There exist many clues from paintings, letters, and even engravings in the walls of the Tower of London that challenge the orthodox history of the Tudor Dynasty. This evidence reveals that Queen Elizabeth the First had two children: Sir Francis Bacon (on left) and Robert Devereux (on right who became known as the Earl of Essex). The boys were adopted by different families, but each eventually discovered their true heritage. The Earl of Essex led a rebellion and was executed in the Tower. Francis Bacon wrote a history of his maternal grandfather, Henry VIII; there is a Shakespeare play on the same theme. The Tudor emblem of the white rose recurs throughout Bacon's published works.
Robert Dudley, Earl of Leicester (on right), the real father, bears a resemblance to both Francis Bacon (on left) and his brother Essex.
