The race of Cleopatra VII, the last active Hellenistic ruler of the Macedonian-led Ptolemaic Kingdom of Egypt, has caused some debate in some circles. Scholars have concluded that she was largely of Macedonian Greek ancestry (with some Persian), but others have wondered whether she had additional ancestries. For example, the article "Was Cleopatra Black?" was published in Ebony magazine in 2002. Mary Lefkowitz, Professor Emerita of Classical Studies at Wellesley College, traces the main origins of the Black Cleopatra claim to the 1946 book by J. A. Rogers called "World's Great Men of Color", although noting that the idea of Cleopatra as black goes back to at least the 19th century. Lefkowitz refutes Rogers' hypothesis, on various scholarly grounds. The black Cleopatra claim was further revived in an essay by afrocentrist John Henrik Clarke, chair of African history at Hunter College, entitled "African Warrior Queens." Lefkowitz notes the essay includes the claim that Cleopatra described herself as black in the New Testament's Book of Acts – when in fact Cleopatra had died more than sixty years before the death of Jesus Christ. Scholars identify Cleopatra as having been essentially of Greek ancestry with some Persian and Sogdian Iranian ancestry, based on the fact that her Macedonian Greek family (the Ptolemaic dynasty) had intermarried with the Seleucid dynasty. Michael Grant states that Cleopatra probably had not a drop of Egyptian blood and that she "would have described herself as Greek." Duane W. Roller notes that "there is absolutely no evidence" that Cleopatra was racially black African as claimed by what he dismisses as generally not "credible scholarly sources." Cleopatra's official coinage (which she would have approved) and the three portrait busts of her considered authentic by scholars (which match her coins) portray Cleopatra as a Greek woman in style. Polo writes that Cleopatra's coinage presents her image with certainty and asserts that the sculpted portrait of the "Berlin Cleopatra" head is confirmed as having a similar profile. Roman frescoes in Pompeii and Herculaneum similar to the Vatican and Berlin marble sculptures have been identified as possible portraits of the queen based on comparable facial features and royal iconography. In 2009, a BBC documentary speculated that Cleopatra might have been part North African. This was based largely on the examination of a headless skeleton of a female child in a 20 BCE tomb in Ephesus (modern Turkey), together with the old notes
