Ethiopian eunuch
the chief officer or prime minister of state of Candace (q.v.), queen of Ethiopia. He was converted to Christianity through the instrumentality of Philip (Act 8:27). The northern portion of Ethiopia formed the kingdom of Meroe, which for a long period was ruled over by queens, and it was probably from this kingdom that the eunuch came.
