Theoria Planetarum Primariorum,..
Figure illustrating the movements of the planets according to the theories of Kepler and Copernicus, who both advocated the heliocentric theory. Unlike Copernicus, who believed that the planets had circular orbits, Kepler theorised elliptical orbits and a close relationship between geometry and cosmology. Four notes surround the illustrations and explain Kepler's theories as well as those of Ismael Bullialdus, Seth Ward and Nicolaus Mercator.
Homann / Doppelmayer, J.G. (1664-1724)
Johann Babtiste Homann (1664-1724) was born in Oberkammlach, the Electorate of Bavaria. Although educated at a Jesuit school, and preparing for an ecclesiastical career, he eventually converted to Protestantism and from 1687 worked as a civil law notary in Nuremberg. He soon turned to engraving and cartography; in 1702 he founded his own publishing house. Homann acquired renown as a leading German cartographer, and in 1715 was appointed Imperial Geographer by Emperor Charles VI. Giving such privileges to individuals was an added right that the Holy Roman Emperor enjoyed. In the same year he was also named a member of the Prussian Academy of Sciences in Berlin. Of particular significance to cartography were the imperial printing privileges (Latin: privilegia impressoria). These protected for a time the authors in all scientific fields such as printers, copper engravers, map makers and publishers. They were also very important as a recommendation for potential customers. In 1716 Homann published his masterpiece Grosser Atlas ueber die ganze Welt (Grand Atlas of all the World). Numerous maps were drawn up in cooperation with the engraver Christoph Weigel the Elder, who also published Siebmachers Wappenbuch. Homann died in Nuremberg. He was succeeded by the Homann heirs company, which was in business until 1848. The company was known as Homann Erben, Homanniani Heredes, or Heritiers de Homann abroad.
The history of western astrology can be traced back to pre-Christian times in Babylonia or Mesopotamia and Egypt. Its basic principles of interpretation and calculation, which are still recognizable today, were learned by astrology in the Hellenistic Greek-Egyptian city of Alexandria. Astronomy emerged from it as meaningless observation and mathematical recording of the starry sky, and it remained associated with it for a long time as an auxiliary science. Astrology had an eventful history in Europe. After the elevation of Christianity to the state religion in the Roman Empire, it was partly fought, partly adapted to Christianity and temporarily pushed aside. In the course of the early Middle Ages, astrology, especially the learned astronomy-astrology, revived in the Byzantine Empire from around the late 8th century, as also somewhat later in the Muslim Al-Andalus on the Iberian Peninsula. From the later High Middle Ages and especially in the Renaissance to the 17th century, it was widely regarded as a science in Europe, always combined with astronomy in the quadrivium of the seven liberal arts that had been taught at universities. In the course of the Enlightenment, however, it lost its plausibility in educated circles.
