1720 Homann, Doppelmayr & Eimmart Antique Twin Hemisphere Celestial Chart, Map. Planisphaerium Caeleste

1720 Homann, Doppelmayr & Eimmart Antique Twin Hemisphere Celestial Chart, Map. Planisphaerium Caeleste

Description:
This magnificent original hand coloured copper plate engraved antique double hemisphere celestial chart, showing constellations of the northern and southern hemispheres depicted as allegorical figures, animals and scientific instruments after Georg Christoph Eimmart (1638-1705) was published by Johann Baptist Homann and Johann Gabriel Doppelmayr (1677-1750) in ca 1720.

The stars are shown in six degrees of magnitude according to a key in the center between the hemispheres. The selection and style of the constellations followed that of Firmamentum Sociescianum sive Uranographia (1687) by the Polish astronomer Johannes Hevelius, whose name is noted in the subtitle of the chart. The subtitle further indicates that the chart also draws on the work of Edmund Halley, the British astronomer for whom Halley’s Comet is named. There are numerous variants of this chart published in Germany in the 18th century; this example, Planispaerium Caeleste by Homann, bears the name of the firm (Officina Homanniana) under the border in the lower margin, together with the name of Georg Christoph Eimmart (1638-1705), the Nuremberg astronomer.

Background:
The outer borders of the chart are decorated with six inset diagrams against a background of clouds including the planetary models of Tycho Brahe, Ptolemy, and Copernicus. The other 3 diagrams show the illumination of the moon by the sun, the revolution of the earth around the sun, and the effect of the moon on tides.
Various firms in Amsterdam, Nuremberg and Augsburg published double hemisphere constellation charts based on the work of George Eimmart titled Planispaerium Caeleste or Planisphaerium Coeleste during the first eight decades of the 18th century, which can be divided fundamentally into two different versions. The prolific Nuremberg publisher Johann Baptist Homann first published Planispaerium Caeleste in his Neuer Atlas in 1707, bearing the inscription Opera G.C. Eimmarti. prostat in Officina Homanniana, meaning Work of Georg Christoph Eimmart offered for sale by the Homann Workshop. That chart has six inset diagrams. Scholar Robert H. van Gent notes the existence of similar prints of this format published by de Wit, Funck, Schenck, and Lotter, as well as by R. & J. Ottens in Amsterdam. The other versions vary more considerably with the inclusion of a seventh inset diagram and a figural illustration in the upper center. These include ones published by Melchior Rein in Augsburg and by Georg Matthäus Seutter (1647–1756) in Nuremberg.
Johann Gabriel Doppelmayr and Johann Baptist Homann were frequent collaborators in producing celestial and astronomical charts for atlases published by Homann and issued under various titles. The major two compilations of Dopplemayr’s works were published by Homann Heirs: Atlas Coelestis in quo Mundus Spectabilis et in Eodem Stellarum Omnium Phoenomena Notabilia, issued as 30 plates in 1742, and the revised edition of this work Atlas Novus Coelestis, in quo Mundus Spectabilis, et in Eodem tam Errantium quam Inerrantium Stellarum Phoenomena Notabilia, issued in 1748 (with an additional plate depicting the solar eclipse of 1748).
Nonetheless, these charts have a complicated publishing history that is not fully known. Some of these charts had appeared in earlier Homann editions such as his first atlas, the Neuer Atlas (Nuremberg: 1707), Atlas von Hundert Charten (Nuremberg: 1712), Grossen Atlas (Nuremberg: 1716), and Atlas Portatilis Coelestis (Nuremberg: 1723). Homann also issued geographical maps in various atlases that may have included celestial plates (particularly composite atlases), and Homann and his heirs presumably sold separately issued maps. Further, three additional celestial and astronomy plates have been located in at least one Homann celestial compilation atlas (1742, 1748, or later), though not among the 30 maps of the standard issue of Atlas Coelestis in quo Mundus Spectabilis, namely Sphaerarum Artificialium Typica Repraesentatio (globes and armillary sphere), Neu invertirte Geographische Universal (clock), and Planisphaerium Caeleste (double hemisphere celestial chart).
Doppelmayr, a professor of mathematics at the Aegidien Gymnasium at Nuremberg, was an acclaimed German geographer and astronomer who wrote on astronomy, geography, cartography, trigonometry, sundials and mathematical instruments. He was also involved in the production of globes as part of a larger goal to bring the scientific ideas of the Enlightenment to a broader public. In service of that idea, Doppelmayr translated several works into German including Nicholas Bion’s 1699 work L’usage des globes célestes et terrestes, et des sphères [The Usage of Celestial and Terrestrial Globes and of Spheres]. Doppelmayr was elected to several scientific societies, including the Berlin Academy of Sciences, the Royal Society and the St. Petersburg Academy of Sciences.

