Note 30 — Chapter VI · The Grateful Dead and The Water of Life or Kindred Themes.
Reading edition
It is worth our while to note in this connection that all these nine variants come from southern Europe, directly or by derivation.30 Geographical proximity, though not sufficient in itself as a basis of classification, adds welcome confirmation to other proof in cases like this, where a small group of highly complicated tales is found to exist in neighbouring countries only. That Walewein can be connected with this specialized sub-division has important bearings on the question whence the material for that romance was taken. In view of the limited territory which this form of the story has covered as a folk-tale in six hundred years, and the fact that France would be the centre of the region, it seems fair to assume that some thirteenth century French writer took a märchen of his own land as the basis for his work, thus elaborating with native material the adventures of a Celtic hero.
