I knew about both the Fibonacci sequence and transfinite numbers in elementary school. Granted, I was above average, but I was no prodigy.
Anyway, it is trivial to map the Fibonacci sequence into a single number. Just make an infinite list of Fibonacci numbers, and concatenate the digits into one infinite string, with a single “A” inserted between each pair numbers. Then treat that as a single hexadecimal number. (Or a mere base-11 will do, actually.) If you do this, and calculate π, as well, you will find that both strings have a length of א-null, so the lengths are equal. Easy-peasy.
Well, it is certainly true that it took me a lot of effort to learn to sing Johann Strauss’s pig-farmer song in German with a thick, “hayseed” Hungarian accent.
Actually, people at the time already believed the story about lemmings, and had for generations. The Disney people did force the lemmings that they were filming to go over a (fake) cliff, but they thought that something—they didn’t know what—was spooking the lemmings, stopping them from doing what they would normally do, and they obviously needed the shot.

Fountain pens had not been invented in the era of King Saul, but I know they existed by the time of King Gustav III of Sweden.
