Hypnos in Greek tradition
Sleep brings Hypnos close to his twin brother Thanatos, yet the Greeks welcomed one and feared the other. Hypnos is the deity of sleep, dreams, nighttime repose, and relief from cares and woes. He is shown with closed eyes, a poppy stalk, wings, or a sleep-bringing horn, and dwells in a silent cave beyond the sun’s reach. Unlike Thanatos, the personification of death, Hypnos offers mortals a kind and beneficent rest.

The myths of Hypnos
2 myths, each traced to its primary text and corpus sources.
The Birth of Hypnos
Nyx gave birth to Hypnos and his twin brother Thanatos without a father. Nyx was the daughter of Chaos and the personification of Night. She was associated with mysterious and inexplicable things, including death, sleep and dreams. Through her, Sleep and Death entered the divine family of Night.
Hypnos and Thanatos dwelt in the realm of shades. When they appeared among mortals, they produced different effects. Thanatos, whose name meant Death, was feared and hated as the enemy of mankind. His hard heart showed no pity. Hypnos, whose name meant Sleep, was welcomed and loved by everyone.
Nyx inhabited a palace in the dark regions of the lower world. She travelled through the darkness in a chariot drawn by two black horses, while stars followed her. She wore dark robes and a long veil. Her presence connected the darkness of the lower world with the sleep, dreams and death that came from her.
In another telling, Nyx became united with Erebus, who was Darkness. Their children were Aether and Hemera, who were Air and Daylight. This union placed darkness before light. The birth of Hypnos and Thanatos placed sleep and death among Nyx's offspring. Hypnos then brought the welcome of sleep to mortals, while Thanatos brought the fear and hatred attached to death.

“Night bore Sleep and Death without a father, among her other dark offspring.”
Hesiod, Theogony
Hypnos and Pasithea
Hera approached Hypnos and offered him one of the Graces as a bride. She wanted his help in keeping Zeus out of action long enough for the fighting in the Trojan War to favour the Greeks. Hypnos accepted the bargain. The Grace promised to him was Pasithea, whom he desired and later married.
Hypnos was the Greek god and personification of Sleep. Hesiod described him as a child of Night, making him one of the oldest gods. He was sometimes shown standing with closed eyes, or lying beside his brother Thanatos, the personification of Death. He usually carried a poppy stalk.
His dwelling was a mountain cave near the land of the Cimmerians. The sun never reached it. No song, voice, or other sound disturbed the silence. The river Lethe flowed from the lowest rocks, making a quiet, unchanging noise. White and red poppies hid part of the entrance. Mother Night gathered and planted them, then drew drowsiness from their juice and scattered it over the earth in liquid drops.
Pasithea became the mother of the dream spirits associated with Hypnos. Ovid said that Hypnos had a thousand sons, including Morpheus. Morpheus took human form in dreams and imitated people’s speech, movements, and gestures. Phobetor, also called Icelos, appeared as animals. Phantasos assumed the forms of lifeless things, such as rocks, trees, and water. These spirits belonged to the company of dream beings linked with Hypnos and Pasithea.
