The Oracles were Temples or holy places situated in various regions of Atlantis. There was one Manu for each of the seven planetary oracles and one oracle for each kingdom. The Oracle of the Sun took its abode in the kingdom leading an age.
From these oracles was communicated all religion, science and art to its peoples.
Out of all the Oracles the Sun Oracle was the highest and most venerated and its Manu the most evolved. The Vulcan Oracle which stood beside it was the most dangerous and therefore the most hidden.
