Ercole Graziadei's Herbarium (FER-GRA)

The herbarium of Ercole Graziadei, Count of Massenzatica, is an early 19th century collection purchased in 2024 by private individuals in Codigoro for its great historical value, excellent state of preservation, and, not least, the frequent occurrence of collection notes of scientific value for the Ferrara area (specimens also from the Ferrara Botanical Garden). The collection consists of four small bound volumes, in which the pages containing small, numbered plant specimens, protected by paper folds, alternate with a rich textual treatment, where each number leads to a detailed description with ecological notes, commentaries, references to published texts or plates, and, indeed, often precise collection localities.

It includes specimens collected by other authors, including Antonio Francesco Campana, and overall, various handwriting styles are recognizable, along with evidence of a "stratified" constitution, likely spanning at least a decade (specimens dated 1827 and 1834 have been glimpsed).
