The essay reconstructs the relationships – for about a decade – between the Abbot Angelo Bottari from Chioggia and the Count Giuseppe Beltramelli from Bergamo, in the light of an unpublished epistolary (entirely transcribed in the appendix) that sheds light on the common interests linked to the collection of antique coins and modern medals of Illustrious Men. The letters in question provide a wealth of information, especially on the formation of the abbot’s numismatic collection, as well as on his role as a buyer and scholar, which saw him as one of the most active protagonists in Italy in the late 18th and early 19th centuries.
