Look, the issue never was where Plantard's inspiration for choosing Dagobert II was from. This is not an article on Plantard or his hoax. The only reason to mention Plantard at all here is connections between him and the topic of this article. I don't know if Plantard mentioned the Grail or not (Richardson does not imply that he does, however), but Evola sure did, and according to Richardson Evola influenced Plantard, who in turn influenced the Holy Blood, Holy Grail guys (who obviously mention the Grail.) t/c
