Maria Cunitz (1610 – 22 August 1664) was a Silesian astronomer. She authored the book *Urania propitia*, which provided new tables, new ephemera, and a simpler working solution to Kepler's second law for determining the position of a planet on its elliptical path.

Lore & Background
The year of her birth is uncertain; no birth or baptism documents have been found. Elias, a physician and amateur astronomer, had been her tutor and encouraged her pursuit of astronomy. After the war, they returned to Pitschen in Silesia.
Reader's Guide
The book provided new tables, new ephemera, and a more elegant solution to Kepler's problem—determining a planet's position in its orbit as a function of time. Published in both Latin and German to increase accessibility, *Urania propitia* is also credited with contributing to the development of the German scientific language. Despite its innovations, the work had little impact on late 17th-century astronomy, partly because it was printed in an isolated establishment in Olesnica with only a few copies made.
Did You Know?
- During the Thirty Years' War, she arranged astronomical tables based on Kepler's Rudolphine Tables while taking refuge in a Cistercians convent in Olobok, Poland.
- Her work *Urania propitia* was published in both Latin and German to increase accessibility.
Frequently Asked Questions
Who is Maria Cunitz?
Maria Cunitz (1610–1664) was a Silesian astronomer widely regarded as the most prominent woman working in the field during the early modern period. She is best remembered for her mathematical and observational contributions to planetary astronomy.
What is Maria Cunitz's major publication?
Her key work is *Urania propitia*, a volume that presented fresh astronomical tables, updated ephemera, and a more accessible method for applying Kepler's second law to calculate a planet's position along its elliptical orbit.
How did Maria Cunitz relate to Kepler's Rudolphine Tables?
Cunitz took Kepler's complex Rudolphine Tables and developed a streamlined working solution that made it easier for practitioners to determine where a planet sat on its elliptical path without wading through the full set of calculations.
Where was Maria Cunitz from and when did she live?
She was born in Wohlau (present-day Wołów, Poland) in 1610, though some older records list 1604, and she passed away on 22 August 1664. She is identified as Silesian in nationality.
Why does Maria Cunitz matter in the history of astronomy?
She stands out as the leading female astronomer of her era and is credited with making Kepler's otherwise dense planetary mathematics more usable for working astronomers of the seventeenth century.
