The frescoes and the cathedral's majestic interior are perceived by the viewer as an integral whole. They are a veritable suite in colour combining golden, blue, emerald green, pink and white shades in perfect harmony. They are remarcable for he expressive quality if their individial compositions and their almost melodically flowing lines. The masters who decorated the cathedral made an inscription on one of its walls which testifies to their appreciation of art's lofty goals. Its concluding words say : "We have wrought this isographic creation for the spiritual enjoyment of all people for all time."
