Urania Propitia

As Maria Cunitz was the daughter of both a physician and mathematician, it was her ability to grasp complex mathematics quickly and transcribe her findings as a polyglot that allowed her to do what[specify] few women had done before her.

In Urania Propitia, Cunitz removed logarithms from Kepler's work, which increased the accuracy and simplified the calculations from the Rudolphine Tables.

Using the geometry and spherical astronomy from part one, Cunitz brings the rotational motions of the planets and moons into light using various mathematical formulas.

This includes the use of the "golden astronomical number", the parallax of the moon and sun in a variety in longitude, latitude, altitude, etc..., and a catalog of other fixed stars in the universe.

It was described by Noel Swerdlow as "the earliest surviving scientific work by a woman on the highest technical level of its age.

This suggests that Maria Cunitz both saw Urania as her muse while also making strides for women as scientists, because she could be so easily compared to the ancient Greek astronomer.
