Back at the parish, Diviš became responsible for the management of farmland belonging to it. He undertook the construction of water conduits on the property. As a result, he became interested in a popular new interest of the scientific community of his day: "electricity."

The news of the death of [[Georg Wilhelm Richmann]], a professor in St. Petersburg who was killed by lightning in 1753 during his attempt at measuring the intensity of the electric field in the atmosphere, caused Diviš to become interested in atmospheric electricity.<ref name=RP /> In letters, he proposed to several physicists (among them the Academies of Science in St. Petersburg and Vienna, as well as [[Leonhard Euler]]) to construct a "weather" machine"—a device that would suppress and prevent thunderstorms and lightning by constantly sucking atmospheric electricity out of the air. His theories were already, in his time, recognized as [[fringe science]], and thus ignored. When Diviš did not receive answers, he took it up on himself to build such a machine in his own parish.<ref name="Möhring">[https://e-pub.uni-weimar.de/opus4/frontdoor/index/index/docId/1374 Christa Möhring: Eine Geschichte des Blitzableiters.

The 1753 death of [[Georg Wilhelm Richmann]], a professor in St. Petersburg who was fatally struck by lightning while attempting to measure atmospheric electric fields, prompted Diviš to explore the nature of atmospheric electricity.<ref name="RP" /> He wrote to several prominent physicists—including members of the academies of science in St. Petersburg and Vienna, and to [[Leonhard Euler]]—proposing the construction of a "weather machine" designed to suppress thunderstorms by continuously discharging atmospheric electricity. His proposals were considered [[Fringe science|unorthodox]], even at the time, and were largely ignored. When he received no responses, Diviš proceeded to construct the device himself.<ref name="Möhring">[https://e-pub.uni-weimar.de/opus4/frontdoor/index/index/docId/1374 Christa Möhring: Eine Geschichte des Blitzableiters.

On 15 June 1754, he erected a forty-meter-high, free-standing pole in Přímětice, on which he mounted his "weather machine," consisting of several tin boxes and more than 400 metal spikes. A well-established theory at that time was that more pointed spikes would conduct electricity better. The pole was secured by heavy metal chains that inadvertently also grounded his construction, making it actually one of the first grounded lightning rods. He described his invention as being very effective at driving off storms: clouds formed when the pole was taken down and disappeared when erected again. He took these occasional observations as proof of his theory that the pointed spikes extracted latent electricity out of the atmosphere, deposing them safely before lightning could form. Several local newspapers and novelty papers from Southern Germany made reports on his attempts.<ref name="Möhring"/>
On 15 June 1754, he erected a forty-metre-high free-standing pole in Přímětice, on which he installed his "weather machine," consisting of multiple tin boxes and more than 400 metal spikes. The design was based on the then-prevalent belief that pointed spikes could efficiently conduct electricity. The pole was grounded by heavy metal chains, inadvertently making the structure one of the earliest grounded lightning rods. Diviš claimed the device was effective in dispersing storms: clouds allegedly formed when the machine was dismantled and dissipated when reinstalled. He interpreted these observations as evidence that the spikes were extracting latent electricity from the atmosphere, thereby preventing lightning formation. His experiments were reported in several local and regional newspapers in southern Germany.<ref name="Möhring" />


His findings were not well received in the scientific community, which largely decided to ignore him. In 1759, a drought threatened Přímětice's farmers, who now took action against their priests' attempts to control the weather and consequently destroyed the first "weather machine." This led to a dissent between Diviš and his "unruly flock" that only ended when the church superiors advised Diviš to stop his experiments. He was advised to unmount his second "weather machine," which he had then, for security reasons mounted on the tower of his church, and hand it over to the Louka abbey.<ref name="Möhring"/>
Despite these efforts, his work was not well received by the broader scientific community, which generally dismissed his theories. In 1759, during a period of drought, local farmers in Přímětice destroyed his weather machine, blaming it for the adverse weather conditions. The resulting conflict between Diviš and the parishioners only ended after church authorities intervened, instructing him to cease his experiments. He was ordered to dismantle a second weather machine he had installed on the church tower for security reasons, and to return it to Louka Abbey.<ref name="Möhring" />


Diviš continued to correspond with scientists and promote his own theory, which he called ''Magia naturalis''. [[Johann Ludwig Fricker|Fricker]] and [[Friedrich Christoph Oetinger|Oetinger]], two like-minded priests from [[Württemberg]] who had visited him during the experiments, helped him publish it abroad under the German name "Längst verlangte Theorie von der meteorologischen Electricité" ''(Much desired theory of the metereological electricity)'', in the same year that Diviš died. Again, the theory was largely ignored, though [[Johannes Nikolaus Tetens|Tetens]] reviewed them a few years after and called it a work of fantasy.<ref name="Möhring"/>

After years of obscurity, the memory of Diviš was reignited in the late 19th century.

Despite scientific reviews of Diviš's errors (among others, German physicist Meidinger, who compared evidence about early lightning rods in 1888; and Czech scientific historians Smolka and Haubelt in 2004/05), there are still claims that Prokop Diviš invented the lightning rod.

Prokop Diviš O.Praem. (Script error: No such module "IPA".;Template:Efn 26 March 1698[1] – 21 December 1765) was a Czech canon regular, theologian, and natural scientist. In an effort to prevent thunderstorms, he inadvertently developed one of the earliest grounded lightning rods.

Early life

Václav Divíšek[2] was born on 26 March 1698 in Helvíkovice, Bohemia (now in the Ústí nad Orlicí District, Czech Republic). As a child, he began his education at the Jesuit gymnasium in his hometown. In 1716, at the age of 18, he entered a gymnasium operated by the Premonstratensian abbey in the village of Louka, where he completed his basic studies in 1719.

Following this, Divíšek entered the novitiate of the abbey and took the religious name Prokop (or Procopius). He completed his novitiate the following year and professed his vows in the Premonstratensian Order. He then studied philosophy and theology in preparation for ordination to the Catholic priesthood, which took place in 1726. From 1729 to 1735, he taught philosophy at the abbey's gymnasium.[3] During this period, he was sent by his abbot to the Paris Lodron University in Salzburg (now the University of Salzburg) for advanced theological studies. In 1733, he completed his doctoral dissertation and was awarded the degree of Doctor of Theology.[4]

Upon returning to the abbey, Diviš resumed his duties as a canon regular and was appointed sub-prior. In 1736, he was assigned as pastor of the parish in Přímětice (now part of Znojmo), which was under the care of the abbey. He served in this role for five years before being recalled to the abbey in April 1741, where he was appointed prior.

In the spring of the following year, during the First Silesian War, the abbot, Antonín Nolbek, was arrested by forces of the Kingdom of Prussia and imprisoned. Diviš arranged for his release by paying a substantial ransom. However, this action displeased the abbot, who subsequently reassigned Diviš to the parish in Přímětice.[4]
