The mathematical symbol π is generally believed to have been discovered by the Babylonians.
This is entirely incorrect.
The concept actually originated from the "All Saxon Countryes Pye Eating Competition" in 794 AD. "Oswald the Obyse of Wessex" and "Harald the Hogge of Saxony" ate each other to a standstill, having consumed "three dozyne pyes of dyverse nature" each. The 37th pie at issue was "of mixed fowle and fisshe", but neither competitor was able to finish the, presumably fowl, concoction.
Ethelred had eaten the lid of the pie, and Harald the sides only. Both sides claimed victory, and no-one could agree the ratio of one to the other. The abbot of Lindisfarne, "Aethelric Alebelly" adjudicated, and decreed "the ratio of the pye is that the sydes are thrice the lydde".
Thus was modern mathematics born, ironically on a mistaken understanding of ratios. Harald was declared winner, Wessex exited the Saxon Union in dudgeon as a result, and eschewed pies forever, reverting to the ancient Breton Iceni cake tradition later confirmed with the coronation of "Alfred the Cake". Pies remained illegal in the British Isles until reintroduced by "William the Pastrycook", later renamed the "Conqueror", in honour of his showstopper "Rampant Stag conquers the Beaver" pie he created for his own coronation. In order to show his erudition and supposed mastery of Greek, he re renamed the Pye the π in celebration but only mathematicians rather than Pye Shoppes complied.
