It was not she who was strange, but the world that found her so

She lectured, annotated, calculated. What her age found strange was not the work but who was doing it.

Apply this column's title to her and it fails. There was nothing strange about Hypatia. She taught mathematics and astronomy in Alexandria, students came from far away, and the city's officials sought her counsel. An entirely ordinary scholarly life.

What was strange was the record. Letters of the time and lexicons of later centuries introduce her with a qualifier — although a woman — that no man doing the same work ever received.

Her work was not glamorous. She annotated Ptolemy's astronomical tables and Diophantus's Arithmetica: writing out the hard steps of a calculation, recomputing figures that copyists had garbled. She discovered nothing new.

In 415 she was killed by a mob, in the middle of a political conflict in Alexandria that tangled religious tension with a power struggle between the prefect and the bishop. She was identified as belonging to one side.

For fifteen centuries afterwards she was put to many uses. The Enlightenment made her reason martyred by fanaticism; novels and films made her a tragic heroine. What she actually calculated has received rather less attention.

The question that remainsWhen someone is recorded as strange — are we reading the person, or the age that recorded them?
