Holy Grail or Royal Blood
The best known version is that the Holy Grail is the cup that Jesus Christ used during "the last supper". It is believed that when Jesus was resurrected, he gave it to Joseph of Arimathea and told him to take it to the Isle of Britain. Joseph would collect, with the chalice, the blood and water from the wound opened by the spear of the centurion on the side of Jesus Christ and then, already in Britain, established a mystical dynasty of guardians to keep the Holy Grail safe and hidden. But the mystery of the Holy Grail holds many secrets ...
The eternal search for the Holy Grail, through the ages, has led us to many theories and legends; one of them is closely related to the Knights Templar and the story of King Arthur, which combines the Celtic tradition with the Christian. Myths have multiplied over the years and, in our modern era, other assumptions have been established, some of them without much sustenance, such as the one reinforced by Dan Brown (and other writers) in his novel "The Da Vinci Code" , where it is assured that the Holy Grail was not a cup, but Mary Magdalene (who was the receptacle of the divine seed, having a relationship with Jesus, that would help maintain a lineage) ... Brown is based on clues that Da Vinci supposedly left in his paintings as a secret code, since the Renaissance artist supposedly knew about this theory.
This explanation is also based on some ancient texts that refer to the Holy Chalice as San Gréal (Royal Blood) and that under a different interpretation, almost esoteric, refers again to the descendants of Jesus, rather than the collection of his blood. Obviously the medievalists and the church have gone against this belief, which becomes somewhat fanciful, especially because in our collective mind is deeply rooted the idea that the Holy Grail is and always has been, the divine cup that Christ used with the apostles.
And returning to this last and "official" belief (so to speak), the great mystery lies, assuming that said Chalice was the Holy Grail, in the place where it has been hidden and where it is now.
While some say that the true Holy Grail is a golden cup, others have said it was (is) made of wood. The first author to mention the Grail was the poet Chrétien de Troyes in 1181 with his narrative "Perceval", which has direct reference to the medieval legend of King Arthur; With a Christian symbolism, some scholars emphasize that the author never explained in the work what the Holy Grail was, in addition to the fact that the work is abruptly interrupted.
It was Robert de Boron and Wolfram Von Eschenbach who would develop the history and meaning of the object (including Joseph of Arimathea, who supposedly hid the Chalice in Britain) in the way that medieval Europe knew it.
