In Rome's Barberini Palace there is a great painting by Guido Reni. It is a masterpiece showing the chariot of the sun coming through the clouds, horses and clouds, and darkness and light. The painting is very difficult to see because it is on a ceiling. The problem has been overcome by placing a long table with a mirror top underneath the painting. The mirror reflects exactly the painting on the ceiling. People gather around the table and look into the mirror to see the painting. Jesus is the mirror who perfectly reflects and reveals God the Father.
