The transfiguration has been defined as “the feast of iconographers” because of its peculiar importance: once, every iconographer began his “divine art” with this solemn scene.

This living and direct initiation taught mainly that the icon is painted not as much as with colors but also with the light of Mount Thabor. It is the mother of all icons, in the sense that every icon has to reflect itself in the same light that shone on Mount Thabor.
