From the beginning of Galileo's career, well before the publication of the <i>Sidereus Nuncius</i>, his contemporaries took pains to shape his reputation and fame. They were fully aware that their efforts would shape the course of his career; they also knew that they would profit from helping him. With this book, Anna-Luna Post offers a welcome new perspective on the volatile dynamic between early modern fame and science in Italy, shifting the focus from the recipient of fame to its brokers. Galileo's contemporaries knew his rise to fame was not a matter of course. Not only were his discoveries highly contested, he was also not the first to observe Jupiter's four largest moons. Yet, of the three men who did so between the summer of 1609 and the winter of 1610, Galileo is the only one who achieved both widespread fame and posthumous glory. Rather than the direct result of merit or extraordinary achievements, fame, Post reveals, is shaped through human intervention.
