<P> Details of Mungo's infirmity have a ring of authenticity about them . The year of Mungo's death is sometimes given as 603, but is recorded in the Annales Cambriae as 612 . 13 January was a Sunday in both 603 and 614 . David McRoberts has argued that his death in the bath is a garbled version of his collapse during a baptismal service . </P> <P> In a late 15th - century fragmentary manuscript generally called' Lailoken and Kentigern', Mungo appears in conflict with the mad prophet, Lailoken alias Merlin . Lailoken's appearance at the Battle of Arfderydd in 573 has led to a connection being made between this battle, the rise of Riderch Hael and the return of Mungo to Strathclyde . </P> <P> The Life of Saint Mungo bears similarities with Chrétien de Troyes's French romance Yvain, the Knight of the Lion . In Chrétien's story, Yvain, a version of Owain mab Urien, courts and marries Laudine, only to leave her for a period to go adventuring . This suggests that the works share a common source . </P> <P> On the spot where Mungo was buried now stands the cathedral dedicated in his honour . His shrine was a great centre of Christian pilgrimage until the Scottish Reformation . His remains are said to still rest in the crypt . A spring called "St. Mungo's Well" fell eastwards from the apse . </P>