Background: 
A large and impressive chart of the solar system, paying particular attention to the motions of the planetary bodies and the paths of comets. The chart was originally engraved in 1712 by Senex to accompany the lectures of the controversial theologian, astronomer, and polymath William Whiston. The chart was issued again in 1720 by Senex alone, and finally by Bowles and Sayer in the 1760s. The System is shown as a number of concentric orbits with the Sun at centre, criss-crossed by the broad elliptical paths of a number of comets. At top, the planets are shown pictorially, clumped together in an attempt to demonstrate scale. As the chart was engraved at the beginning of the eighteenth century, the outer planets past Saturn are not included. Earths moon is accorded an honorary spot among the planets, while the moons of the other planets are shown in the grand scheme as Satellites. The alchemical symbols for the zodiac are included along the outside ring of the System, and the chart is absolutely covered by explanatory text.

William Whiston (1667-1752) was an English mathematician, theologian, historian and religious writer. Born in Leicestershire, Whiston was a leading figure in popularising the ideas of Sir Issac Newton, who was his mentor and teacher. Whiston was a professor of mathematics at the University of Cambridge but was expelled from his position in 1710 due to his unorthodox religious beliefs and views. Whiston was a believer of Arianism, the idea that Christ is subordinate to God, the concept of Christ is based on the belief that the Son of God did not always exist but was begotten by God the Father. He also rejected the notion of eternal torment in hellfire. What especially placed him against church authorities, was he viewed the Trinity as a lie after extensive personal research convinced him the origin of the Trinity teaching to be pagan. Whiston wrote A New Theory of the Earth, published in 1696, in which he presented a description of the divine creation of the Earth, postulating that the earth originated from the atmosphere of a comet.

Background: 
Doppelmayrs best-known astronomical work is his Atlas Coelestis in quo Mundus Spectabilis et in eodem Stellarum omnium Phoenomena notabilia, circa ipsarum Lumen, Figuram, Faciem, Motum, Eclipses, Occultationes, Transitus, Magnitudines, Distantias, aliaque secundum Nic. Copernici et ex parte Tychonis de Brahe Hipothesin. Nostri intuitu, specialiter, respectu vero ad apparentias planetarum indagatu possibiles e planetis primariis, et e luna habito, generaliter e celeberrimorum astronomorum observationibus graphice descripta exhibentur, cum tabulis majoribus XXX, published in 1742 by the heirs of Homann in Nuremberg.
In this atlas, Doppelmayr collected most of the astronomical and cosmographical plates which he had prepared over the years for the Homann publishing firm and which had appeared in several of their atlases. These earlier atlases allow us to infer approximate dates for the design and preparation of many of Doppelmayr’s cosmographical plates.
The earliest ones are plates 2 and 11 as they were already included in Homann’s first atlas, the Neuer Atlas bestehend in auserlesenen und allerneusten Land-Charten ueber die gantze Welt, und zwar erstlich nach Astronomischer Betrachtung der Bewegung des Himmels in dem Systemate Copernico-Hugeniano, dann auch nach der nturlichen Beschaffenheit und geographischen Eintheilung der mit Wasser umgebenen allgemeinen Erd-Kugeln in ihre besondere Monarchien, Koenigreiche, Staaten und Laender (Nuremberg, 1707).
Plates 3 and 7 to 10 were first published in Homann’s Atlas von hundert Charten(Nuremberg, 1712), whereas plates 1, 4 and 15 to 25 can be dated between 1716 and 1724 as they were not included in Homanns Grossen Atlas (Nuremberg, 1716), but are mentioned in Hagers list of plates sold by Homann at his death in 1724.
The plates depicting the constellations (nrs. 16 to 25) were probably prepared and engraved in the early 1720s as the Atlas Portatilis Coelestis, oder compendiose Vorstellung des gantzen Welt-gebudes, in den Anfangs-grunden der wahren Astronomie (1723) of Johann Leonard Rost refers to a set of celestial hemispheres drawn by Doppelmayr. The choice and the style of the constellation figures on these plates is based on the Firmamentum Sobiescianum sive Uranographia (Danzig, 1687) of the Polish astronomer Johannes Hevelius, who also avoided the use of Bayer’s Greek letters for identifying the individual stars, and they were clearly executed before the publication of John Flamsteeds star catalogue (London, 1725) and star atlas (London, 1729).

