Borelli, Giovanni Alfonso

1. Dates
Born: Naples, 28 Jan. 1608 (Borelli deliberately obscured his date and place of birth, apparently to conceal his connection to his father's political difficulties, and possibly his own connections with Campanella. Baldini cites his baptismal record, however, and it appears decisive.)
Died: Rome, 31 Dec. 1679
Dateinfo: Dates Certain
Lifespan: 71
2. Father
Occupation: A Spanish Soldier In The Garrison In Naples
There is every reason to think the family was poor.
3. Nationality
Birth: Italy
Career: Italy
Death: Italy
4. Education
Schooling: Naples, M.D.
It is possible that he was taught by Tommaso Campanella, while the latter was a prisoner at the Castel Nuovo, Naples, where Borelli's father was stationed.
It is also possible that he received medical training at the University of Naples, but no records of his attendance or any degree exist. Baldini thinks this is not just possible but probable, and I am accepting his argument.
After 1628, he became a student of Castelli in Rome, at the same time as Torricelli.
5. Religion
Affiliation: Catholic
6. Scientific Disciplines
Primary: Mathematics, Physiology, Astronomy
Subordinate: Mechanics, Medicine, Geology
Borrelli was basically a mathematician during the first two decades of his career. In 1658, he published Eculidus restitutus.
In 1649, he published a work on malignant fevers.
He carried out an important investigation of volcanoes.
Borelli, who ranged very widely could also be listed under anatomy (in Pisa, he carried out extensive anatomical dissections), natural philosophy (he was an important figure in the development of the corpuscular or mechanical philosophy), hydraulics, and meteorology.
7. Means of Support
Primary: Academic Position, Patronage
Secondary: Schoolmaster
1637, Public Lectureship in Mathematics at Messina.
1642, Senate of Messina, (perhaps encouraged by Castelli) made him a member of the city nobility and provided him with ample funds and sent him on a tour to hire teachers away from leading universities. During this period he became friendly with the family of the Rao-Requesens, one of the most important families in Sicily; he was especially close to Simone R-R.
1643-56, remained at Messina. Poggendorff [ref. Z7404.P72 v.1, 239] indicates a professorship from 1649.
1656-67, Professor of mathematics at Pisa. He was there at the behest of the Medici.
1667-72, returned to Messina, and resumed chair.
Borelli fled Sicily for political reasons. In Rome he became the physician of Queen Christian of Sweden, who supported him as far as her means allowed.
1677-9, taught mathematics at the Scuole Pie, Rome.
8. Patronage
Types: Court, City Magistrates, Aristocracy
Primarily supported through many years by the Senate of Messina.
After fleeing political turmoil in Messina for Rome, in 1672, and needing support, he petitioned Cassini, a member of the Académie, for royal support. Negotiations were underway for dedication of De motu animalium, in 1677, when all of Borelli's belongings were stolen.
1679, he eventually dedicated De motu animalium to Queen Christina, who had agreed to pay the printing costs, see also below.
The Medici brought Borelli to Pisa.
He dedicated his work on the Natural Motion of Heavy Bodies to the Marchese di Arena, Secretary of the Accad. degli Investiganti (Naples)
He dedicated De vi percussionis to Giacopo Ruffo, Viscount of Francavilla, his pupil and friend both in Pisa and Messina.
Queen Christina guaranteed the publication of De motu animalium.
9. Technological Involvement
Types: Medical Practice, Instruments, Hydraulics, Cartography
1647-8, at the urging of the senate of Messina, he studied the epidemic fevers raging through the population, and devised a treatment, though it does not seem to have been widely applied.
1665, established an observatory at the fortress of San Miniato with some instruments of his own design.
While in Florence, he edited books on hydraulics and worked for the Grand Duke on lagoons near Pisa.
Borelli proposed a method of determining longitudes with a clock.
10. Scientific Societies
Memberships: Accademia del Cimento, Accademia degli Investiganti (Naples)
A member of Messina's Accademia della Fucina (date not certain); the Accademia del Cimento, Tuscany (ca. 1656-6); the Accademia degli Investiganti, Naples; and a founding member of the Accademia dell'Esperienza or Accademia Fisica- matematica (1677) which Queen Christina supported.
