In page Maria Cunitz:

"

Urania propitia did not have much of an impact on late 17th-century astronomy. A large contribution to this fact has to do with Cunitz publishing her work in an isolated printing establishment in Olesnica, and there were only a few copies of the Urania propitia made. No one really mentioned Urania propitia, except a mid-century Parisian astronomer named Ismael Boulliau.[2] However, Boulliau "only commented on the Urania propitia and thought his work was better and more accurate than Cunitz's work."[citation needed]
