Lemuria is the name of a hypothetical "lost land" variously located in the Indian and Pacific Oceans. It is said in Tamil legend to have been civilised for over 20,000 years, with its population speaking Tamil.
"Lemuria" entered the lexicon of the occult through the works of Helena Blavatsky, who claimed that the Mahatmas had shown her an ancient, pre-Atlantean Book of Dzyan.
Within Blavatsky's complex cosmology, which includes seven "Root Races", the "Third Root Race" occupied Lemuria. She describes them as about 7 feet (2.1 m) tall, sexually hermaphroditic, egg-laying, mentally undeveloped and spiritually more pure than the following "Root Races". Before the coming of the Lemurians, the second "Root Race" is said to have dwelled in Hyperborea.
James Bramwell portrayed Lemuria in his book, Lost Atlantis, as "a continent that occupied a large part of what is now the South Pacific Ocean". According to Bramwell, Lemurians are the ancestors of the Atlanteans, who survived the period "of the general racial decadence which affected the Lemurians in the last stages of their evolution". From "a select division of" the Atlanteans – after their promotion to decadence – Bramwell claims the Aryan race arose. "Lemurians, Atlanteans, and Aryans are root-races of humanity", according to Bramwell.
