Well - I hope that when you write your letter you make it clear that Carre
has included a piece by Corbetta in his first book which includes his
observations on stringing. This is from Corbetta's 1648 book and Carre
evidently thought it OK to play it with a fully re-entrant tuning.
You have
1.The reference to the law suit between Carre and Corbetta and the
printer Bonneuil which isn't widely known and does indicate that Corbetta
and Carre were aware of one another's work and probably knew one another.
2.Details of sources from which Castillion has copied information.
