Short answer: you quote Greek mythology every day without noticing. When you call something an Achilles' heel, open a Pandora's box, or follow Ariadne's thread out of a mess, you are using stories roughly three thousand years old. Here are the fourteen that survived, and what the originals actually said.
The 14 expressions
| Expression | What it means today | The myth behind it |
|---|---|---|
| Achilles' heel | The one fatal weakness | His mother dipped him in the Styx holding him by the heel, the only spot the water missed |
| Pandora's box | A decision you cannot take back | It was a jar, and she was not curious by accident: the gods built her as a delivery system |
| The Midas touch | A talent for turning anything into money | Midas asked for it, then could not eat, drink, or touch his daughter |
| Siren song | A beautiful temptation that kills | The Sirens sang from a beach covered in bones. Your emergency siren is named after them |
| Herculean task | A job so big it looks impossible | Twelve labours imposed as penance after he killed his own family in a divine rage |
| Apple of discord | The small thing that starts a huge fight | Eris rolled a golden apple marked "to the fairest" into a wedding, and the Trojan War followed |
| Ariadne's thread | The way out of a maze of a problem | She handed Theseus a ball of yarn so he could find his way back out of the labyrinth |
| Sword of Damocles | A permanent, suspended catastrophe | A courtier envied the throne, so the king sat him on it under a blade hung by one horsehair |
| Trojan horse | An attack disguised as a gift | The Greeks left a wooden horse packed with soldiers and pretended to sail home |
| Between Scylla and Charybdis | Between a rock and a hard place | A six headed monster on one cliff, a whirlpool on the other, and a strait too narrow to dodge both |
| Oedipus complex | Freud's name for rivalry with a parent | He killed his father and married his mother without knowing either fact until it was too late |
| Flying too close to the sun | Ambition that destroys the ambitious | Icarus ignored his father's altitude instructions, the wax melted, the wings came apart |
| Narcissist | Someone in love with their own image | He fell for his reflection. Echo, who loved him, could only repeat his last words back |
| Procrustean bed | Forcing reality into a rigid rule | Procrustes offered travellers a bed, then stretched or amputated them until they fit it |
One more: Promethean means daring, inventive, and punished for it. Prometheus stole fire for humans and got an eagle at his liver, daily, forever.
The one everybody gets wrong
Pandora's box was a jar, a pithos, the tall clay storage vessel Greeks buried in the ground. The "box" is a Renaissance mistranslation that stuck. And the ending is stranger than the version people repeat: when she closed the lid, everything harmful had already flown out. The only thing still inside was hope.
Is hope a comfort we keep, or the one evil the gods held back, since expecting things to improve is what keeps humans grinding? Hesiod closes the lid without saying.
Quick questions
What was really inside Pandora's box?
Every affliction: illness, hard labour, old age, grief. All of it escaped the moment the lid lifted, and hope stayed sealed under the rim. Note that Pandora was the punishment, not the criminal: Zeus built her as revenge for accepting stolen fire.
Was Achilles really invulnerable except for his heel?
Not in Homer. In the Iliad he bleeds like anyone else and simply fights better. The Styx dip and the fatal heel arrive centuries later, in Roman era poets like Statius. The great duel of the Iliad works precisely because Achilles is mortal and knows it.
What is a Trojan horse in computing?
The name is literal. A trojan is software you install yourself because it looks useful, and the attack is already inside. Same trick, same result: the walls held, the gate opened from within. Shelve it with the other objects that ruined their owners.
Want the full versions, not the one line summaries? MythologyNow narrates them like films. Start with Minos, Pasiphae and the Minotaur, the myth that gave us both Ariadne's thread and Icarus.
