If asked what country first minted coinage with the image of the Christian cross on it, most would answer Rome or some place in Europe. Other more scholarly people would say Antioch or the holy lands. But, the fact is, the first coin to bear the image of the Cross was minted in Ethiopia!
As stated before, the country of Ethiopia was ruled by a long line of kings who claimed to be descended from the son of the Queen of Sheba and King Solomon. This Solomonic dynasty reigned off and on for most of antiquity. Once such King, Bozan, was said to be the Balthazar of the Nativity.
