The Garden of Eden
There are numerous examples of an idyllic nostalgic past, and Atlantis and Lemuria are just two examples. Another example is in the Book of Genesis when God created the Garden of Eden, an oasis with abundant food and a river. It may have been enclosed as noted in the Song of Solomon 4:12. During the fifteenth and sixteenth centuries, explorers sought the Garden of Eden in the New World; Eden has also been identified in Mesopotamia by the Tigris and the Euphrates rivers, in Syria, or in Golgotha, where Jesus was crucified.
Avalon
Another mythical place that transcends time and place is Avalon, the place where King Arthur was taken to be healed of his wounds after his last Battle of Camlann. Camelot was the capital of the realm of King Arthur and his Knights of the Round Table; it is a timeless land of forests, castles, and magic.
Sumerian Dilmun
Another example is the Sumerian Dilmun, where no illness, grieving, or old age existed.
Hesiod
Greek poets, including Homer, described Elysium, also known as the Elysian Fields, as the end of the world. In his poem Works and Days, Hesiod also describes a Golden Age when people did not grow old or work.
