In this case, my first turn would be to Jens Hoyrup akira.ruc.dk/~jensh/
i) a specific answer (unlikely);
ii) an idea of where a specific answer might be found (more likely); or
iii) a good explanation of why it's a malformed question (most likely)
In this respect, history and math are similar.
Corollary: questions with yes/no or number answers are often not well posed, in both math and history
And that's where I'll have to leave it for today.
