Systema Mundi Tychonicum - J. Doppelmayr 1742

Engraved plate depicting the Tychonic cosmological system, issued from the Atlas Novus Coelestis by Johann Gabriel Doppelmayr and published by the heirs of Johann Baptist Homann. The composition illustrates the model developed by Tycho Brahe, within the context of 18th-century astronomical cartography.

The layout is defined by clarity and decorative richness, with a detailed representation of planetary orbits, the positions of Earth and the Sun according to the Tychonic system, and additional symbolic and didactic elements. The engraved line, refined and analytical, provides an ordered reading of the cosmological structure, balancing scientific function and visual presentation.

This example represents German cartographic production of its time and belongs to the tradition of scientific and astronomical cartography, constituting a significant testimony to the transitional phase between geocentric and heliocentric models.

Art Historical Note
Johann Gabriel Doppelmayr stands among the leading figures of early 18th-century astronomical cartography, distinguished by scientific rigor, didactic clarity, and engraving quality.

The work belongs to the Atlas Novus Coelestis, conceived as a systematic compendium of contemporary astronomical knowledge. Such plates, often intended for a learned audience, document the historical context of competing cosmological models between the 16th and 18th centuries.
