The Mural tradition of Kerala Churches
The mural paintings remained a major medium of public communication for over a thousand years. Great cycles of religious stories were spread across the walls of ecclesiastical structures almost as Christianity became state religion in west and at a similar period in east. Pope Gregory the Great ( 590-604) is said to have encouraged the pictographic forms as the ideas conveyed are universally communicable. For a long time in history pictures, inscriptions worked together as an explanatory symbiosis of Christianity.
