LONDON, ENGLAND - MAY 19: A copy of The Herball book shows what is thought to be the first authenticated living portrait of William Shakespeare at The Rose Theatre on May 19, 2015 in London, England. Botanist and historian Mark Griffiths has revealed he has cracked a many-layered Tudor code and revealed the living face of Shakespeare for the first time, on the title page of the first edition of The Herball, a 16th century book on plants, 400 years after it was first published.
