At

Found in cultures around the world where traditions of Atlantis-like experiences
have been preserved in folk memory, and usually denoting a sacred mountain
(from the Mount Atlas of Atlantis), often volcanic and sometimes symbolized by a
holy altar, such as the Samoan Atua. Throughout the prehistoric New World of the
Americas, At invariably defines an eastern location (Aztlan, etc.), while, in Old World
traditions, it is associated with western places (Atum, etc.)—appropriately enough,
because mid-ocean culture-bearers sailed from Atlantis to both east and west. As
such, in numerous cultures around the world, At is a prefix, a word, or a name in
itself, defining a sacred mountain associated with ancestral origins, commonly after
a world-class deluge.
