It is unclear if King Solomon was black. There are no pictures showing his skin color, but many disagree on whether or not he was black.
Many believe that King Solomon speaks, "I am black, but comely, O ye daughters of Jerusalem, as the tents of Kedar, as the curtains of Solomon and "Look not upon me because I am black, because the sun hath looked upon me. My mother’s children were angry with me; they made me the keeper of the vineyards, but mine own vineyard have I not kept," in the poem Song of Solomon found in Song of Solomon 1:5-6. Others say it is his lover speaking.
According to ancient Hebrew, the word black, is defined in "The New Strong's Exhaustive Concordance of the Bible" as dusky. Dusky is defined in a dictionary to mean dark skinned, but not necessarily black. Despite this explanation many still interpret the Bible as saying he is black. To further confuse things King Solomon is depicted as black in some films and documentaries and light skinned in others.
Consider checking out a Hollywood depiction of King Solomon in Solomon and Sheba (1959) starring Yule Brenner (Solomon) and Gina Lollobrigida (Sheba).
Of interest, according to a recent Gallup Poll, 28% of Americans believe that the Bible was the "actual word of God." The percentage is down from 38% to 40% in the late 1970s. Find out more from the Huffington Post.
