In Greek mythology the river Styx is the boundary between the land of the living and the land of the dead, Hades.
Because the NT uses a name from Greek mythology (Hades) I wonder some there are some implied parallels.
For example when the Israelites(dead) crossed the Jordan(Styx) they entered the promised land (exited Hades)
==> If we picture the promised land a life then everything outside of it is death/hades.
Rich man and Lazarus also had a "gulf fixed"
==> Was Lazarus in Israel and rich man in hades and it was the river Jordan/Styx separating them?
