There’s nothing like a good riddle to twist your brain into knots and to provide a satisfying zing when you solve it correctly. Riddles can offer entertainment and fun while also giving your brain something genuinely hard to work on. As it turns out, these enigmatic, often extremely frustrating (yet shockingly obvious when you know the answer!) questions have actually been confounding humans for thousands of years.

Famous Riddles in History

Riddles have a very long history. In many myths, heroes encounter ancient beasts or guardians who force them to answer tricky questions in order to pass. This is the case for the Greek tragic hero Oedipus, who famously defeats the winged Sphinx by solving her riddle, and thus saves his own life—for the time being.

In some versions of the story, the question she asks is: “What goes on four feet in the morning, two feet in midday, and three feet in the evening?” Oedipus ultimately provides the correct answer, which is: “Man.” Upon being bested, the Sphinx throws herself to her death.

Another millennia-old reference to riddles appears in the biblical story of Samson. In this tale, Samson shares a riddle with his Philistine companions at his wedding celebration and promises to give them clothes if they succeed. The puzzle he poses is as follows: “Out of the eater came something to eat; out of the strong came something sweet.”

The men eventually coerce Samson’s bride into telling them the answer: “What is sweeter than honey, and what is stronger than a lion?” Samson’s riddle references a time when he killed a lion, then returned to find that a swarm of bees had produced honey in its carcass, which he then served to his unwitting parents.

Fortunately, if you’re reading this, you aren’t facing the threat of death at the hands of a monstrous, self-destructive hybrid creature. You likely aren’t a desperate wedding guest, either (though that is slightly more in the realm of possibility), or someone who has eaten honey out of a dead lion.

Instead, these riddles are perfect for testing your mental fortitude or confounding your friends and family at your next social gathering. Still, it might raise the stakes a bit to imagine that you’re standing before an imposing mythical monster while reading these quandaries. Some of these might also make you think of the world in entirely new ways. How swiftly can you solve these tricky riddles?
