aymon: the knight Renaud de Montauban, his brothers Guichard, Allard and Richardet, their magical horse Bayard , their adventures and revolt against the emperor Charlemagne. The story had a European success and echoes of the story are still found today in certain folklore traditions.

Dutch version Historie van den Vier Heemskinderen, the Dutch translation, dated 1508 and held at the University of Munich gives the following version: Duke Aymon, King of Pierlepont, thinks that Charles, his liege Lord, has not shown him gratitude enough when he gets only Dordogne (Dordoen) with the capital of Albi for his help in many of Charles’ wars. He is even angrier about the fact that his warrior-friend Hugh (Huon) de Narbonne gets nothing at all and decides to become renegade until Charlemagne gives him a suitable reward. In the end Charles adds: Aymons weight in gold and his sister Aye. Aymon is not truly satisfied and swears that he will kill any child born out of his union with the king’s sister. Aye rears her four sons (Richard, Writsaert, Adelhaert and Renout in this version) in secret at Pierlepont until the day that Aymon tells her how he regrets the fact that they have no offspring. She shows him his sons and Aymon is very impressed with Renaud who is of great height, feisty and strong. He gives Renaud the horse Bayard. The horse is so big that it can carry the four brothers on its back. When the four brothers are presented at Charles’ court in Paris Renaud kills Charles’ son Louis. They flee to the court of King Loup de Gascogne who betrays them to Charles. They escape their pursuers with the help of King Son of Aquitaine, who gives his daughter Claire or Clarisse to Renaud to wife and the castle of Montauban. Charles attacks the castle and after months of siege Renaud has to surrender. The cost of their survival is the drowning of his horse Bayard. Charles urges Renaud to go on a pilgrimage to the Holy Land, especially Jerusalem. When Renaud comes back he helps to build the shrine of St.Peter in Cologne. Envious men kill him and throw his body in the River Rhine.
