Career
Jaszlinszky joined the Jesuits (October 1733 in Trencin) and published his physics textbooks as a professor at the University of Trnava (Kingdom of Hungary in modern-day Slovakia), where he taught philosophy, metaphysics, history, ethics, physics and theology. Publication of Physica Generalis and Physica Particularis occurred in response to a 1753 order from Maria Theresa (Habsburg ruler in Vienna) requiring every professor to write textbooks instead of dictating lecture notes, which created a surge of works by Adanyi, Jaszlinszky, Reviczky, Radics, and Horvath. He was a contemporary of Johann Baptiste Horvath, Leopold Biwald, and Joseph Redlhamer.
These Latin physics textbooks each contain eight plates with descriptions and images of a variety of contemporary physics devices including manometers (fluid statics), lenses/prisms (refraction), and various simple machines.
Coverage of electricity is relatively sparse, although many other diverse topics are surveyed, including mechanics, magnetism, celestial mechanics, fluid drag experiments, mineralogy, and human anatomy. Extensive bibliographical references are provided.
Interestingly, these textbooks (1750s) at least somewhat ambiguously reflect incorrect Cartesian vortex mechanics, rather than the correct Newtonian mechanics fully embraced by Horvath (1770s). Indeed, modern Newtonian mechanics (1687) was only widely accepted in Hungary by the 1760s and 1770s.
Indeed, Jaszlinszky essentially rejected the Ptolemaic approach.
Jaszlinszky was also the author of Tractatus Theologicus de Angelis, Beatitudine et Actibus Humanis (Trnava, 1762/1769, 574 pp) and possibly Geographica (1761), in addition to Institutiones logicae (Trnava, 1754, 164 pp) and Institutiones metaphysicae (Trnava, 1755, 288 pp), consistent with how the Ratio Studiorum (1599) was applied following Christopher Clavius. A copy of Physica Generalis is provided by Google Books. Images of the textbook title pages are also available.
Each of these textbooks is worth approximately $150 depending on condition.
The plates shown below are from a copy owned by multiple professors at the Collegio Romano around 1762.
