The city of Alexandria in Egypt was one of greatest centers of learning in the ancient western world.

The city was founded by Alexander the Great, and the family of his named successor, Ptolemy, became the rulers of Egypt until the death of Cleopatra VII, so the culture of the city was a mixture of Greek, Egyptian and Roman.

The Library of Alexandria contained all of the known “books” of that time. Scholars came from all over the world to study there. The Library was accidentally burned by Julius Caesar during his conquest of Egypt and most of the books were moved to the Seraphium. The Alexandran Museum, a type of university, was housed in the Library and, later, the Seraphium.

The Seraphium was destroyed in 391 AD by Theophilus, the archbishop of Alexandria, under orders from the Roman emperor to destroy all pagan temples. (The Emperor Constantine adopted Christianity as the religion of the Roman Empire.) The Seraphium was destroyed because it included a temple of Serapis. Theophilus later built a church on the site.

Hypatia was the daughter of Theon of Alexandria, an eminent mathematician and astronomer, and author of a student edition of Euclid’s Elements. Theon was the last known member of the Alexandran Museum. Hypatia succeeded her father as the leading teacher of science, mathematics and philosophy of her time, and one of the first women to teach those subjects. Her lessons included how to design an astolabe, a portable astronomical calculator, that would be used until the 19th century.

Hypatia was a philosopher in the Neoplatonic school, a belief system in which everything emanates from the One.

Her lectures became immensely popular, including attracting Christian students. Some of those students became leaders in the early Christian church and incorporated her ideas into their Christian faith. Her student, Synesius, became a bishop in the Christian church and incorporated Neoplatonic principles into the doctrine of the Trinity.

Hypatia became very influential in Alexandria’s politics, and was often consulted by the city’s leaders. She was a close friend of Orestes, the governor of Alexandria. Although Orestes was a Christian, he didn’t want to cede power to the church.

Theopolis was succeeded as archbishop in 412 AD by his nephew, Cyril. Cyril continued his uncle’s attacks on other faiths. Cyril competed with Orestes for control of Alexandria. The struggle for power came to a peak following a massacre of Christians by Jewish extremists. Cyril led a crowd that expelled all Jews from Alexandria and looted their homes and temples.

Orestes refused Cyril’s attempts at reconciliation and Cyril’s monks were unsuccessful in an attempt to assassinate Orestes.

Hypatia was an easier target. She didn’t have guards protecting her. She was a pagan who publicly spoke about a non-Christian philosophy. A rumor spread that she was preventing Orestes and Cyril from settling their differences.

In March, 415 AD, Peter the Lecter and his mob captured Hypatia, dragged her into a church, stripped her naked, and hacked her to pieces. To avoid having her venerated as a martyr, they cremated her remains.

Despite those efforts, Hypatia was remembered and revered as a martyr by the Christians of Byzantium, and today she is a symbol of Enlightenment values.

The story of Hypatia is still important today. Some fundamentalist Christians and other groups reject science. The Trump administration is withdrawing funding from scientific research at the National Science Foundation and the National Institutes of Health, and attacking academic freedom. We are also seeing a resurgence in censorship and book banning.

The abandonment of freedom of thought and expression could lead to a new dark age for the United States.
