King Gilgamesh of Uruk left his throne to seek eternal life after his friend Enkidu died, but lost the plant of youth to a snake and accepted human mortality — the theme of the Epic of Gilgamesh, humanity's oldest story.
Ancient Athens filled most offices — the Council of 500, magistracies, and juries — by lottery (sortition) using the kleroterion, not by election, to stop the powerful few from seizing power.
Ancient Athens let citizens vote once a year to exile any man whose power grew dangerous — writing his name on a shard of broken pottery (an ostracon). Passing the count meant ten years' exile. This was ostracism, a check against tyranny, not a punishment.
As a boy of about nine, Hannibal is said to have sworn at an altar never to be a friend to Rome — an oath his father Hamilcar Barca set in him after Carthage's defeat in the First Punic War, told by the historian Polybius.
Why did Hannibal lead war elephants over the Alps? The sea was Rome's, so Carthage's general took the road no one expected — and trapped Rome at Cannae.
At Cannae (216 BC), the outnumbered Hannibal drew Rome's larger army into a double envelopment and turned its numbers into a trap — still taught in military academies 2,200 years later.
In 196 BC the Rosetta Stone recorded a decree honoring Ptolemy V in three scripts — hieroglyphs, Demotic, and Greek. Found in 1799, its readable Greek let Champollion decipher Egyptian hieroglyphs around 1822, reviving a dead script.
In 1922 Howard Carter peered by candlelight through a sealed door in Egypt's Valley of the Kings and said 'wonderful things' — the discovery of Tutankhamun's tomb, the only nearly-intact pharaoh's tomb ever found.
