Thanatos

Thanatos (Ancient Greek Θάνατος) is the primeval divine personification of inevitable death and the final cessation of mortal life in Classical Greece. Brought forth by Nyx (Night) parthenogenetically at the threshold of cosmic creation, he is the twin brother of Hypnos (Sleep). While his brother embodies the temporary, restorative rest that soothes human suffering, Thanatos represents the irrevocable severing of the vital breath: as depicted with grim solemnity in Hesiod's Theogony, he possesses an 'iron heart and bronze entrails within,' holding fast anyone seized in his grasp and despised even by the immortal gods of Olympus. In ancient religious thought and poetry, Thanatos was not the deity of butchery or battlefield massacre — a bloody domain assigned to the ferocious Keres —, but rather the sovereign and peaceful arrival of life's biological end that frees the soul (psyche) from the physical body. In Attic drama, his portrayal reaches its theatrical height in Euripides's Alcestis: appearing cloaked in black and wielding an iron sword to sever a sacred lock of hair from the dying queen, Thanatos defends the universal ordinance that all mortals must render their allotted debt, only to be ambushed and physically wrestled into submission by Heracles beside the royal tomb. Alongside Hypnos, he performs the noble heroic task recorded in Book XVI of the Iliad, carrying the purified body of Sarpedon from the plains of Troy to Lycia for monumental funeral rites.
