John Warren's dedicatory poem devoted to William Shakespearean can fully only be understood in the context of the Marlowe / Shakespeare authorship problem. The fatally threatened poet-genius Marlowe had to fake his death (1593) und live a second life writing under many pseudonyms such as Shake-speare he borrowed (for safety reasons) from a living man in London named Shakspere.
Most likely he wrote (as "John Warren") the dedicatory poem devoted to himself as William Shakespeare: Note some remarkable conspicious points of the farce: Warren differentiates between 2 personal entities and lifes (L=Line)
L2: Marlowe alias Shakespeare corresponds to "Virbius ": Virbius as the italian counterpart of greek Hippolytus,who had been trampled to death by the horses of Poseidon, and who was restored to life by Asclepius (Virbius' ressurection)
L2: He showes himself "twise lived", in his second concealed life as revived art of Shakespeare...
L3: it is (it was) love (admiration) shown to him (the poet Shakespeare)
L4: the labor was his (the "incognito poet" genius alias NN) , the glory belonged to the other (Shakepeare)
L5: these dedicatory learned poems belong to the poets second life (his after-birth)
L6: Shakespeare's name (not the person) remains immortal on earth
L7: Will (Shakspere Stratford?) should enable the learned to understand (to see,)
L8 that the Muses gift (of Shakespeare) were infused to another (on thee)
L9 the mythological god of poets, Momus, personifiction of satire and mockery , may barke Carpine????
L10 the ignorant slave Davus of Pamphilus ("Andria", comedy of Terentius, adapted by Macchiavel!)
L11 Some know of the worth of the poets desert (!)
L12 and are capable of judgment to discerne the true poets Art
