What does the circular halo placed behind the head signify in the art of the Middle AgesA. Divinity. B. Sainthood. C. God. D. Sky.
A second characteristic of this iconography is obedience to a sacred mathematics. "The Divine Wisdom," wrote Saint Augustine, "reveals itself everywhere in numbers", a doctrine attributable to the neo-Platonists who revived the genius of Pythagoras. Twelve is the master number of the Church and is the product of three, the number of the Trinity, and four, the number of material elements. The number seven, the most mysterious of all numbers, is the sum of four and three. There are the seven ages of man, seven virtues, seven planets. In the final analysis, the seven-tone scale of Gregorian music is the sensible embodiment of the order of the universe. Numbers require also a symmetry. At Charters, a stained glass window show the four prophets, Isaac, Ezekiel, Daniel, and Jeremiah, carrying on their shoulders the four evangelists, Matthew, Mark, Luke and John.A third characteristic of art is to be a symbolic language, showing us one thing and inviting us to see an other. In this respect, the artist was called upon to imitate God, who had hidden a profound meaning behind the literal and wished nature itself to be a moral lesson to man. Thus, every painting is an allegory. In a scene of the final judgment, we can see the foolish virgins at the left hand of Jesus and the wise at his right, and we understand that this symbolizes those who are lost and those who are saved. Even seemingly insignificant details carry hidden meaning: The lion in a stained glass window is the figure of the Resurrection.
These, then, are the defining characteristics of art of the Middle Ages, a system within which even the most mediocre talent was elevated by the genius of the centuries. The artists of the early Renaissance broke with traditional at their own peril. When they are not outstanding, they are scarcely able to avoid insignificance and banality in their religious works, and, even when they are great, they are no more than the equals of the old masters who passively followed the sacred rules.
