Mandaeans are a religious grouping that in recent years was centred in Iraq until the war there dispersed them across the world, leaving just a few thousands in their original homeland. Efforts to resettle them as a single group have failed, putting the continued existence of this religious minority seriously at risk.
Their place in this work is mainly due to the views of the prolific Italian writer, Mario Pincherle, who has advocated the radical view that the Mandaeans are the last remnants of the Atlanteans. One website(a) goes even further suggesting that the Mandaeans have some knowledge of the secret behind the UFO mystery. A more recent article studies this in greater depth(b).
