What is the Oldest Unsolved Math Problem?
evilquaker asks: "After finding a reference to the (still open) odd perfect number problem, which is claimed to date back to Euclid, I wondered: what are the oldest unsolved math problems? The folklore answer is that the odd perfect number problem is the only one posed by the Greeks which is still open. However, it seems there is some doubt as to whether Euclid actually wondered about odd perfect numbers. Further, there's a claim that the twin primes conjecture dates back to the Greeks. So what's the oldest documented still-open math problem? Perhaps something about Fibonacci numbers?"
Do you pronounce "Yohdh" "Yoda" by any chance?

The port of Alaxendria, one of the busiest port-cities, had a law that required ships that came to port to loan all their written scrolls etc. to the library, where it was faithfully copied and archived. That's what made the library (one of) the greatest of its time.
