Leonardo da Vinci completed his famous painting of the Last Supper in 1498. Soon thereafter, the paint began to peel and disintegrate, perhaps due to moisture in the monastery's refectory, although Javier Sierra, author of The Secret Supper, asserts that Leonardo intended for the painting to "self destruct" to punish the Dominican monks who commissioned it for their role in obliterating the Cathars through the "Holy Office of the Inquisition."
"The Last Supper" contains many anomalies, including a hovering grail on the far left side of the painting, discovered by the team of art experts who restored the painting between 1979-1999, clearly visible in photos of the painting made since its restoration.
The team of artists who restored the Last Supper mural of Leonardo on the walls of the Maria del Grazie monastery in Milan discovered the "Grail" in the painting (hovering over the head of St. Bartholomew, the Apostle pictured on the far left of the painting).
Apparently in the late Middle Ages many painters included a gratuitous knot--the "knot of Isis--in their paintings. According to Javier Sierra in "The Secret Supper" (his mystery novel about Leonardo's painting), a gratuitous knot (like the one in lower right corner of the tablecloth in the painting) symbolized that the painting was dedicated to Mary Magdalene and the "secret tradition" (the full humanity of Jesus, ascended on a spiritual plane).
A line drawn from the chalice ("grail") floating above the head of the apostle on the far left and into the knot in the tablecloth passes directly under the chin of the "Beloved Disciple" (Mary Magdalene?) where Peter's hand is cutting across her throat chakra in a threatening gesture, and also through the left hand of Jesus (symbol of the Feminine). There's NO chance that this was a mere accident! The measurement between the cup of the chalice and the chin of the "Beloved" is the same as the distance from her chin to the left hand of Jesus, while the distance from Jesus' hand to the knot in the tablecloth is double that measurement. By placing these symbolic elements in direct relationship with one another (rations of 1:1:2), Leonardo was apparently saying that these elements--the Grail, the silencing of Mary Magdalene, the "left hand" of Jesus and the knot of Isis representing the secret tradition--are integrally connected.
The ratio is the beginning of the famed "Fibonacci sequence"--symbolic of life.
The very feminine figure of the "Beloved Disciple" has her hands folded in the classic position of the "prayer of the heart" (fingers crossed in little X's)-- the original hand position for the idiomatic expression, "I'll cross my fingers for you." This hand position is very familiar in artworks depicting Mary Magdalene (See: George de la Tour's "Penitent Magdalene with the Twin Flames." El Greco's "Penitent Magdalene," "Marie Madeleine" at the altar at her church in Rennes le Chateau, to name three.
