Book on GalileoEdit

In his 1983 book, Redondi developed a new approach to the trial of Galileo. According to this approach, the main reason for his conviction as "vehemently suspected of heresy" was not his advocacy of the Copernican worldview, but his earlier conflict with the Jesuits in his book Il Saggiatore of 1623, in which he advocated an atomist theory of Democritus that ran counter to Aristotelian doctrines endorsed by Rome as well as the Catholic doctrine of the Eucharist. A report to the Inquisition (sent anonymously in 1624, and first discovered by Redondi in the archives of the Inquisition) did not succeed at the time. The Jesuits saw a new opportunity in 1632 to start a trial of Galileo. Until then the pope and the Curia had patronized Galilei, but withdrew their support in 1632.

Redondi also dealt with the reception of Galileo and the idealization of Galileo in the 19th century. He also dealt with the Galilean researcher Alexandre Koyré.

From 1983 until 1993 he was founding editor of History and Technology. In 1985 he was awarded the Bronze Medal of the CNRS.
