Below the description of it.

This ceiling is 64 feet long, out of 4 wide, and eight and a half feet of indentation area from corniche to top.

The Figures in the attica have ten to eleven feet of proportion;

One can count in the entire Work up to 142 Figures, included about thirty, feigned stuccos.

One can see 62 at a glance by discovering the main Group.

The whole Work rolls on this thought:

The Love of Virtue elevates man above himself and makes him superior to the most difficult and perilous work; the obstacles vanish in the view of the interests of his King and his Fatherland, supported by honour and driven by loyalty, he reaches by his actions to immortality.

The Apotheosis of Hercules appears well suited to develop this thought: This Hero was busy during his life only to immortalize himself through virtuous and heroic actions;

and Jupiter of which he had been the image on earth, crown his work in Heaven by immortality.

This is the general idea of the subject.

Hercules presented to Jupiter by the Love of Virtue, is pulled in a Chariot by the Geniuses of the same Love.

Monsters and Vices tamed by the value of this Hero, cannot support his glory are overthrown and rush by making unnecessary efforts to bring it to bear.

Jupiter introduces him to Hebe, Goddess of Youth, led by the Hymen.

On the opposite side is Apollo, which invites the nine Sisters to celebrate the high feats, and the Apotheosis of the new God.

Behind Apollo is the Temple of Memory.

Above the Corniche, reigns around an Attica that encircles the Subject, it is drawn up in the middle of enhanced Golden Cartels, accompanied by the main works of Hercules feigned of Sculpture of white marble.

In the corners of the Attica, are four Virtues on Pedestals and feigned the same way.

These Virtues are Force, Your Constancy, Value, Justice, which specifically refers to the character of Hercules.

For the rest, the composition is distributed in nine Groups.

In the first, under a Curtain supported by the Satellites of Jupiter, this God on a throne is intend him for spouse;

Juno who crossed Hercules during her life, seems to approve this change, ingenious figure that proves that the Virtue always overcomes Jealousy and Envy.

at the feet of Jupiter, one sees the Eagle repository of lightning;

Ganymede is next to Hebe, looks with pleasure at the happiness of this Goddess.
