Lemuria was a name invented in 1864 by the English zoologist Philip Lutley Sclater (1829-1913) to describe a hypothetical landmass in the Indian Ocean that was used to explain the isolation of lemurs on Madagascar while related fossils were spread across Africa and South-East Asia.The name has also been credited to the English geologist, William Thomas Blanford (1832-1905). It is further claimed that Ernst Heinrich Haeckel (1834-1919), the German professor of zoology and ardent supporter of Darwin, had made a similar suggestion regarding a sunken continent before Sclater without attributing a particular name to it.
Mu on the other hand is the name given to a fictional continent that was supposed to have existed in the Mid-to-Southern Pacific Ocean and given popular recognition by the writings of James Churchward who promoted it as the Atlantis of the Pacific. However, many writers continue to use the two words interchangeably. Frank Joseph links the destruction of ‘Lemuria’ with the Plagues of Egypt[106][107].
Madame Blavatsky claimed Lemuria as a pre-Atlantis source of Ancient Wisdom. She ‘revealed’ that the Lemurians had four armed egg-laying hermaphrodites with a third eye. Unfortunately, Blavatsky’s esoteric bosh is still touted widely today in books and the Internet(a).
