Source: Kebra Nagast: The Queen of Sheba and Her Only Son Menyelek (Is’haq Neburä -Id of Axum) 1314 A.D. (type in India) (115 and 162)
This source is powerful because it shows a consistent appearance from King David to King Solomon to King Solomon‘s son with Queen Sheba. What does this mean? There was a clear racial continuum from generation to generation. Why is this important? We know Queen Sheba of Axum was most likely a black because she was an Ethiopian. Combining all of this, it is reasonable to suggest King Solomon’s son had some level of black or negroid features.
