Mithras

Many people do not know that there are a few versions of Mithras.  There was Roman, Zoroastrian, Greek, Iranian, Hindu, Persian and Sabean versions of Mithras.  They were all blended together and composed to local ways to become the one that Rome eventually adopted.  Of course Rome added and deleted things to make Mithras their version.  The Mithras cult is very old indeed.  In most to the Mithras reliefs he is slaying a bull.  Most researchers have no idea why he is slaying a bull.  It all has to do with the sun in the age of Taurus.  Slaying the bull meant the sun was about to exit Taurus, so Mithras had slayed the bull.
