Biography
Giovanni Battista Audiffredi was born on 2 February 1714 in Saorge, a town in the County of Nice, part of the Duchy of Savoy, and he passed away on 4 July 1794 in Rome. Although he was born in an area influenced by French culture, he is considered an Italian scholar due to his life's work and connections, spending most of his years in Rome with the Dominican order. He became a priest in the Order of Preachers, dedicating himself both to religious life and scientific study, a common mix among well-educated clergy of the eighteenth century.
Audiffredi worked as the librarian of the Biblioteca Casanatense in Rome for many years, where he excelled in cataloguing and expanding the library's collection. The Casanatense, created by Cardinal Girolamo Casanate and managed by the Dominicans, was one of Rome's major public libraries. Audiffredi's scholarly approach greatly improved its standing. He went beyond administration by compiling detailed catalogs of incunabula and early printed books, which served as important references for later bibliographers.
Alongside his librarian duties, Audiffredi was dedicated to astronomy. He made observations from Rome and contributed to the study of celestial events like the transit of Venus across the sun. His work was published and shared with European learned societies, earning him a reputation as an accurate observer. His focus on precise instruments and methods made his astronomical work highly valued by his peers.
Audiffredi also explored numismatics and natural history, interests common among Enlightenment scholars. His study of coins and medals led him to research collections in Roman institutions and write studies on ancient coinage. As a naturalist, he interacted with the classification systems emerging in Europe due to Linnaeus, although these contributions were less significant compared to his work in astronomy and bibliography. Overall, his work shows the wide-ranging curiosity typical of eighteenth-century Italian scholarship within religious settings.
Before Fame
Audiffredi grew up in Saorge when the region was caught between French and Italian cultural influences. The town, located in the Maritime Alps, was under Savoyard rule, which exposed its people to both cultures. As a young man, he joined the Dominican order and received a typical education in theology and philosophy, as well as training in natural philosophy and mathematics. This education set the stage for his later work in science.
Moving to Rome, the intellectual heart of Catholic Europe, opened up opportunities that a small town couldn't offer. His role at the Biblioteca Casanatense gave him access to one of Italy's top collections of scientific and humanities literature. Being close to other scholars, academies, and observatories in Rome helped him systematically develop his interest in astronomy. By the middle of his career, he was recognized for both his bibliographic skills and his work in observational science.
