Hypnos

Hypnos (Ancient Greek Ὕπνος) is the divine personification of peaceful sleep, the restorative rest of the mind, and the soothing release from physical toil in Classical Greek mythology. A primeval offspring born of Nyx (Night) without male intervention, he is the twin brother of Thanatos (inescapable Death). While his brother embodies the sudden and permanent severance of the vital breath, Hypnos is portrayed in Hesiodic and Homeric verse as a gentle, sweet, and benevolent power who moves silently across the inhabited earth and the vast expanse of the sea to pour the balm of quietude over all living beings. His divine authority was universal and extended above the Olympian hierarchy itself: in the famous 'Deception of Zeus' (Dios Apate) episode in Book XIV of the Iliad, Hera seeks out Hypnos on the island of Lemnos, reverently addressing him as 'lord of all gods and sovereign over all mortals,' persuading him with the promise of marriage to the youthful Grace Pasithea to close the eyes of the king of the gods upon Mount Ida while Greek forces turned back the Trojan assault. Alongside his twin Thanatos, Hypnos undertakes a duty of profound honor in Book XVI of the same epic: receiving the anointed corpse of Sarpedon, king of Lycia and beloved mortal son of Zeus slain in combat, the two winged brothers bear the hero through the sky to his ancestral land for monumental burial rites.
