Mythology & Beliefs: Elysium In Greek and Roman Mythology, Elysium was the abode of blessed dead.
Elysium in Wikipedia
In Greek mythology, Elysium (Greek: Ἠλύσια πεδία) was a
section of the Underworld (the spelling Elysium is a
Latinization of the Greek word Ἠλύσιον Elysion). The Elysian
Fields, or the Elysian Plains, were the final resting places
of the souls of the heroic and the virtuous. Elysium is an
obscure name that evolved from a designation of a place or
person struck by lightning, enelysion, enelysios. This
could be a reference to Zeus, the god of lightning/Jupiter, so
"lightning-struck" could be saying that the person was blessed
(struck) by Zeus (/lightning/fortune). Egyptologist Jan
Assmann has also suggested that Greek Elysion may have instead
been derived from the Egyptian term ialu (older iaru), meaning
"reeds," with specific reference to the "Reed fields"
(Egyptian: sekhet iaru / ialu), a paradisaical land of plenty
where the dead hoped to spend eternity....
