Dear Bernard on reading the books of Arthur there where many mentions of the religious roman cult of Mithras. The name rang a bell from a book i read some years ago by Micheal Curtis Ford called the last king.It states in the first century BC. Mithridates the great was the last king of Pontus and Romes greatest ever enemy more so even than Hannibal.Did the cult of Mithras arise from this historical figure as he lived some six centuries before Arthur’s time or do i again have my head in the clouds. kind regards Nicholas Horton.
