David Rhys Williams wrote about what theory that Marlowe was the author of Shakespeare plays?
Marlovian theory of Shakespeare authorship The Marlovian theory of Shakespeare authorship holds that the Elizabethan poet and playwright Christopher Marlowe was the main author of the poems and plays attributed to William Shakespeare. Rather, the theory says Marlowe did not die in Deptford on 30 May 1593, as the historical records state, but that his death was faked.
Double Falsehood Double Falsehood (archaic spelling: Double Falshood) or The Distrest Lovers is an early 18th-century play by the English writer and playwright Lewis Theobald, although the authorship has been contested ever since the play was first published, with some scholars considering that it may have been written by John Fletcher and William Shakespeare. Some authors believe that it may be an adaptation of a lost play by William Shakespeare and John Fletcher known as "Cardenio". Theobald himself claimed his version was based on three manuscripts of an unnamed lost play by Shakespeare.
