Galileo, portrait of three astronomers, frontispiece from Systema Cosmicum, Augustae Treboc. [Strasbourg], 1635
In the first Latin edition of the Dialogo, the portrait has been reengraved and significantly altered from the Italian original. Two columns have been added, and above them the curtain with the dedication to Galileo's patron, the Grand Duke of Tuscany, is held not by Italian putti but by little angels, who also support the Medici crest. The astronomers' poses are similar to the original, but Copernicus looks out toward the reader and holds his model of the heliocentric system in a more prominent position. The names of the astronomers are engraved in the ground rather than on their garments. The arrow points more clearly to Copernicus. The small stones on the ground, much more than in the Italian version, appear to represent the the configuration of sun and planets.

Like the engraving of the three astronomers, the portrait of Galileo has been altered in the Latin edition of his Dialogo. He faces in the opposite direction and his titles are given in Latin. Additionally, some of the ornamental detail in the portrait has been altered to make the overall effect more sober. The engraving is signed Jac. al Heyden.
Galileo, title page from Systema Cosmicum, Augustae Treboc. [Strasbourg], 1635
The first Latin edition of Galileo's Dialogo (Dialogue on the Two Chief World Systems), prepared by the famous Dutch printer Elsevier but printed in Strasbourg. Not mentioned on the title page is the translater, Matthias Bernegger, who appended to the text an extract from Kepler's Astronomia Nova (published 1609) and a letter by Paolo Antonio Foscarini. The additions presented arguments to demonstrate that the Copernican system did not conflict with the Bible. The Decree of Condemnation under which Galileo stood in Italy had not been published in France, so his work could be printed there. This Latin edition was later brought out in Leiden and London.
