Peridexion Tree
The Peridexion Tree, (also known as the "perindens") is a mythical tree which grows in India. Doves live in this tree, and feed on the sweet and pleasant fruit which the tree produces. Dragons, which are the enemy of doves, fear the shadow of the tree, and so the doves nest in the shade of the tree. While they remain in the tree, they are safe, but if any leave the tree, they are caught by the dragon and killed.
The story of the Peridexion Tree is allegorical of the christian faith. The tree is God the Father, the shadow of the tree is God the Son, and the fruit of the tree is the wisdom of the Lord, that is the Holy Ghost. The doves are christians, who are safe as long as they remain faithful to the church, but if they leave the church, they will be caught and devoured by the dragon , who is the devil.
