“In Wolfram's telling, the Grail was kept safe at the castle of Munsalvaesche (mons salvationis), entrusted to Titurel, the first Grail King.”
The Younger Titurel (c. 1270-1272), attributed to Albrecht von Scharfenberg but long thought to be Wolfram's work, expands the genealogy and introduces explicit themes of longevity. Spanning over 6,300 stanzas in Middle High German, it describes how:
"God sent to Titurel, by now fifty years old and still remaining virginal, through an angel, the Grail, and showed him the way to Mont Salvat, on which the Grail temple was to be built... Titurel married at the age of four hundred years with Richaude of Spain." Sacred Texts ArchiveWikipedia
The Grail sustains life for extraordinary periods. Titurel's life exceeds 500 years, sustained by the Grail's presence. As Arthur Edward Waite's analysis notes: "It is understood that the successive kings and wardens lived to extraordinary ages, and in the case of Titurel the term of his life exceeded five hundred years. The Grail sustained him in his old age, and it was only when, having consigned his burden to Frimutel, he was removed from its immediate presence that he began to fail and died after a very brief period." catholiccultureSacred Texts Archive
The text explicitly states virginity as requirement for receiving the Grail: "Gott sendete Titurel, mittlerweile fünfzig Jahr alt und noch immer jungfräulich geblieben" (God sent Titurel... still remaining virginal). This requirement extends through the dynasty to Repanse de Schoye, connecting her purity to the Grail's life-preserving power.
Those in the Grail's presence cannot die; they do not age; their youth is preserved. The connection between virginity, purity, and the capacity to bear eternal life becomes explicit—the virgin vessel can contain and transmit immortality.
