The first pilasters grow from the arches of the lunettes, placing the pedestals in the middle, leaving, however, the greater part of the arch of the lunette--that is to say, the space they contain between them.

Above the said plinths are painted some little naked children in various poses, who, in guise of terminals, support a cornice, which binds the whole work together, leaving in the middle of the vault from end to end, as it were, the open sky.

This opening is divided into nine spaces; for from the cornices over the pilasters spring certain arches with cornices, which traverse the highest part of the vault, and join the cornice on the opposite side of the chapel, leaving from arch to arch nine openings, large and small.

In the smaller spaces are two fillets, painted like marble that cross the opening in such a way that in the middle rest the two parts and one of the bands, where medallions are placed, as shall be told in due course; and this has been done to avoid monotony, which is born of sameness.

Now, at the head of the chapel, in the first opening, which is one of the smaller ones, is seen how the Omnipotent God in the heavens by the movement of His arms divides light from darkness.
