Hydrostaticae dissertationes

The Hydrostaticae dissertations is a subset of Paulo Casati’s most influential work, Terra machinis mota. Originally published in 1658 in Rome, this work is unique in that it imagines a dialogue between Galileo Galilei, Marin Mersenne, and Paul Guldin, three heavyweight physicists of the recent generation. Important for its detailed description of several experiments, such as one to determine the weight and dimensions of Earth, this work is also significant for its positive portrayal of Galileo a mere 25 years after his condemnation by the church. This is particularly momentous due to Casati’s devout Jesuit beliefs. Thus, the importance of this book lies in its historical and cultural value, in addition to its scientific contributions.
