Filippo Salviati

On 5 September 1602 he married Ortensia, daughter of Francesco Guadagni and Laura Bandini;[7] their marriage was agreed and sponsored by the Grand Duke and Cardinal Medici.

[1] From the second half of 1606, Salviati began to immerse himself in study: for ten hours a day he kept himself away from other people and neglected his usual activities, buying many books.

He first perfected his knowledge of Greek and Latin through the reading of the classics, initially under the guidance of Giulio Libri, member of the Accademia della Crusca with the nickname 'Abburattato' ('Sifted'),[8] However he soon abandoned these Peripatetic teachings and embraced the views of Copernicus and the new natural philosophy.

[1] After a long period of disputes with his uncle he finally decided, in 1610, to withdraw from involvement in the family business in order to devote his time to natural philosophy.

[1] On 7 July 1610 Salviati himself became a member of the Accademia della Crusca (founded by his ancestor Lionardo Salviati)[5] with the nickname of 'Affidato' ('Trusted') His ceremonial membership spade bears the image of a Roman spearhead from which hangs a bundle of wheat with the motto "sotto 'l qual si trionfa" taken from a line in Petrarch's Canzone XLIX ('O solid shield for the oppressed peoples / against the blows of Death and Fortune / under whom we triumph').

In July 1611, Salviati's Florence residence in via del Palagio was chosen as the location for an experimental competition between Galileo and the Aristotelian Lodovico delle Colombe about the physics of floating bodies.

Niccolò Arrighetti delivered his funeral oration;[13] in Rome Federico Cesi paid him solemn tributes and commissioned his biography from it:Josse De Rycke, who composed only a poem and a cenotaph.

[1] Many years after his friend's death Galileo recreated him as a character in his controversial Dialogue Concerning the Two Chief World Systems (1632) and in the later Discourses and Mathematical Demonstrations Relating to Two New Sciences (1638).

In these works the character of Salviati is an expert Copernican mathematician, whom Galileo uses to argue controversial or potentially heretical views, and ultimately win the argument.
