ptolemäischen

Ptolemäischen refers to things associated with Claudius Ptolemy, a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet. His most influential work in astronomy was the Almagest, in which he described a geocentric model of the universe. This Ptolemaic system, with the Earth at the center of the cosmos and celestial bodies revolving around it in epicycles and deferents, dominated astronomical thought for over 1400 years. The term "Ptolemaic" is often used to describe this specific model.

In geography, Ptolemy's Geographia was another significant work. It provided a comprehensive atlas and a system of geographical coordinates, influencing cartography for centuries. The "Ptolemaic" approach to mapping often involved projecting the spherical Earth onto a flat surface, a method that had both strengths and limitations.

In astrology, Ptolemy's Tetrabiblos laid out principles of astrological interpretation that became foundational for the practice. Therefore, "Ptolemäischen" can also relate to specific astrological theories and methods derived from his writings. The legacy of Ptolemy is extensive, and "Ptolemäischen" serves as a shorthand to connect various scientific and pseudoscientific concepts and systems to his influential contributions.
