The Last Supper is the second most famous painting that Leonardo Da Vinci painted after the Mona Lisa. The Last Supper is actually a mural painting that is found on the walls of the dining hall at Santa Maria delle Grazie, a church found in the Milan region of Italy. The painting is huge in size measuring 4.6 metres by 8.8 metres. The Last Supper became a prominent figure in the Holy Grail myth with the publishing of the best selling novel the “Da Vinci Code” by Dan Brown. In the story by Dan Brown, Leonardo Da Vinci is said to have been a Grand Master in the Priory of Sion who protect the secret that Jesus was married to Mary Magdalene and they bore a daughter named Sarah so there are people of Jesus family lineage alive today. Further more the novel went on to say that Leonardo hid coded messages of the Priory of Sion and the Holy Grail within the Last Supper painting. While we cannot actually say this is true I will show you the coded messages that many people refer to when looking at his mural.
