Hemelkaart van de aarde volgens het stelsel van Ptolemaeus 1660 - 1708

Johannes van Loon's "Hemelkaart van de aarde volgens het stelsel van Ptolemaeus" (c. 1660-1708) depicts a celestial globe within a Ptolemaic world system. The globe, tilted on its axis, is surrounded by an intricate network of circles representing different astronomical phenomena. The image is further decorated with cherubs and allegorical figures, highlighting the historical significance of the Ptolemaic model in understanding the cosmos. This detailed engraving, measuring 432 mm by 509 mm, was likely intended for scientific and educational purposes, offering a visual representation of the prevailing cosmological theories of the 17th century.
