Bruno on the Moon

Back side of the moon

The bright region at the upper left is the crater called Giordano Bruno.
It's positioned at the border of  the visible satellite's face .
As well as  Bruno's thought,  always trying to cross the limits of unknowable.

 The impact that formed the 20-kilometer-diameter crater was observed by five men on the evening of June 18, 1178, and was reported in medieval chronicles. No other similar events on the Earth or Moon have been observed during recorded history (Hartung, 1976).

Bruno has already been on the Moon. Cyrano de Bergerac has lead him there  in 1648,
 in  "L'autre monde ou les états et empires de la Lune".
Jean Rocchi in his work  Giordano Bruno après le bûcher   (page 221) acutely points out:
"Dyrcona (Cyrano's anagram) meet a character disguised as a demon of immortal Socrates, that a sagacious reader would recognize without too much effort.. Cyrano says to us that this man arrived on the Moon, he does not have there a long time, after having gone on a journey in Europe, where he meet Doctor Faust, Knights of the Rosicrucian brotherhood and Campanella, while he was before the Inquisition in Rome. He was born in the Sun. He remains on the Moon because:  one does not see pedants there, the philosophers are persuaded only with the reason, and either the authority of an erudite, or the greatest number, do not prevail over the opinion of a thrasher, if the thrasher has strong reasons.
A new mirror's play: this demon of Socrates met in England, where he studied manners of its inhabitants, a man of which he says the name, but which could extremely well be himself, according to description that he makes; this man is the shame of his country, because it's a shame for the great men of your State, to recognize the virtues that he personifies, without they adore him. He is all spirit, he is all heart. He is the only poete, the only philosopher and the only free man that you have.
Who is this attractive character? Cyrano will not say any more, but he will add an ultimate allusion when, after having left him, Dyrcona, returning towards the Earth, falls on a mountain all on fire until he lies on heathers at the top of a small hill, in Italy. This demon of Socrates, Italian, great traveller was son of the Sun, the Vesuvius and the hill of Cicala. He had a name that Cyrano could not pronounce.
