Grim Reaper & Origin

12. 
Grim Reaper & Origin
If you're going to give death a human face,
why not make it friendly? That was the ap-
proach taken by the Greeks, who named death
Thanatos.
Thanatos was the twin brother of Hypnos, the
god of sleep, and both were portrayed as
young, pleasant men.
In some illustrations, Thanatos appears with
wings and an extinguished flame. His job was
to accompany the departed to Hades, the
Greek underworld.
There, Thanatos would deliver the souls to
Charon, the ferryman on the River Styx. In this
version, death isn't ugly and frightening, but
attractive and helpful.

and after that, she ferried
the souls of the dead to the
