Did Thomas Nashe insert a subtle clue that Marlowe wrote Shakespeare in his Have With You to Saffron-Walden? In this pamphlet, Nashe mentioned Richard Harvey, a minister who was the brother of Nashe's nemesis, Gabriel Harvey.
Nashe wrote that Richard, who supported the philosopher Ramus, placed the ears of an ass on the head of Aristotle:
This is that Dick that set Aristotle, with his heels upward, on the school gates at Cambridge, and asses’ ears on his head; a thing that, in perpetuam rei memoriam, I will record and never have done with…This is that Dick of whom Kit Marloe was wont to say that he was an ass, good for nothing but to preach of the Iron Age. 
Can you think of a Shakespeare play in which a character sports asses’ ears on his head? Bottom in A Midsummer Night’s Dream, of course. What’s more, Bottom is associated with religion, as was Richard Harvey, misquoting the Bible: “The eye of man hath not heard, the ear of man hath not seen, man's hand is not able to taste, his tongue to conceive, nor his heart to report what my dream was" (IV.1.218-21). 
Nashe published Have With You to Saffron-Walden in 1596, while A Midsummer Night’s Dream dates from 1595-96. Nashe’s report, “This is that Dick of whom Kit Marlowe was wont to say that he was an ass” may be a subtle clue that Marlowe had recently turned Richard into an ass onstage via proxy, by turning Bottom into one in A Midsummer Night's Dream.
