PostMore on the Valencian Holy Grail (Consoly Leon Arias, Spain / Canary, 01/25/22 3:51 am)
To answer John E's question, it may be surprising or even incredible, but the truth is that until 2019, no one had carried out a rigorous and focused study on the Chalice in the Valencia Cathedral. Hence, there was no absolute certainty that the Holy Grail is the one located in Spain.
JE comments: I should read the Mafé book for the details, but it is surprising that no one thought to undertake a study prior to this Millennium. It seems that Franco in particular would have relished the prestige of having the Grail in his custody. Might Valencia's distinction as a Republican city have lessened his enthusiasm?
