Astrologers
Tycho Brahe, born Tyge Ottesen Brahe, more commonly called Tycho, was a prominent Danish astronomer, astrologer, and alchemist of the Renaissance.
As a young man he traveled extensively throughout Europe, studying in Wittenberg, Rostock, Basel, and Augsburg and acquiring mathematical and astronomical instruments. In 1572 Tycho unexpectedly even for himself discovered a new star in Cassiopeia, and the publication of this turned the young Dane into an astronomer of European reputation. For further astronomical research he established an observatory and gathered around him modern progressive scientists.
Besides practicing astronomy, Tycho was an artist, scientist, and craftsman, and everything he undertook or surrounded himself with had to be innovative and beautiful. He even founded a printing house to produce and bind his manuscripts in his own way, and he perfected sanitary ware for convenience. His development of astronomical instruments and his work in measuring and fixing the positions of the stars laid a solid foundation for future discoveries.
Tycho's observations - the most accurate possible before the invention of the telescope - included a comprehensive study of the solar system and the precise positions of more than 777 fixed stars. What Tycho accomplished using only his simple instruments and intellect remains a remarkable achievement of the Renaissance.
Bonetus de Latis or Jacob ben Emanuel Provenzale was a French physician and astrologer of Jewish origin.
Originally from Provence, France, he was a rabbi, and in Rome became physician to Pope Alexander VI and later Pope Leo X. Latis is known mainly as the inventor of the ring-shaped sundial, an astronomical circular dial that could be used to measure solar and stellar altitudes and determine the time with great accuracy both day and night. These clocks were portable and easy to use for navigation. Latis also wrote a treatise known among scholars about the astrolabe ring (1492-1493).
Johann Dryander, born Johann Eichmann, was a German medical anatomist, mathematician and astrologer.
He studied anatomy and medicine at the University of Paris and the University of Erfurt, and in 1535 became professor of medicine at the University of Marburg. A year later, Dryander performed two public autopsies, making the first illustrated description of the dissection of the human brain. Dryander titled his book Anatomiae, hoc est, corporis humani dissectionis pars prior ("Anatomy, that is, the dissection of the human body, part one," suggesting a sequel, which, however, did not follow.
His work made a significant contribution to the development of modern anatomy. Toward the end of his life, Dryander also dabbled in astrology and mathematics.
Johann Sigismund Elsholtz (also Elßholtz, Elßholz, Elsholz, Latin Elsholtius) was a German physician, botanist and chemist, a pioneer of hygiene.
Elsholtz studied at the universities of Wittenberg, Königsberg, and Padua, where he received his doctorate. In 1654, he published Anthropometry, written for artists and astrologers as well as students of medicine and physiognomy. The book also explored the supposed relationship between the proportions of the human body and morbidity. Elsholtz was a very versatile scientist and worked in the fields of horticulture, botany, alchemy, astrology, dietetics and medicine, among others.
Elsholtz was later appointed court botanist, alchemist and physician to Elector Friedrich Wilhelm of Brandenburg (1620-1688), and in 1657 was placed in charge of his botanical gardens in Berlin, Potsdam and Oranienburg. In 1672 his treatise Vom Garten-Baw: Oder Unterricht von der Gärtnerey auff das Clima der Chur-Marck Brandenburg was published in Berlin. ("From the Garden Bow or Lessons in Gardening in the Climate of Chur-Marck Brandenburg." It presents the latest gardening techniques for the German climate, discussing flower gardens and their design, vegetable gardens, medicinal gardens, and vineyard care and design.
Elsholtz was a German pioneer in the field of cleanliness and nutrition. Generally speaking, the term "hygiene" first appeared in German in 1682 in his Dietetikon. It is the term he uses to describe the principle of maintaining good health. In his book, the doctor makes recommendations for healthy eating and drinking. He calls for clean water and good air and emphasizes the importance of personal hygiene. Elsholtz was one of the first to administer intravenous injections to people around 1665.
Robert Fludd was a prominent English Paracelsian physician with both scientific and occult interests. He is remembered as an astrologer, mathematician, cosmologist, Qabalist and Rosicrucian.
Fludd is best known for his compilations in occult philosophy. He had a celebrated exchange of views with Johannes Kepler concerning the scientific and hermetic approaches to knowledge.
Georg Galgemair was a German mathematician and astrologer.
He was born into the family of the burgomaster of Donauwörth, was a pupil of Philip Apian, and then a master of mathematics at the University of Tübingen in 1585. After completing his studies, Galgemair began teaching at Lauingen in 1588.
His work on proportional circles led to the development of gnomonics. In the history of science, Galgemair is known for his works on mathematical instruments. As a calendar maker, he succeeded in 1606 in obtaining an imperial privilege for his calendars.
Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets move around the Sun in elliptical orbits.
Kepler created the three fundamental laws of planetary motion. He also did seminal work in optics and geometry, calculated the most accurate astronomical tables, and made many inventions and discoveries in physics on which further scientific discoveries by advanced scientists were based.
