-Lettre du 14 mai 1642 (de ?): ‘De praeclaris numismati{bu}s tuis, & vero antiquitatis thesauro, maxima cum voluptate legi quae scribis. qare memini, quanta cum voluptate olim nummorum Gorlaei nostri indicem confecerim. Cuius inprimis Graecos maxima cum admiratione magnus Scaliger lustraverat’ [Concerning your famous coins and true treasury of antiquity, I read with the greatest pleasure the things which you write. So I remember with what great pleasure I once made an index to the coins of our Gorlaeus. His Greek coins, above all, the great Scaliger had examined with the greatest admiration]. If this ‘index’ could be found, it would be of considerable interest!” (British Library, MS Harley 376, ff.112r-13v, at 113; Burnett 2020b, p. 1408).
