These documents paint an incomparable firsthand picture of Galileo This unique critical edition presents key early biographical accounts of the life and work of Galileo Galilei (1564–1642), written by his close contemporaries. Collected and translated into English for the first time and supplemented by an introduction and incisive annotations by Stefano Gattei, these documents paint an incomparable firsthand picture of Galileo and offer rare insights into the construction of his public image and the complex intertwining of science, religion, and politics in 17th-century Italy, says a review on the Princeton University Press website. Here in its entirety is Vincenzo Viviani’s Historical Account, an extensive and influential biography of Galileo written in 1654 by his last and most devoted pupil. Viviani’s text is accompanied by his “Letter to Prince Leopoldo de’ Medici on the Application of Pendulum to Clocks” (1659), his 1674 description of Galileo’s later works, and the long inscriptions on the façade of Viviani’s Florentine palace (1702). The collection also includes a Latin poem written in 1620 by Cardinal Maffeo Barberini.
