Francis de Callatay, to whom this volume is dedicated, rightfully deserves an homage. His passion for numismatics is wide-ranging, but of special interest to us are his many and ground-breaking articles devoted to antiquarianism and the reception of antiquity. Some of them are devoted to specific themes, such as the interest for Seleucid coinage or royal Bosporan coins in pre-Revolutionary Europe, some are more anthropological (such as his observations on the high proportions of Jesuits and medical doctors amongst numismatists of the past), and finally several are dedicated to individual figures such as Charles Patin, the count of Caylus, Jean-Jacques Barthélemy or the abbot Leblond. In the latter spirit, this notice hopes to serve as a brief introduction to the work of Louis Jobert, S.J. entitled La Science des Médailles, pour l’instruction de ceux qui commencent à s’appliquer à la connoissance des médailles antiques & modernes, that is ‘The knowledge of medals, or, Instructions for those who apply themselves to the study of medals both ancient and modern,’ which “served for nearly two centuries as a first rate reference work.”
