Short answer: Thanatos is the Greek god of death itself: the moment, not the place. Son of Nyx, the Night, and twin brother of Hypnos, Sleep. He arrives when your thread is cut, touches you, and carries you away. Hades only rules what happens afterwards.
Death's job description
| Figure | Role | Common mistake |
|---|---|---|
| Thanatos | Death itself, the arrival | Confused with Hades constantly |
| Hades | King of the dead, the destination | He never comes to fetch you |
| Charon | The transport between | Has his own post |
| The Keres | Violent death on battlefields | The dark counterpart to gentle Thanatos |
The Greeks split death into specialists. Thanatos was the gentle version: winged, quiet, often shown as a beautiful young man with a lowered torch. His sisters the Keres handled the screaming kind.
The man who chained Death
Sisyphus, king of Corinth, knew Thanatos was coming for him. So he asked, innocently, how the god's own handcuffs worked... and clicked them shut on Death himself. For days, nobody on Earth could die. Soldiers were run through and stood back up. It took the god of war, Ares, personally furious that battles had stopped being lethal, to free Death and hand Sisyphus over. The boulder came later, and that story is its own episode.
Twin of Sleep
Homer calls Sleep and Death twin brothers, and the Iliad shows them working together: they carry the fallen hero Sarpedon home to Lycia, gently, one on each side. The Greeks put the two experiences side by side on purpose: every night you rehearse with one twin, until the day the other one comes.
Quick questions
Is Thanatos evil?
No. He is implacable but fair: he comes for everyone once and takes no pleasure in it. Greek poets reserve horror for the Keres and pity for Thanatos; there is a difference between death and violence.
Why is the Marvel villain called Thanos?
The name is clipped from Thanatos, and the borrow is on theme: a character obsessed with death, named after Death. The Greeks would have appreciated the branding.
Where does Thanatos live?
In the underworld with his mother Night, in most tellings near the gates. His workplace is everywhere else.
