    <dc:creator>hex</dc:creator><description><![CDATA["Labyrinths are part of a universal symbolic language. Joseph Campbell claimed that it takes many thousands of years for a myth to change [1]. However, it would appear that it takes twice as long for the essential structure of a symbol to change, if at all. Some labyrinths, complex and difficult geometry structures, have been used for many thousands of years completely unchanged in their structure. However, these structures can became embedded into other cultures. While the format of the symbol can change the underlining structure remains untouched. 

"By examining the geometry of these formats that contain these structures it is possible to track connections in cultural transferences, philosophy, myths, religions and ritual. The purpose of this paper is to construct a topology that will assist in looking for these connection and transferences. In this way geometry can assist in revealing connections in the history of ideas behind the use of symbol."]]></description>
