Giovanni Tuccari, the painter who frescoed the church vault, was named “fulmine della pittura” (lightning-fast painter) for his speed. It took him very little time to paint such a large surface, because he used the same technique as some 18th-century artists who had similar requirements.
From a distance of little less than twenty metres, the drawings seem very elaborate, but they are in fact large brush strokes placed side by side in order to create optical effects.
Sometimes the colours are more blurred, sometimes they end more abruptly.
