<p>Alexandria, 391 AD: Hypatia teaches astronomy, mathematics, and philosophy. Her student Orestes is in love with her, as is Davus, her personal slave. As the city&#39s Christians, led by Ammonius and Cyril, gain political power, the institutions of learning may crumble along with the governance of slavery. Jump ahead 20 years: Orestes, the city&#39s prefect, has an uneasy peace with Christians, led by Cyril. A group from the newly empowered Christians has now taken to enforce their cultural hegemony zealously; first they see the Jews as their obstacle, then nonbelievers. Hypatia has no interest in faith; she&#39s concerned about the movement of celestial bodies and "the brotherhood of all". Although her former slave doesn&#39t see it that way.</p>
