A 17th century chart of Astrological aspects

A chart illustrating the aspects of Astrology (i.e. conjunction and opposition) of the Zodiac and planets, with a globe at the centre, showing the Northern Hemisphere with California as an island. This chart was engraved by Jan van Loon and published in the 'Atlas Coelestis; seu Harmonia Macrocosmica', the only celestial atlas to be produced in the Netherlands before the nineteenth century. It was a compilation of maps of the Ptolemaic universe and the more modern theories of Copernicus and Brahe, and remains the finest and most highly decorative celestial atlas ever produced. It was originally published by Jan Jansson in 1660: this chart comes from Schenk & Valk's reissue.
