We are creating a ‘galaxy’ of books – each one inspired by a different planet. With that metaphor in mind – special printing techniques have been applied to the cover of each book to reflect the planet they represent and create an experience for the reader, as they discover the title of each book.


Dialogo sopra i due massimi sistemi del mondo

Published in 1632 and written in the form of a dialogue between several characters in Italian, the author attacks the geocentric model of Ptolemy’s solar system and defends the Copernican heliocentric model.

Galileo was accused and judged by the church for holding the belief, considered heretical, that the Earth moves around the Sun. The Inquisition prohibited the works that affirmed the centrality of the Sun and the mobility of the Earth, the Copernicus’ De Revolutionibus was also prohibited, and they prohibited Galileo from teaching or defending, nor how to hypothesis or as truth, the Copernican doctrine.

The dialogue takes place in Venice during 4 days, where three interlocutors discuss the ptolemeic system and the copernican. The book is not neutral, but clearly defends heliocentrism, with different arguments.

The three characters are:

  • Filippo Salviati: he is a copernican, refers to a Florentine nobleman who met Galileo in 1611.
  • Gianfrancesco Sagredo: he is a neutral personage, but in fact he is let convince by Salviati. He is the friend of the soul of Galileo, known from his time in Venice. Is the host of the meeting.
  • Simplicius: represents ptolemaic thinking.

We linked Dialogo to Jupiter. Jupiter is a very gaseous planet. To connote this idea, the title is hidden behind a translucent sheath that lets the reader take a glimpse into the title.
