The publication of the Saggio orittografico in 1780 established a new methodology for examining fossilized remains within Tuscan chalk deposits. By utilizing microscopy to analyze minute structures, the Camaldolese monk identified patterns that bridged the fields of geology, zoology, and paleontology, ultimately laying the early foundations for what is now recognized as the discipline of micropaleontology.
Religious Life and Academic Formation
Born in Pratovecchio in 1736, he entered the Camaldolese order as a young man. His early religious life centered at the Monastery of Santa Maria degli Angeli in Florence, followed by a transfer to the Monastery of San Michele di Pisa. Despite his primary commitments as a regular priest, he maintained an intense focus on mathematical studies. He ascended to the position of abbot in 1776 and later served as the superintendent of the abbey of Santa Mustiola in Siena starting in 1780.

Upon his appointment in Siena, he directed his research toward the microscopic inspection of fossil samples sourced from localities near Siena and Volterra. His 1780 work, Saggio orittografico ovvero osservazioni sopra le terre nautilitiche ed ammonitiche della Toscana, provided a detailed account of regional geology and fossil distributions. This contribution secured him a professorship in Mathematics at the University of Siena under the patronage of Grand Duke Pietro Leopoldo. He also served as secretary of the Accademia dei Fisiocritici, a group dedicated to the natural sciences.
Expeditions and Meteorological Observations
His inquiries extended beyond stationary fossil collections. In 1783, he conducted field research throughout the Romagna region to collect samples and investigate thermal springs. His scope of interest also encompassed astronomy and atmospheric events. Following an aerolite shower in Lucignan d'Asso on 16 June 1794, he authored Sopra una pioggetta di sassi accaduta nella sera de' 16 giugno del MDCCXCIV in Lucignan d'Asso nel Sanese, documenting the physical characteristics of the meteor samples recovered.
Scholarly Legacy
Over the span of nearly a decade, between 1789 and 1798, he produced the multi-volume Testaceographia ac Zoophytographia parva et microscopica. His efforts earned the respect of contemporaries, including Charles Lyell, who ranked him among the most significant naturalists of the eighteenth century. He was a member of the Academy of Sciences of Turin. Upon his death in Florence in 1808, he bequeathed his extensive collection of fossils to the state.
