A rod, in this Perugino’s fresco, is accompanied by white doves, a serpent and a carriage. But, moreover, is held by its very synonym: Moon-Diana.

pietro perugino collegio cambio luna dianaThis painting is part of a monumental cycle of frescoes inside Collegio del Cambio, in Perugia, Perugino’s home-town (1). Painted from 1496 to 1500, it is known as Perugino’s masterpiece, and probably he had the feeling, since he placed his auto-portrait, accompanied by a self-satisfied latin inscription, facing his triumph in the opposite pillar.

The “volta della Sala delle Udienze”, or audience hall’s vault is covered by the seven planets represented by the seven major classical deities. Apollo, as the Sun, is in the centre. In fact, commonly, this painted vault is taken as an example of Universe representation. Nevertheless one can be puzzled by the main topic of the fresco on the walls: a virtues representation, that’s to say the four cardinal ones – Prudence, Justice, Strength and Temperance – and the theological three – Faith, Hope and Charity. Most modern art critics run over this strange blend, saying being a merging of classical and catholic knowledge.

audience hall palazzo cambio perugiaAlmost all agree in stating these Perugino’s frescoes are the italian humanistic painting masterpiece, only surpassed by Raffaello Sanzio’s, who was a Perugino’s pupil, Vatican Rooms. They are right, nevertheless they fail to understand the real essence of humanism, since the revived interest in ancient Greek and Roman thought wasn’t detached from supernatural matters. In fact Planets and Virtues could not be in connection, but through a hermetic line of thinking.

In fact, why to give a rod to the Moon, if she is not our Moon? We have already mentioned rod symbolism and see how this sign may take origin from the biblical Moses episode of the water springing out of a rock (2). And how salts volatilization, during distillation or sublimation, is involved (3). But in Perugino’s Moon representation we exactly know when the first rod does start: from the preliminary works.

The Moon, in Alchemy, stands for several meanings. Of course, the rule of three gives her many possibilities (4), here she represents our basic salts volatilization and the transformation from raw matter to our Secret Fire/Mercurius. Our Water, even if not in liquid state.

The Moon, our Moon, is not separated from the other planets-deities in this art work. In fact each of them stand for a given operation. The Moon is the first and the Sun-Apollo is the final goal, the successful end of our alchemical works. Most important: all the planets and deities here represented are nothing more and nothing less that our initial Moon/Mercurius transmutated to our final Sun/Perfect Red, through all the others. That’s the meaning of the carriages they are all travelling on.

We see the evidence of a Moon representation just by the latin “Luna” inscription under the lunar scythe and the sign of astrological cancer on the carriage wheel. But the white woman, so immodestly painted nude, is unquestionably Diana, Apollo’s sister.

Diana is in the mainstream of hunting female deities, like Atalanta (5). Hunters are looking for victims to dissolve, their bows represent our Universal Dissolvent.

The two serpents brought along by Diana’s servants are a representation of caduceus, which we will talk about when talking of Asclepius. For the moment note the typical flowing movements of serpents: that of watery substances.

The doves stand for this “whiteness” suddenly appearing on the surface of the black mass, as though it has landed from the sky.

Finally, the rod, which might look like an arrow just for the presence of the bow on the other hand of the Goddess, but it is not. It is a rod, indeed, as well as a scene summarize. It is Diana, our dissolving hunter. As solemnly declared by the griffins ( other symbols of Mercurius) around the frame.