Doppelmayr, Johann Gabriel 1677 - 1750
Johann Gabriel Doppelmayr (also spelled Doppelmaier or Doppelmair) was the son of the Nuremberg merchant Johann Siegmund Doppelmayr (1641-1686) and was born on 27 September 1677 (many early sources incorrectly give his year of birth as 1671). His father had an interest in applied physics and was one of the first to design a vertical vacuum air pump in Nuremberg.
Doppelmayr enrolled at the Ägidiengymnasium in 1689 and after completing his studies in 1696 enrolled at the nearby university of Altdorf to study law which he completed in 1698 with a dissertation on the Sun. He then attended lectures on mathematics and natural philosophy by Johann Christoph Sturm (1635-1703) which he completed in 1699 with his dissertation De visionis sensu nobilissimo, ex camerae obscurae tenebris illustrato. He continued his studies on physics and mathematics at the university of Halle where he also learned French and Italian.
In September 1700, Doppelmayr traveled to Berlin and from there, through Lower Saxony, to Holland where he visited Franeker and Amsterdam on his way to Utrecht where he stayed for a couple of months to continue his studies on physics and mathematics and to master the English language.
In April 1701, Doppelmayr went to Leiden where he stayed in the house of the astronomy professor Lothar Zumbach von Koesfeld and learned (probably in the Musschenbroek workshop) how to grind and figure telescope lenses. He then traveled to Rotterdam and in May to England where he visited Oxford and London.
After returning to Holland in the end of 1701, Doppelmayr spent another five months in Leiden, where he followed astronomy lessons from Lothar Zumbach von Koesfeld. After visiting Utrecht, Deventer, Osnabrück, Hannover, Kassel, Marburg, Gießen, Wetzlar and Frankfurt, Doppelmayr returned to Nuremberg in August 1702 and was appointed professor of mathematics at the Ägidiengymnasium in 1704, a position that he would hold until his death.
In 1723, he received an invitation to become the professor of mechanics at the Academy of St. Petersburg, but Doppelmayr declined and suggested that they should ask the Swiss mathematician Nikolaus Bernouilli for this position.
Doppelmayr died on 1 December 1750 in Nuremberg, and many believed that this was caused by the fatal effects of a powerful electrical shock which he had received shortly before while experimenting with a battery of electric capacitors. Other sources, however, suggest that Doppelmayr’s electrical experiments were performed several years earlier and were not the cause of his death.

Specifically this chart is an internal view of the sky centred on the vernal equinox in a gnomonic projection between the declinations 45° North and 45° South. Also depicted are the paths of the comets C/1577 V1 (observed by Tycho Brahe), C/1585 T1 (Tycho Brahe), C/1590 E1 (Tycho Brahe), C/1664 W1 (Giovanni Domenico Cassini), C/1665 F1 (Johannes Hevelius), C/1672 E1 (Giovanni Domenico Cassini), C/1677 H1 (Johannes Hevelius), C/1680 V1 (John Flamsteed) and C/1683 O1 (Johannes Hevelius).
Doppelmayr wrote on astronomy, geography, cartography, spherical trigonometry, sundials and mathematical instruments. He often collaborated with the cartographer Johann Baptista Homann (1664-1724), a former Dominican monk from Oberkammlach in Schwabia who in 1688 had settled in Nuremberg and became a map engraver for the publishing firms of Jacob von Sandrart and David Funck.
In 1702, Homann founded an influential cartographic publishing firm that after his death was continued by his son Johann Christoph Homann (1703-1730) and after the latters death by his friend Johann Michael Franz (1700-1761) and his stepsisters husband Johann Georg Ebersberger (1695-1760) under the name Homännische Erben. The publishing firm remained in business under different names until 1848. (Ref: Adelung, J.Chr., Johann Gabriel Doppelmayr; Cantor, M., Johann Gabriel Doppelmayr)

