The correct answer to this open question is the following.
The emergence of female artists in eighteen-century Europe was a consequence of the Enlightenment times in this region when science, political thinking, and arts opened new ways to openly express human ideas never before heard.
The prevailing social and cultural trends that affected these artists and their work favored the support for painters like the above-mentioned, who had the best opportunities to share their work than in previous Middle Ages times. Although at that time the role of women was not so prominent and was always behind the shadow of men, some artists could have the social connections to exhibit their paintings.
I would like to refer to the case of Angela Kauffman, a Swiss painter (1741-1807). She was considered a Neoclassic painter that could successfully exhibit her works in places such as Italy and Great Britain. She specialized in landscape and decorative figures.
