In Decoding the Stars, Ileana Chinnici offers an account of the life of the Jesuit scientist Angelo Secchi (1818-1878). As well as providing an invaluable account of Secchi's life and work-something that has been sorely lacking in the English-language scholarship-this biography will be especially stimulating for those interested in the evolution of astronomy as a discipline from the nineteenth century onward. 0Despite his eclecticism, reminiscent of the natural philosophers of the seventeenth and eighteenth centuries, Secchi was in many ways a very modern scientist: open to innovation and cooperation, and a promoter of popularization and citizen science.0Secchi also appears fully inserted in the cultural context of his time: he participated in philosophical and scientific debates, spread new theories and ideas, but also suffered the consequences of political events that marked those years and impacted on his life and activities.
