Ephemerides Barometricae Mutinenses (anni M.DC.XCIV) Cum Disquisitione Causae ascensus ac descensus Mercurii in Torricelliana fistula iuxta diversum Aeris statum

This audio brings listeners into a 17th‑century scientific journal that tracks the behavior of mercury in a glass tube, the earliest barometer, over an entire year in Mutina. The author records daily rises and falls of the mercury column, noting how clear skies, cloud cover, and rain each influence the instrument. The narrative reads like a weather log, yet each entry is annotated with careful calculations and a restless curiosity about the invisible forces at work.

Beyond the raw data, the writer engages with the leading natural philosophers of his day, questioning the prevailing idea that heavier air simply pushes the mercury upward. He weaves personal dedications to patrons and lively exchanges with peers into the scientific discourse, revealing the collaborative spirit of early modern research. Listeners will hear a voice that balances scholarly rigor with the genuine wonder of watching the sky change day by day.
