For hundreds of years, people have questioned whether William Shakespeare wrote the plays that bear his name. The mystery is fueled by the fact that his biography simply doesn’t match the areas of knowledge and skill demonstrated in the plays. Nearly a hundred candidates have been suggested, but none of them fit much better. Now a new candidate named Amelia Bassano Lanier – the so-called ‘Dark Lady’ of the Sonnets and a member of an Italian/Jewish family – has been shown to be a perfect fit.
Via the Shakespeare Geek, who is kind enough to suspect that the whole thing is a put on.
