After a long imprisonment, Denis and two of his clergy were executed by beheading on the highest hill in Paris (now Montmartre), which was likely to have been a druidic holy place. The martyrdom of Denis and his companions is popularly believed to have given the site its current name, derived from the Latin Mons Martyrum "The Martyrs' Mountain", although the name is possibly derived from Mons Mercurii et Mons Martis, Hill of Mercury and Mars. After his head was cut off, Denis is said to have picked it up and walked several miles from the summit of the hill, preaching a sermon the entire way, making him one of many cephalophores in hagiology. Of the many accounts of this martyrdom, this is noted in detail in the Golden Legend and in Butler's Lives Of The Saints. The site where he stopped preaching and actually died was marked by a small shrine that developed into the Basilica of Saint-Denis, which became the burial place for the kings of France. Another account has his corpse being thrown into the Seine, but recovered and buried later that night by his converts. Veneration Veneration of Denis began soon after his death. The bodies of Denis, Eleutherius, and Rusticus were buried on the spot of their martyrdom, where the construction of the eponymous basilica was begun by Genevieve, assisted by the people of Paris. Her Vita Sanctae Genovefae attests the presence of a shrine near the present basilica by the close of the fifth century. Dagobert I, great-grandson of Chlothar I, had the first Royal Basilica built. The Merovingian tradition was, originally, to bury kings such as Clovis and Chlothildis in Paris at Abbey St-Genevieve/Genovefa, as Clovis had ordered its construction in 502 AD. Yet Chilperic I had his own mother, Dowager Queen Aregunda, buried at Saint-Denis. His grandson was clearly following a family tradition. Aregunda's (death about 580 AD) tomb was discovered in 1959, and her burial items can be seen at the Saint-Germain-en-Laye museum. A successor church was erected by Fulrad, who became abbot in 749/50 and was closely linked with the accession of the Carolingians to the Merovingian throne. In time, StDenis came to be regarded as the patron saint of the French people, with StLouis the patron of the monarchy and royal dynasties. Saint Denis or Montjoie!
