His research stems from excursions on Mount Baldo during which he collected and catalogued many samples of plants, animals and fossils.
This collection is described in the work "Viaggio di Monte Baldo dalla magnifica città di Verona", published in Venice in 1566. Even today you can admire part of the collection of Calzolari at the Museum of Natural History in Verona, among the most interesting objects are the fossils of Bolca.
It is no coincidence that the residence of Calzolari is on the slopes of Monte Baldo near Rivoli Veronese. Mount Baldo due to its geographical location near the Po Valley, Lake Garda, Val'Adige and the Alpina chain has been for centuries a place of tree species becoming in effect an open-air botanical garden with 350 different plants cataloged by the same Calzolari.
The house of Calzolari is still located in Rivoli Veronese near Corte Campana, the property has belonged in the past to the descendants of the naturalist related over the centuries with the families Badile, Gaioni and Nichesola.
