The Berbers were a nomadic tribe from the northern  coast of Africa who had come under Roman rule.

柏柏尔人是来自非洲北海岸的一个游牧部落，曾受罗马统治。

Right, so anyway the Berbers were early converts to Islam, and Islam spread along those pre-existing trade routes between North and West Africa.

是的，所以不管怎样，柏柏尔人很早就皈依了伊斯兰教，伊斯兰教沿着北非和西非之间那些先前存在的贸易路线传播。

It was rare for a non-Roman to achieve such  high status in the Roman army, and it is possible Quietus had royal standing amongst  the Berbers alongside his Roman citizenship.

非罗马人在罗马军队中获得如此高的地位是很少见的，而且奎图斯有可能在柏柏尔人中与他的罗马公民身份一样拥有王室地位。
