No, their Tribe were not KINGS. They were King Makers, they were hired to conduct Coronation Ceremony's, for all Kingdoms in the mid-east. YES, the MAGI rode Horses, their Tribe Raised Arabian Hours and made a lucrative living, selling those as WAR HORSES to every King in the Mid-East. There is NO CAMELS associated any verse in the BIBLE, with the MAGI. It was a ERROR, based on the imagination of the Scribes, and they rode with no less than Ten Magi, and a 100 of the most skilled Warriors in the land, to protect the TREASURE.
So maybe we have been searching the wrong City for the TRUTH about the MAGI. We need to search the home town of the MAGI, for the first hand writing of the historical account of the MAGI journey to Bethlehem.
That road followed the Silk Road, and has several Watering holes along it. Perhaps this town, NISA. would be a good start of where the writings of the MAGI ended up:
Armenia, Media and the far west of Parthia, and the Gaugemela may have been their Dominant City. If I was to start to search for the Magi History of their Journey, I would start my search for it in or around Gaugemela. It is obvious that they had to have recorded the Journey, and why is nobody trying to search for the Document is Baffling to me.
