Original sense
Lemuria is the continental system of the Third Root-Race, stretching through what is now the Indian and Pacific oceans. Early Lemurians, in her account, are not yet fully physical, sexual, or linguistic as we are; later ones become the first truly human type. The Easter Island statues, she speculated, remember their giants.
Lemuria is the name given to the continent of the Third Race… a land that stretched from the Indian Ocean to the Pacific.
She took a discarded biological hypothesis and made it a chapter of occult anthropology. The gentle, psychic, matriarchal Lemuria of later lore is mostly a twentieth-century overlay (Churchward’s Mu, then Mount Shasta mythology).
