Ezekiel's Divine Chariot

(Click on image for larger view.)
The Cathedral of St. Denis in Paris has a remarkable stained glass panel mixing a number of different Temple motifs. First, it represents Ezekiel's celestial chariot, with the four cherub/hayyot in the four corners. The central figure is the chariot with the four wheels. It is also, however, associated with the Ark of the Covenant (Latin: "arca foederis Domini"). Christ is represented as the figure on the divine chariot. Finally, the Green cross in the center of the image is a representation of the Cross as the living Tree of Life. Thus we have a symbolic conflation in the sanctuary of St. Denis's Cathedral of chariot, cherubs, ark of the covenant, cross and Tree of Life.
