Urania Propitia: Maria Cunitz’s 1650 astronomical work, containing simplified tables for calculating planetary positions. This is the book through which Cunitz made her astronomical methods available.
Johannes Kepler: A German astronomer and mathematician who formulated laws of planetary motion and advanced heliocentric astronomy. Cunitz’s work reworked calculations associated with Kepler’s astronomy.
Elias von Löwen: A physician and astronomer, and Maria Cunitz’s husband and collaborator. He supported Cunitz’s astronomical work and helped circulate her book.
Scientific publishing: The production and circulation of works that communicate scientific knowledge. Print allowed Cunitz’s tables and explanations to reach scholars beyond her household.
Rudolphine Tables: Astronomical tables published by Johannes Kepler in 1627 to predict the positions of the planets. Cunitz adapted Kepler’s planetary calculations into a more accessible form.
Heliocentrism: The astronomical model in which Earth and other planets orbit the Sun. Keplerian planetary predictions, which Cunitz recast, belonged to heliocentric astronomy.
Johannes Hevelius: A Polish astronomer known for detailed observations of the Moon and comets. Hevelius later represented another prominent early modern astronomer working outside major institutions.
Astronomical tables: Numerical listings used to calculate or predict celestial positions and events. Cunitz’s work belongs to a long tradition of tabular astronomy.
Kepler's laws of planetary motion: Three mathematical laws describing how planets orbit the Sun, formulated by Johannes Kepler. The planetary predictions in Cunitz’s tables rested on Kepler’s orbital theory.
Thirty Years' War: A series of conflicts in Central Europe from 1618 to 1648, devastating many German territories. War and displacement shaped the circumstances in which Cunitz prepared her work.
