Elysium:

 

Greek Elysian Fields

In Greek mythology, Elysium was a section of the Underworld (the spelling Elysium is a Latinization of the Greek word Elysion). "Elysium is an obscure and mysterious name that evolved from a designation of a place or person struck by lightning, enelysion, enelysios. (Burkert 1985 p. 198)

The Elysian fields were the final resting place of the souls of the heroic virtuous. Two passages in Homer established for Greeks the nature of the Afterlife: the dreamed apparition of the dead Patroclus in the Iliad and the more daring boundary-breaking visit in Odyssey. Greek traditions concerning funerary ritual were reticent, but the Homeric examples encouraged other heroic visits, in the myth cycles accreted upon Theseus and upon Heracles (Campbell 1948; Ruck and Staples 1994)

The Elysian Fields lay on the western margin of the earth, by the encircling stream of Oceanus (Odyssey), and there the mortal relatives of the king of the gods were transported, without tasting death, to enjoy an immortality of bliss (Odyssey book iv: 563). Hesiod refers to the Isles of the Blessed (makarôn nêsoi) in the Western Ocean (Works and Days). Pindar makes it a single Isle. Walter Burkert notes the connection with the motif of far-off Dilmun: "Thus Achilles is transported to the White Isle and becomes the Ruler of the Black Sea, and Diomedes becomes the divine lord of an Adriatic island." (Burkert 1985, p. 198).
