She was the daughter of Theon, a mathematician who taught at the great school at the Alexandrine Library. She traveled widely and corresponded with people all over the Mediterranean. We know of her only through her letters because all of her work was destroyed when the Great Library of Alexandia was destroyed. She taught at the school in the Library in Alexandria, Egypt. Letters written and addressed simply to the philosopher were delivered to her. She taught mathematics and natural philosophy.
She died violently. She was dragged to her death by a mob who pulled her from her classroom into the streets where they peeled her to death with oyster shells.
She wrote that
All formal dogmatic religions are fallacious and must never be accepted by self-respecting persons as final.
Fables should be taught as fables, myths as myths, and miracles as poetic fancies.
To teach superstitions as truths is a most terrible thing.
The child mind accepts and believes them, and only through great pain and perhaps tragedy
can he be in after years relieved of them.
In fact men will fight for a superstition quite as quickly as for a living truth
often more so, since a superstition is so intangible you cannot get at it to refute it,
but truth is a point of view, and so is changeable.
