Title:    The SOLAR SYSTEM, with the Orbits of 5 remarkable COMETS.

Description:    An unusual solar system and comet map issued by Emanuel Bowen in 1747. The map shows the solar system with each planet given a circular orbit. The real highlight of the map is Bowen's identification of, in his words, '5 remarkable comets'. He does not name any of the comets, but does give dates and orbital periods, as then known:
  1. 1337 - ????. Most likely the Perseid Comet. Bowen does not offer a return date, but if it is the Perseid Comet, it reappeared in 1468, with 131 year window. The speculative nature of this comet's path is indicated by a dotted line.
  2. 1590 - ????. Another speculative comet, but most likely an early observation of Halley's Comet, which appeared in 1590.
  3. 1661 - 1789, 129 years. In all probability Comet Ikeya-Zhang which reappeared in 2002. The 18th century calculations performed by Johannes Hevelius giving this comet a 129 year orbit were apparently incorrect. The Chinese and Japanese astronomers Zhang Daqing and Kaoru Ikeya, respectively, recalculated the course of the comet following its 2002 appearance giving it a 366.51 year orbit, the longest of any periodic comet.
  4. 1680 - Doubtless this is the Great Comet of 1680, also called Kirch's Coment or Newton's Comet. Visible even during the day with a spectacular tail that bisected the night sky, this was one of the brightest comets in recorded history. This sungrazing comet was discovered by Gottfried Kirch and Eusebio Kino (better known in map circles for proving California's peninsular nature). This comet was also used by Isaac Newtown to test Kepler's laws. As a non-periodic comet it is not known when or if this spectacular satellite will return.
  5. 1682 - 1758, 75 1/2 years. Halley's Comet, which appeared in 1759 and has a 75-76 year orbit.
This chart was produced by Emanuel Bowen for issue as plate no. 1 in the 1747 first edition of his Complete System of Geography.

Cartographer:    Emanuel Bowen (1714-1767) had the high distinction to be named Royal Mapmaker to both to King George II of England and Louis XV of France. Based in London from 1714 onwards, Bowen was highly regarded for producing some of the largest, most detailed, most accurate and most attractive maps of his era. He is known to have worked with some of the most prominent cartographic names of the period including Herman Moll, John Owen, and Thomas Kitchin. Despite his renown and success, Bowen, like many cartographers, died in poverty. Upon Emanuel Bowen's death, his cartographic work was taken over by his son, Thomas Bowen (?? - 1790) who also died in poverty. Click here for a list of rare maps from Emanuel Bowen.
