Hypnos

Hypnos is the son of Nyx (Night), born with no father, and the twin brother of Thanatos, Death. Homer's Iliad shows him twice: once carrying the body of Zeus's son Sarpedon home to Lycia alongside his twin, and once being bribed by Hera into lulling Zeus to sleep, a favor he agrees to only after she swears to give him one of the Graces as a wife.

Core Myth

Hesiod's Theogony names Hypnos among the children Night bore without any father, alongside his twin brother Thanatos, Death. Homer's Iliad gives him his clearest role in action: when Zeus's son Sarpedon falls at Troy, Zeus orders Apollo to clean and anoint the body and hand it over to Sleep and Death, the twin brothers, to carry swiftly home to the wide land of Lycia for burial - the two personifications working together exactly as their shared birth suggests they should. The Iliad also tells a longer, stranger story about Hypnos and Hera. Wanting Zeus asleep so she can intervene unseen in the war below, Hera asks Hypnos directly for his help, offering a golden throne forged by Hephaestus. Hypnos refuses at first, recalling the one other time he agreed to something like this: putting Zeus to sleep so Hera could move against Heracles at sea, a favor that ended with Zeus in a fury Hypnos escaped only by fleeing to his mother, Night, whose protection Zeus respected enough to hold back his anger. Hera secures his help this second time only by swearing a binding oath to give him Pasithea, one of the younger Graces, as a wife - the one he says he has longed for all his days.

Who are Hypnos's parents, and does he have siblings?

Hesiod names Night as his mother, with no father given at all - Hypnos is one of the children she bore entirely on her own. His twin brother is Thanatos, Death, and the Theogony lists the two of them together in the same breath as her other, similarly stark children.

Hesiod, Theogony 211-213

What did Hypnos and his twin brother do for Sarpedon?

After Sarpedon, a son of Zeus, was killed at Troy, Zeus ordered Apollo to prepare the body and hand it to Sleep and Death, the twin brothers, who carried it swiftly to Sarpedon's homeland of Lycia so he could be buried properly among his own people rather than left on the battlefield.

Homer, Iliad 16.671-683

Why did Hypnos initially refuse to help Hera put Zeus to sleep?

He had done exactly this once before, lulling Zeus to sleep so Hera could act against Heracles at sea, and it very nearly cost him everything: Zeus's fury on waking was so total that Hypnos survived only by fleeing to his mother, Night, whose protection Zeus respected enough to hold his anger back. He was not willing to risk that twice without real assurance.

Homer, Iliad 14.249-262

What did Hera actually give Hypnos in exchange for his help?

She first offered a golden throne forged by Hephaestus, but Hypnos held out for something he wanted more: a binding oath that she would give him Pasithea, one of the younger Graces, as a wife - a match he says he has desired all his days. Only after she swore that oath did he agree to lull Zeus to sleep.

Homer, Iliad 14.225-262

Where does Hypnos live?

Hesiod places his dwelling in the same remote region as his mother Night, near where the Titan Atlas stands bearing up the sky and close by the gates of Tartarus - ground the shining Sun is said never to look upon as he crosses the heaven in either direction.

Hesiod, Theogony 744-761

Later Traditions

Hesiod places Sleep's dwelling in the same remote region as his mother Night, near where Atlas stands bearing the sky and close by the gates of Tartarus - a place, Hesiod says, that the shining Sun never looks upon as he crosses the heaven, whether rising or setting.
