I’ve never heard of Catalina de Erauso before reading the excerpt from her memoir.
Her story is interesting and she is undoubtedly a very brave woman but it’s seems far too fantastical to be real; for example, her almost supernatural ability to not be discovered (ie. how her own parents didn’t recognize her), and the reaction of the Catholic Church to her activities disguised as a man (at this time, one would assume that Catalina de Erauso would have been at the least excommunicate but instead the Church allowed her to continue her adventures – albeit under the strange condition that she remained a virgin) do not strike me as realistic .
Her tale is full of action, adventure, and improbably luck that it cannot be seen as anything but fictional from my point of view. Regardless, Catalina de Erauso desired to have the same rights & freedoms as men and she was very brave for acting against prominent values in of her time.
Other than the question of whether or not her story is fact or fiction, there is the matter of whether or not she was a hero or a ‘villain’ – some praise the ‘lieutenant nun’ as a hero yet some of her actions detract from this idealized image.
I guess we’ll never know the real story of Catalina de Erauso.
