1% IS FEW. we are talking about high society here, women were mostly tools, and they were not really allowed to be taught to ride horses, keep in mind that 'not really allowed' in this situation means that they were not expected to do so, it wasn't law, but people thought that woman riding horses was un-needed, and the woman that wanted it would be laughed at.
But I didn't talk only about just riding horses. Women were really not allowed to read and write books with politics, I mean they weren't even allowed to have pockets so they wouldn't be carrying weapons or poisons. Even in 16th century noble women were mostly tools.
I live in Europe, specifically in Greece, you don't get to say I don't know about it when even middle schools teach those things here. And you are saying that you studied from documents and journals? yes woman did occasionally work in jobs that men did, who denied that? but they were looked down upon, and they were way too few, we are talking about less then even 0.1% of people working those jobs being woman. But as I said, we are talking about high society here. and the things I said remain true. nobles didn't like their woman riding horses, and reading/writing political books.
