A 17th century chart of Astrological aspects

A celestial 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. The plate was engraved by Jan van Loon for 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, most decorative celestial atlas ever produced. It was first issued in 1660; this example comes from the second edition published a year later , with a plate number added.
