ANN: Prince Stanisław Poniatowski (1754-1833) and his engraved gems: a Polish Roman collector of neoclassical intaglios (28 Oct, 2025, 7 pm Berlin time, Online)

The so-called ‘Poniatowski gems’ are supposedly well-known, with books and articles published about them for the past two hundred years. Nevertheless, many of them are handled (at auctions notably) without being identified as such. And there had not been a clear presentation of their stories and specificities. I have attempted to fill this lack when I studied two of them that are kept at the American Numismatic Society in New York.

Hadrien J. Rambach is a French citizen who has long resided in London before moving to Brussels. Formerly in charge of Roman coins for the company Spink & Son, he has since established his own company, advising high-level collectors on their purchases, and trading in cameos and intaglios. Using his extensive library, he regularly publishes scholarly articles on Ancient coins, on engraved gems, and on the history of collection, and is currently registered as a PhD-student with the universities of Lille (FR) and Tübingen (DE).