Nostradamus (French: Michel de Nostredame) was a French physician-pharmacist, writer, poet, astrologer and alchemist.
Nostradamus was born into a family of baptized Jews and studied various sciences in Avignon. At that time the plague was rampant in Europe, and Nostradamus decided to become a healer, in 1526 he even invented an anti-plague medicine, and later received a degree of Doctor of Medicine. He began his medical practice around the 1530s in Agen. During the plague outbreaks in Aix and Lyon in 1546-1547, he gained fame for his innovative treatments. Nostradamus described his methods of dealing with epidemics in several medical works. In addition to medicine, he also practiced astrology.
Nostradamus gained worldwide fame thanks to his gift as a seer. He began making prophecies around 1547 and first published them in 1555 in a book called Centuries. The book was written in rhymed quatrains - catrines - with predictions of future events in European history. Some of his prophecies were close to the truth, and the fame of the visionary Nostradamus reached the court of Catherine de Medici, who ordered him to compile horoscopes of her children. In 1564 he was appointed physician to Charles IX, to whom he also made several predictions that came true.
Nostradamus's book of prophecies was a huge success, and it still arouses interest, but he wrote allegorically and many of the katrines cannot be interpreted unambiguously.
Regiomontanus, real name Johannes Müller, was a 15th-century German astronomer and mathematician, one of the first printers.
The son of a miller, he entered the University of Leipzig at the age of 11 and later transferred to the University of Vienna. In 1452, Regiomontanus earned a bachelor's degree and then a master's degree. With his teacher, the mathematical astronomer Georg von Peyerbach (d. 1461), he spent the next years practicing astronomy and astrology, including observations of eclipses and comets, making astronomical instruments, and compiling horoscopes for the court of Holy Roman Emperor Frederick III.
Regiomontanus was also seriously involved in mathematics, publishing his major work on trigonometry, On All Kinds of Triangles (1462-1464). From 1467 to 1471, Regiomontanus lived in Hungary as astrologer to Hungarian King Matyas I and Archbishop Janos Vitez. Then in Nuremberg, Germany, he opened an instrument workshop, established a printing house, and continued his planetary observations. The scholar planned to print extensive publications on classical, medieval, and modern mathematical sciences, but not all plans came to fruition.
Paolo Ricci (Italian: Paolo Ricci, Latin: Paulus Ricius, German: Paul Ritz), also known as Ritz, Riccio, or Paulus Israelita, was a humanist convert from Judaism, a writer-theologian, Kabbalist, and physician.
After his baptism in 1505 he published his first work, Sol Federis, in which he affirmed his new faith and sought through Kabbalah to refute modern Judaism. In 1506 he moved to Pavia, Italy, where he became a lecturer in philosophy and medicine at the university and met Erasmus of Rotterdam. Ricci was also a learned astrologer, a professor of Hebrew, philosophy, theology, and Kabbalah, a profound connoisseur and translator of sacred texts into Latin and Hebrew, and the author of philosophical and theological works.
Paolo Ricci was a very prolific writer. His Latin translations, especially the translation of the Kabalistic work Shaare Orach, formed the basis of the Christian Kabbalah of the early 16th century.
Thomas Ring was a German astrologer, painter and poet.
Thomas Ring studied in the class of the graphic artist Emil Orlik. He was intensively involved in the emerging expressionism and abstract painting.
As a 'degenerate painter' and (from 1927) a member of the Communist Party, he and his family emigrated to Austria at the end of 1932. In 1943 and 1944 he worked at the Institute of Psychology at the University of Strasbourg during the Second World War. After Strasbourg was liberated from the Nazis by the Allies, both he and his wife were imprisoned in a French prisoner-of-war camp.
After his liberation from the camp, Thomas Ring returned to Austria in 1946. In 1952 he settled in the countryside in the Black Forest, Germany.
He took part in three exhibitions (1961 in Berlin, 1971 and 1973 in Cologne), in which he was presented as a constructivist and a member of Der Strum. In 1974, Dumont Studio Cologne held a solo exhibition with forty-seven of his works.
Giuseppe Rosaccio was an Italian physician, astronomer, cosmographer and cartographer.
Rosaccio graduated from the University of Padua, studied philosophy, medicine and law, and worked as a physician and judge. He became famous for a series of works that popularized a number of scientific disciplines. Some of his books deal with astrological medicine, specific diseases and their remedies, and the distillation of medicines from plants.
Giuseppe Rosaccio wrote about forty works on various topics of interest to him, but the main one was geography. He wrote an essay on the Muslim religion and treatises on geography, cosmography, astronomy, and astrology, which became very popular and were repeatedly reprinted.
Rosaccio created many atlases and small-format geographical works. Among his works is Ptolemy's Geography, which contains many indexes and is written in Italian (1599). He also authored a large map of the world (1597), and a large map of Italy and Tuscany (1609). His book Journey from Venice to Constantinople includes maps of the route with brief texts, that is, it is essentially an illustrated version of a pilgrimage to the Holy Land.
