A death mask thought to be that of English dramatist William Shakespeare (1566–1616). Found by Dr. Ludwig Becker in Mainz in 1849, the mask was linked to Shakespeare because of its 1616 date and its supposed facial resemblance to the writer. A rival theory, however, maintains that the mask is more likely to be that of English poet Ben Johnson. (Photo by Hulton Archive/Getty Images). Circa 1900
