Thanatos

Thanatos was the personification for peaceful death and the twin brother of Hypnos (sleep) - unlike their several siblings, who represent painful/violent death. He is the son of Nyx and Erebus.

Description and Attributes
Thanatos is often seen as a bearded, winged, man and sometimes as a winged youth, with flowers. He is rarely seen without his twin, Hypnos - the God of Sleep. The two are associated with peaceful death as opposed to the Moros, Keres, etc.

According to myth if Thanatos cut your hair with his sword, you will die. His symbols are a sword, an upside down torch (representing the end of life), and a butterfly. ψυχή ( psyche), the Greek word for butterfly, can also mean soul, or life.

Birth
Thanatos was born to Nyx and Erebos. As well as his twin brother is Hypnos, the god of slumber. He has two sisters, the Keres sisters.

Sarpedon
During the Trojan War, Thanatos and his brother, Hypnos, carried the dead body of Sarpedon off the battlefield to his homeland to be given a proper burial.

Sisyphus
Sisyphus often killed guests and travelers, which violated certain laws the gods put into place. He also had children with his niece, had stolen his own brothers right to the throne, and betrayed Zeus. Because of this, Zeus ordered Thanatos to throw him into Tartarus. Thanatos was tricked by Sisyphus, however, when Sisyphus asked Thanatos to show him how the chains worked. Thanatos showed him, and Sisyphus sealed him in Tartarus. Days passed, and no human or monster would die. Ares soon found out the problem, and released Thanatos.

Alcestis
Alcestis and Admetus were getting married. On the night of the marriage, Admetus was drunk and forgot to give his sacrifice to Artemis. She was angered, and filled his bed with snakes, killing him. However, Apollo, who had to serve him for one year, got the Fates drunk and saved him. However, someone now had to take his place. Because nobody else stepped forward, Alcestis, being the loyal and loving wife she was, came forward and sacrificed herself. Days later, Heracles attended her funeral, and found himself to be enjoying it. Somewhat angered by this, he went down to Hades and fought Thanatos. He won, and took Alcestis with him. Thanatos was angered by this, but felt Heracles won fairly and let him live.

Family and Consorts
Thanatos' lineage includes: Nyx, Erebus (in some myths), Ares, Eris, Charon, Hypnos, Momos, and the like. It is unknown who his consort is- as he his a lesser known god- though in some myths his partner is Makaria - daughter of Hades in some myths, representing a blessed death.
