Lemuria

Lemuria is the name of a proposed lost continent, held to have been situated in either the Indian or Pacific Ocean, formerly referenced as a hypothetical land bridge to explain fossil records during the mid-nineteenth century, and refigured by the Theosophical Society and other orders in later years as a bygone home to a "root-race" of ancestors to modern humans.

Land Bridge

 * The term "Lemuria" was coined by P. L. Sclater in 1864 to refer to a hypothetical continent that would have formerly connected India and Madagascar.

Theosophical Society

 * In her 1888 book "The Secret Doctrine," the Theosophist H. P. Blavatsky advanced a theory that Lemuria was the ancient forerunner of the current continents, ultimately sunk beneath the ocean some seven hundred thousand years ago, the aftermath of which saw new continents formed, including Atlantis; and that Lemuria was the home of the "Third Root-Race."

"A Dweller on Two Planets"

 * 1894
