1) BRUNO – Tenore ‘di grazia’ (leggero).

Giordano Bruno (Nola, Naples, 9 February 1548 – Rome, 17 February 1600).

Dominican friar, philosopher, mathematician, poet, and cosmological theorist, condemned for heresy by the Roman Inquisition, was burned at the stake in Rome’s Campo dei Fiori in 1600. Bruno’s human torch represents today, for a great number of intellectual Europeans, the beginning of the modern age and the symbol of the heroic love for knowledge.


2) DIANA – Soprano coloratura (luminous voice).

She symbolizes the Light that exists in the darkness of the matter, infinite nature, endless universe, shadow of the divine. (For Giordano Bruno God, in itself, is unknowable and ineffable - it is only cognisable  in his necessary reflection, the infinite nature –Diana).


3) CIRCE – Soprano drammatico (dark voice).

Sorceress and goddess of the magic. Symbol of the darkness, unknown and mysterious. She turns the humans into animals (into  pigs in Homero’s Odyssey), to show her maiden the beastly nature of the human being.

/ SOFIA: goddess of the wisdom, in the celestial Council (scene 6).


4) INQUISITOR I Baritono leggero.

He represents one of the domini-cannes –officials of the Holy Inquisition–, who pronounce the sentence against Giordano Bruno.

/MOMO: in Bruno’s Spaccio, he represents certain light of the conscience or "synderesis". God of the celestial Council (scene 6).


5) INQUISITOR II Basso–barítono.

He represents one of the domini-cannes –officials of the Holy Inquisition–, who pronounce the sentence against Giordano Bruno.

/GIOVE: (Jupiter) in Bruno’s Spaccio, he is the father of the gods and the father of men.

Principal god in the celestial Council (scene 6).


MIXED CHOIR (approx. 40 voices)

ISABEL I  (1+6=7 Sopranos of the choir)

Queen of England. In Bruno's work ' the unique nymph ', Diana's incarnation.


ENRIQUE III (1+4 = 5 tenors of the choir)

King of France, educated man who is interested in Bruno’s “arts of  memory”. De umbris idearum is dedicated to him.


RODOLFO II (1+2= 3 bass of the choir, 1º basso-baritono)

Emperor of the Roman-German Sacred Empire. An intellectual devotee of occult arts, alchemy and science, surrounded by experts and scientists from all over the world.


Teachers/tutors: 2 contraltos of the choir

They accompany the children and school youth  (scene 10)


CHILDREN and YOUTH CHOIR (approx. 20 voices)

2 young people 2 children (one little girl).

They symbolize the happiness (GIOIA) and love for knowledge, the hidden gardens and ardent volcanoes that we all have inside us. But at the end of the opera they also represent the idea of metempsychosis in the infinite worlds (one of the theses for which Bruno was condemned to die by burning at the stake).
