Hypatia- Philosopher, astronomer, mathematician, inventor of the astrolabe, advocate against religious repression and violence. Fearing her strong feminism, intellect, political power and influence, early christians stripped her naked, dragged her body through the street, and stoned her to death. The mob then burned her body along with the first university and largest library of the time. Most of her work has been lost; her discoveries would not be known again until 1200 years later.
