Before coming to Harvard, she worked as a postdoctoral researcher on the Galileo Correspondence Project, which she directs with Paula Findlen. Marcus has three book projects underway. The first, *Forbidden Knowledge: Medicine, Science, and Censorship in Early Modern Italy*, explores the censorship of medical books from their proliferation in print through the prohibitions placed on many of these texts during the Counter-Reformation. This account explains how and why the books prohibited by the Catholic Church in Italy ended up back on the shelves of private and public Italian libraries in the seventeenth century. Her second book, *Methuselah’s Children: The Limits of Life in Early Modern Europe,* is a study of ideas about longevity and experiences of advanced old age in a period when the average life expectancy was 35. With Paula Findlen, she is also engaged in a study of Galileo’s correspondence called *Galileo’s Letters: Experiments in Friendship*, which grows out of their collaboration on The Galileo Correspondence Project. Marcus teaches courses on the changes in scientific ideas and practice between the medieval and early modern periods, especially focusing on the early history of science, medicine, and the body, communication technologies, and the relationship between faith and science. - ## People: Department Search [History of Science](/people-department-search/history-science) - ## People: Filtered Search [Faculty](/people-filtered-search/faculty) - ## People: Theme Search [History of Science](/people-theme-search/history-science) [Intellectual History](/people-focus-search/intellectual-history) - ## People: Region Search [Europe](/people-region-search/europe) [Italy](/people-region-search/italy) - ## People: Time Period Search [15th Century](/people-time-period-search/15th-century) [16th Century](/people-time-period-search/16th-century) [17th Century](/people-time-period-search/17th-century)
