Mariotta is a French physician from Florence. Doctor of Medicine. For ten years after accepting French citizenship, he conducted some medical studies and many statistical studies in the field of medicine in Paris, some of which are contained in the essay: “Vie du roi Louis XIII”. The most famous work is the book "De Morbis Commerciautium lectio". Marion described the laws of falling bodies in the book: “Novum lumen de motu corporum”, published in 1675 at the French Academy of Basel. In addition, Marion left a book about what he himself called “The Art of Medicine.”
Marion believed that all diseases should be treated only with medicine, and the effectiveness of any medicine is quite high. This prompted him to discover the “Apothecary Law” (“Law of Falling Bodies”): heavy objects fall more strongly than light ones, especially if they are tied with a thin end to the stretched end of a thread.
