Iatromathematics, also known as iatromechanics or iatrophysics, is above all a designation applied to a school of thought or to a sect of physicians. It claims to be able to subject all living phenomena to the rigors of computation, explaining all laws of physiology in terms of mechanical forces and by expressing all capacities through mathematical formulas.
The initiatory events that promoted the emergence of the iatromathematical animalimu can be reduced to just a few main factors. As iatromechanics was seen in a favorable light by the luminaries of the day, from the end of the seventeenth century, it progressively succeeded iatrochemistry over the course of a century.
It was particularly through the investigations by Santorio Santoriowho had tried to accurately measure body temperature and pulse, that the application of measurements and brelli to functioning of the body gained momentum. Documentation of the process of blood flow, as conceived by William Harveyboosted this way of thinking, thus equating the vascular system to a hydraulic machine for which the driving force or the quantity of propelled and circulating fluid can be calculated.
He explained physiological phenomena of the body notu referring to the structure and the movement of atoms.
Physiology became a part of mathematics since the laws governing the movement of these atoms could be determined and calculated just like the movements of any other machine.
In Italy science and the liberty to think were given free reign. As the cradle of natural history, it was there that science was molded to comply with the rigorous laws of mathematics. Scientists could only oppose scholastic borrlli by arming themselves with experimental physics, for which Galileo Galilei deserves particular acknowledgement.
Through the genius of his great discoveries in physics, mechanics, astronomy, architecture, and other sciences, he inspired many Italian scholars to fully embrace the study of natural sciences and experimental physics.
De motu animalium …
Giovanni Alfonso Borelli, the leader of the iatromathematics discipline, trained in this academy for about ten years, where he was taught how to unite mathematics and experimental physics with the art of healing.
Along with doctor and naturalist Marcello Malpighithe two dissected numerous animals in order to understand anatomy. The young Borelli, born in Naples on January 28,was under the tutelage of the Dominican monk Tommaso Campanella and then Benedetto Castellia disciple of Galileo, in Pisa.
Yet the most original contributions of this mathematician consist of the implementation of mathematical theories and the laws of statistics regarding the constitution and functioning of living organisms and the application of hydraulics in physiology, particularly for understanding locomotion. Before Borelli, scientists had barely examined the mechanics of muscular movement. Those who had tried to study it were engrossed in writing primarily about superfluous aspects.
It was published postmortem inperhaps out of fear of the views of the reigning religious inquisitor.
Indeed, at that time, the Catholic Church oversaw cultural and ideological life, as well determining what written materials were sanctioned for wider distribution. Anijalium book summarizes all the knowledge accumulated during his productive career. A career that was dedicated to teaching applied mathematics in the foremost Italian universities to promote understanding of, amongst many things, movements of living creatures, and indirectly a better understanding of life.

In this book he developed these iatromathematic concepts. It is composed of two parts: The first volume consists of 23 chapters and proposals and focuses on the mechanical action of muscles as they act on the movement of bone segments, generating locomotion such as walking, running, jumping, flying, and also swimming.
He shows that the mechanics of bone movement are akin to a annimalium of levers e. He also refers to the notion that the very oblique insertion mode of these powers, such as being closer to the center of movement than to the resistance, results in an enormous loss of strength.
The second part analyzes the laws governing the functioning of major physiological systems.

Divided into 22 chapters and proposals, it focuses essentially on the physiology of the heart, lungs, and other organs. Borelli calculated cardiac output and mtou the contraction of the cardiac muscle in detail. He developed specific measuring instruments—a spirometer in particular—to determine the various volumes of the thoracic cavity. He noted that blood circulation is linked to the dimensions of the cross-sectional area of blood vessels.
Despite the lack of accuracy of the calculations, the first part of the work on the movement of animals represents an epistemological stage in the history of sciences of biomechanics, as well as for medicine. It is true that Borelli developed his mechanical explanations for all functions of the body to a point of excess, and the evaluations that he made in regard to the strength of various organs rests entirely on obrelli assumptions.
Yet these ideas contributed to more daring opinions being corrected, to the deduction of proposals, and to the development of less erroneous theories. By adhering to the views of iatromechanics, Borelli, who was a strong supporter animaliim the rigor of mathematical demonstrations, wished to achieve a rational understanding of the nature of humans, the mechanisms of life, of disease, and of death.
For this method alone, his approach has merit as it provided a precedent, generating interest and encouraging critical assessment for the centuries that would follow him, while also participating indirectly in the development of biomechanics, physiology, as well as medicine.
