gems, early lapidaries, early gemology, early mineralogy

Tomasoni presents a critical edition and glossary of the Lapidario Estense, a medieval Italian vernacular lapidary whose principal sources include Marbode of Rennes’s De lapidibus and Bartholomaeus Anglicus’s De proprietatibus rerum. The study makes the lapidary text available in an edited form and provides a glossary for its medieval vocabulary, making it particularly valuable for the history of Italian gemstone and mineral terminology and for tracing the transmission of classical and medieval traditions concerning stones and their properties.
