Consider some examples of arguments which would support this assumption:
1.) There is no reasonable cause why the literary work of Drayton [born at the same time than Marlowe(1563?)] begins so strikingly late *1), after Marlowe's death (similar to Chapman, Heywood, Shakespeare....)
2.) The emblem of the "Mercurius Rod" is not only on Draytons "Ideas Mirrour" and "Piers Gaveston" but also on ,Shakespeares "King Lear", and other literay pieces of authors most likely to represent additional code names of our Poet Genius (e.g., Bodenham, Markham, Dekker, Wither a.o..)
3.) One can interpret Draytons Sonetts in "Ideas Mirrour (1594) only as biographic (e.g. Sonett 42) and literary (e.g.Sonett 62) equivalents of Marlowe's fate and style :
Amour 42 ( Excerpt M.Drayton, Ideas Mirrour 1594)
Cancell my name, and blot it with dispayre;
So shall I bee as I had never beene
Nor My disgraces to the World be seen
Amour 62 (Excerpt M.Drayton, Ideas Mirrour 1594)
[throughout the "complementary dialectics" of Marlowe's life Motto(Quoad alit me destruit)
When first I ended, then I first began,
…Where Most I lost, there Most of all I won
…What Most I seem, that surest am I not
…Burn'd in a sea of ice and drown'd amidst a fire
4.) Draytons »Endemion and Phoebe«(1595!) represents precisely the ancient mythological metaphor or Parabel of Marlowe's life and fate.- The female equivalent to Apollo "Phoebe" (also "Selene", the Moon-Godess) produced a deep eternal sleep in the shepheard »Endymion«[Marlowe] in his 30th year of life
5.) The singular most plausible motif, that a month prior to Shakspere's death 1616, Drayton[alias Marlowe] and Jonson met with Shakspere in the province town of Stratford ["Shakespeare, Drayton and Jonson had a merry meeting, and it seems drank too hard, for Shakespeare died on a fever there contracted ] would be to arrange preparations for a will and for the fake of a future Funeral Monument....
6 ) Drayton on his visit(s?) to Stratford was medically treated by the son in law of Shakspere, the physician John Hall (Halls Entry: »Obser.XXXII-Mr Drayton, an excellent Poet, labouring of a Tertian, was cured by the Following....«) Hall never mentioned his father in law Shakspere as a famous man or Poet ..why Drayton?.
7) How could Francis Meres in 1598 have known of Draytons "Polyolbion" and its detailed contents, (»Geographical and Hydrographicall of all the forests, woods, mountaines, fountaines, rivers, lakes, flouds, bathes and springs that be in England«) "which were published only 14 years later (1612)
(... it requires a deeper understanding of who the highly educated Meres was and how he could have had access virtually to the complete and the most recent "literary scene and events" of the time in England ...
9)Why on Epitaph 120 the anonymous author of "Wits Recreations" (1641), which can be recognized as Marlowe/Shakespeare, clearly identifies himself with Michael Drayton?:
Epitaph 120 (Aus »Wits recreations«)
"On Mr. Mychael Drayton buried in Westminster"
(…)and when thy [Drayton] ruines shall disclaime
to the treasury of his [the poet] name
His [the poet] name which cannot fade, shall be
An everlasting monument to thee [Drayton]
You may notice that the author differentiates between 2 separate personal entities (the true poet versus the poet named Drayton- Why?)
10) Why does Drayton in his poem "Matilda" 1594 identify himself with "Tarquin" (alias Marlowe - lately revived to live another Age) ?
Lucrece of whom proude Rome hath boasted so long.....
[Tarquin]... lately reviv'd to live another age
And here arrived to tell of Tarquins wrong
( …) She [Lucrece] is remembered, all forgetting me,
Yet I as fayre and chast, as ere [ever], was she [I was she !]
11) John Weevers Epigram 23 "Ad Michaelum Drayton" (»Epigrammes in the oldest cut«,1599) tells us that somebody else is hiding behind Drayton ,
( …) to keepe another when they do intend,
twenty to one for Drayton they will send,
yet bade him leave his learning, so it fled,
And vow'd to live with thee [Drayton] since he [Marlowe?] was dead
12) In »Palladis Tamia« (1598) Francis Meres' quantitative and qualitative "amount" of poetic appreciation for Drayton is clearly greater than for Shakespeare. (Moreover, it is hard to understand and requires a more plausible explanation of who was the highly educated Meres and how he could have had access virtually to the complete and most recent literary information and scene of England
13) In »Englands Parnassus« (1600, Edit.Robert Allot) the number of poetic contributions of Drayton(163) compared to Shakespeare (91) are almost twice as large.-
14) Shakespeare expert so far have not explained F.G.Fleay‘s insight (1891), that Drayton's influence on Shakespeare was direct and powerful. Shakespeare was dependent on Draytons words, thoughts, structure and Contents...., L.Whitacker (That Draytons Influence is direct and forceful; that Shakespeare's dependence upon our author[Drayton] ….is one of word, thought, structure and content )
15) The third Edition of the latin handbook on Rhetorics from a highly educated Thomas Vicars (»Χειραγωγία, Manuductio ad Artem Rhetoricam« (1628) deals intensively with highly praised Drayton and only marginally with Shakespeare, giving his name only ambiguously and allegorically, recognizable only for a few.(... celebrem illum poetam qui à quassatione [shake] & hasta [speare] nomen habet,)
16) It is hard to understand why George Wither in »The Great Assises« connects Michael Drayton
and Christopher Marlowe so closely.
[Drayton] To amorous Leanders, and them move
Through seas of teares, to swim to her they love [Marlowe's Hero &Leander]
His [Draytons] Tragique Legends are with force endu’d
To soften Scythans, and Tartars rude, [Marlowe's Tamburlaine]
17) Peter Heylyn in his »Cosmographie in four Bookes« (1652) in the section of Englands 10 most important contemporary poets identifies Michael Drayton as »The Ovid of the English Nation«, and does not mention Shakespeare with a single word? Reverend John Ward from Stratford noticed this conspicuous feature in his diary (1663): »Wether Dr.Heylin does well, in reckoning up the dramatick poets which have been famous in England, to omit Shakespeare«
18) Aston Cokain (whoever he was) in a Poem (page 110) "To my worthy, and learned Friend Mr. William Dugdale, upon his Warwickshire Illustrated" created a strange link between Shakespeare's Muse in Stratford and Drayton (»sweet tongu'd Drayton that has given renown unto a poor (before) and obscure town« [Stratford upon Avon] . Why Drayton made Stratford a famous town, ?
19) Cokain also wrote a poem "On the death of my very good friend Mr.Michel Drayton", in which you notice not only the First Folio "praise" on Shakespeare:,
"It is in vain to say thy lines are such
as neither time nor envies rage to touch"
but also the ambiguous plurality of the Poet (contination of the Poem)
for they must live and will whiles there's an eye
to reade, or wit to judge of Poetrie
you Swans of Avon , change your fates, and all
sing, and then die at Draytons Funeral:
Sure shortly there will not a drop bee seen
and the smooth-pebbled Bottom be turn'd green
when the Nympes (that inhabit in it) have
(as they did Shakespeere) wept thee to thy grave
20) There do not exist any entries on Draytons burial wheresoever in Westminter Abbey! there is consense among experts that Drayton is not buried in the Poets Corner. Why Drayton did not leave a will ? Why there does not exist an exact date of Draytons death ?
Conclusion: These little but significant facts and questions (among many more) can reasonably only be answered or resolved if we assume, that Marlowe used the name Michael Drayton as one one his various code- or pen-names..-
