The Holy Grail
We see the symbology of the Eucharist when the sun, as personified by Jesus, crosses the Fall Equinox. As the sun sets lower and lower in the horizon, sunsets get more and more red. The red symbolizes bleeding; with the last bloodletting on the Winter Solstice, December 21. In the image below, when the sun is in Virgo, her sheaf of wheat represents bread. The Holy Grail as Crater catches the falling blood.
26Now as they were eating, Jesus took bread, and blessed, and broke it, and gave it to the disciples and said, "Take, eat; this is my body."
27And he took a cup, and when he had given thanks he gave it to them, saying, "Drink of it, all of you;
28for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.
29I tell you I shall not drink again of this fruit of the vine until that day when I drink it new with you in my Father's kingdom." (Matt. 26:26; Mark 14:22-26; Luke 11:23-25; John 6:53-58; 1 Cor. 11:23-26)
51I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh." (John 6:51)
