The act of jumping from height into water has had a fairly significant cultural role in other civilisations around the world throughout history. One striking example comes all the way from eighteenth century Hawaii.
In 1770, the island of Maui’s last independent ruler, King Kahekili leapt from a towering 63ft cliff known as “Pu’u Keka’a” (don’t ask us how to pronounce that, apparently it’s more commonly known as Black Rock nowadays) into the waters of Kaunolu Bay. After this feat he was then referred to as “The Birdman” and insisted that his warriors repeated the jump as a display of courage and loyalty!
If jumping from almost 20 metres was the way to show loyalty, what was the punishment for not jumping? It’s probably best not to think about it.
