1.) It happened pureley accidental,- 2 authors invented these ideas independently !
2.) B.Griffin 14 years later plagiarized from T.Watson
3.) Both authors were identical, the author using different pennames or pseudonyms at different times
There would be very very many powerful arguments to accept thesis nr.3 that "Ekatompathia" and "Fidessa" must have been poetical works written under pennames by the same poet genius at the age of 18 and 32 years (Marlowe alias Shakespeare) but even the strongest arguments would shatter at the cliffs of the fatal orthodox Stratfordian narrow-mindedness. Its at present not worth the effort! One inevitably would be disposed at the landfill of conspiracy theorists.
