The mysteries surrounding Shakespeare's authorship of the
canon attributed to him are fascinating but they really should
not be attempted by anyone who is not reasonably well
acquainted with the plays themselves and the literary scene
of the time.
The Baconian heresy seems to have found many adherents
in those who could not bear to think that the National bard
was not a Lord Chancellor, at the very least.
Many of the supposed clues to a concealed authorship are
based on ambiguities in the received texts and in the
inscription on the tomb etc. Since ambiguity was the
Elizabethan norm, the possibilities are endless.
We are mercifully short of biographical details about the
man who was Shakespeare. Good! We know very little about
Domenico Scarlatti or Henry Purcell come to that. Whoever
they were, they would probably be happy to know their works
rather than their laundry-lists had survived.
As for the Beatles, their oeuvre has already been reassigned!
