Axiothea of Phlius (4th c. BCE) was one of the two women admitted to Plato's Academy — she came from the Peloponnese after reading the Republic, allegedly traveling to Athens disguised as a man to study. Continued her studies under Speusippus.
Among the earliest documented female philosophy students.
Axiothea does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Axiothea reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