Background:
During the Renaissance, Nicolaus Copernicus proposed a heliocentric model of the solar system. His work was defended by Galileo Galilei and expanded upon by Johannes Kepler. Kepler was the first to devise a system that correctly described the details of the motion of the planets around the Sun. However, Kepler did not succeed in formulating a theory behind the laws he wrote down. It was Isaac Newton, with his invention of celestial dynamics and his law of gravitation, who finally explained the motions of the planets. Newton also developed the reflecting telescope.
Improvements in the size and quality of the telescope led to further discoveries. The English astronomer John Flamsteed catalogued over 3000 stars. More extensive star catalogues were produced by Nicolas Louis de Lacaille. The astronomer William Herschel made a detailed catalog of nebulosity and clusters, and in 1781 discovered the planet Uranus, the first new planet found. The distance to a star was announced in 1838 when the parallax of 61 Cygni was measured by Friedrich Bessel.
During the 18–19th centuries, the study of the three-body problem by Leonhard Euler, Alexis Claude Clairaut, and Jean le Rond dAlembert led to more accurate predictions about the motions of the Moon and planets. This work was further refined by Joseph-Louis Lagrange and Pierre Simon Laplace, allowing the masses of the planets and moons to be estimated from their perturbations.
Significant advances in astronomy came about with the introduction of new technology, including the spectroscope and photography. Joseph von Fraunhofer discovered about 600 bands in the spectrum of the Sun in 1814–15, which, in 1859, Gustav Kirchhoff ascribed to the presence of different elements. Stars were proven to be similar to the Earths own Sun, but with a wide range of temperatures, masses, and sizes.

Hall, William Henry
Hall was responsible for a significant publication in the middle of the 18th century The new royal encyclopedia; or, complete modern universal dictionary of arts and sciences on a new and improved plan . containing a digest and display of the whole theory and practice of the liberal and mechanical arts comprising a general repository of ancient and modern literature . including all the material information that is contained in Chamber s Cyclopedia, the Encyclopædia Britannica, and the French Encyclopædie . first published in 1788 going into many re-issues over the next 50 years.
The three volume set contained 153 copper-plate prints and maps, including some folding maps. Contained many brief encyclopedic entries in alphabetical orders plus longer, mainly illustrated, sections (systems or treatises) on a variety of subjects: Aerology; Aerostation (hot air balloons); Agriculture; Algebra; Amphibiology; Anatomy; Annuities; Architecture; Arithmetic; Astronomy (includes plates of telescopes); Book-Keeping; Botany; Brewing; Chronology; Chymistry; Comparative Anatomy; Concology; Dialling; Distillation; Drawing; Earth; Earthquakes; Electricity; Entomology; Farriery; Fencing; Fluxions; Fortification; Gardening; Geography (this section includes six folding maps); Geometry; Globes; Grammar; Heraldry; Hydrostatics and Hydraulics (one plate included a diving bell); Icthyology; Knighthood; Logic; Mammalia (included a plate showing whales); Mechanics; Medicine; Mensuration and Gauging; Miscroscopic Apparatus (microscopes); Midwifery; Military Affairs; Music; Natural History; Naval Affairs; Navigation (includes a folding map showing Cooks voyages); Optics; Oratory; Ornithology; Peerage; Perspective; Pneumatics; Projectiles; Steam Engines; Surgery; Surveying; Trigonometry; Vermeology; Volcanos; and War. Hard to find a complete set, as many have been broken up for their handsome copper plate engravings and maps.
