The Harmonia Macrocosmica is a star atlas written by Andreas Cellarius and published in 1660 by Johannes Janssonius. The first part of the atlas contains copper plate prints depicting the world systems of Claudius Ptolemy, Nicolaus Copernicus and Tycho Brahe. At the end are star maps of the classical and Christian constellations, the latter ones as introduced by Julius Schiller in his Coelum stellatum christianum of 1627. Because the atlas also contained plates supporting the then popular view of the Catholic Church, the book was not placed on the Index Librorum Prohibitorum.
History
In the foreword to his Chronologica, Gerard Mercator stated the intention to publish an atlas which would cover everything of the then-known cosmos, geography and history of the earth. During his life, Mercator published five volumes of his atlas, the last one being published by his son Rumold. After Mercator's death the Amsterdam cartographer Johannes Janssonius took over the project. He and fellow-cartographer Hendricus Hondius published their Novus Atlas in 1636, which featured over 320 maps in four languages. In 1660, Andreas Cellarius' Harmonia Macrocosmica was published as the seventh volume of the project. With the final addition of a volume describing the cities of the world from 1657, the project was finally completed.
Origins of the engravings
Of the various engravers and authors who worked on the plates of the atlas, only two have signed their work. The frontispiece of the atlas was created by Frederik Hendrik van den Hove and ten other plates were engraved by Johannes van Loon. Moreover, all the designs of the classical constellations were taken from the ones created by Jan Pieterszoon Saenredam.
