Giovanni Battista Anfossi

Giovanni Battista Anfossi was an eighteenth-century Italian physician who practised in Rome and wrote Dell’uso ed abuso della cioccolata, a defence of chocolate as food and medicine. His birth, death, education, and institutional appointments remain undocumented, but his professional connection with Rome rests on more than the designation romano attached to his name: in the dissertation’s opening pages he states that he had exercised his profession in the city for several years. His medical career therefore preceded the book’s publication in 1775; its later appearance in 1779 documents the continued circulation of his writing, without independently establishing his activity at that date.

His only securely identified work first appeared at Rovigo, printed by Gianjacopo Miazzi in 1775, under the title Dell’uso ed abuso della cioccolata. Dissertazione storico-medica. Its publication involved an intermediary: the dedication explains that the manuscript had been supplied by the dedicator’s uncle, abbot of San Niccolò di Castel Muschio on the island of Veglia. Addressing Pier Vettore Pisani, Procurator of San Marco, the dedicator expressed the hope that the living author would approve his choice of patron. The volume thus preserves evidence of a manuscript transmitted through an ecclesiastical connection, while leaving Anfossi’s participation in the publishing arrangements uncertain.

Anfossi’s argument addressed a controversy already sustained by generations of European physicians. Chocolate’s growing acceptance as a fashionable drink had not resolved disagreements over its effects on digestion, circulation, and bodily strength. His dissertation combined a historical account of cacao and its reception with an examination of manufacture, ingredients, and therapeutic application. Sugar, cinnamon, vanilla, and milk were consequential components of a compound preparation: assessments of chocolate depended on what was added to cacao, how the mixture was prepared, and the circumstances in which it was consumed. The distinction between the American plant and its European preparations was therefore fundamental to evaluating the beverage’s alleged benefits or harms.

His intellectual method was predominantly comparative and argumentative. He assembled earlier medical opinions, giving particular attention to English discussions associated with Henry Stubbe, and challenged explanations that reduced substances to the elementary qualities of heat, coldness, dryness, and humidity. Nevertheless, his criticism extended to opponents working within supposedly more reasonable medical systems. His position cannot be reduced to a straightforward replacement of Galenic doctrine by experimental medicine: inherited dietetics, physiological speculation, practical observations, and the authority of earlier writers continued to coexist within his defence. Modern historical scholarship has particularly emphasised this breadth of reference and his discussion of cacao butter as a topical preparation for inflamed haemorrhoids.

The governing distinction remained use and abuse. Anfossi regarded chocolate as nourishing and restorative, especially for weak or delicate constitutions, while making its suitability dependent on quantity, composition, individual disposition, and manner of consumption. His catalogue of attributed effects included assistance to digestion, relief of weakness, and various strengthening or soothing actions. These claims express the therapeutic expectations of eighteenth-century medicine. The work’s particular interest lies in the practical problem they address: how a pleasurable, commercially available preparation could be incorporated into an individually regulated medical diet.

The dissertation reached readers beyond Italy before its Venetian republication. An anonymous review appeared in the Gothaische gelehrte Zeitungen in 1776, on pages 282–284, providing a firm contemporary witness to its reception in the German learned press. This notice establishes international attention to the Rovigo publication, although it does not warrant assuming a translation or extensive European influence. Anfossi’s surviving reputation rests on this compact contribution to the literature of cacao: a physician’s attempt to reconcile learned controversy, everyday consumption, and therapeutic judgement at a moment when chocolate occupied all three domains.
