“[It was 1619.] A strange ship, indeed, by all accounts, a frightening ship, a ship of mystery [rode the tide in from the sea, sails unfurled, flag drooping at her rounded stern.] Her port of call, an English settlement, Jamestown, in the colony of Virginia. She came, she traded, and shortly afterwards was gone. Probably no ship in modern history has carried a more portentous freight. Her cargo? Twenty slaves.”
