Around 1075, the French priest Jocundus was commissioned by the chapter of Saint Servatius to write another "Vita sancti Servatii". Jocundus is also the author of the "Miracula sancti Servatii", a sequel to the vita, describing all the miracles that happened after Servatius' death. According to some historians, both works were composed to quell doubts about the genealogy of Servatius and his Armenian descent. These doubts had been raised at the Council of Mainz in 1049. When envoys from the Byzantine emperor arrived at the Council of Mainz, confirming accounts by a certain Alagrecus who had testified that Servatius was Armenian, and asserting that his birthplace was "Fenuste", southeast of Damascus, this helped to erase some doubts but Servatius' kinship to Jesus was never confirmed by an official council.
