Chamber of the giants

In a curious but coherent way, the sky ends behind Jupiter's canopy just as a vault would. The heavens are closed, in a manner that is characteristic of Giulio Romano 's art, that combines an invented reality with an artificial space. The twelve columns, almost hidden by a cloud, support the imaginary part of the cupola and trace another circle, a third one with respect to the one formed by the clouds and the one created by the canopy. The result is a celestial chart, that the Giants intend to destroy.
