Ram-esses, or "sheep" as they are commonly known today, was the name taken by the first female Pharoahs, hoping to inspire the masses to follow them, just as sheep follow one another, and overcome the all male tradition.
This sleight of hand was revived by the Greek philosophers, most of whom where in fact philosophesses, but sporting fake bushy beards.
They also sometimes took female animals as their names, most famously "Dogess", later corrupted "Diogenes". Apparently quite a looker once the facial hair was pulled away, the old master of her by Langetti caused a scandal, and he was later forced to overpaint her breasts under threat of torture.
