Collection of 200 letters, in Italian and Latin, the largest number addressed to Luigi (also called Aloysius) Lollino, Venetian patrician and bishop of Belluno from 1596 until his death in 1625; all letters in clear eighteenth-century copies, with careful annotations about the writers of the letters, location of the originals, persons and books mentioned, etc. Another group of letters is addressed to the Venetian senator Domenico Molino, and a smaller group to Wilhelm Schickard, professor of oriental languages in Tubingen. Other recipients are Lodovico Celio Ricchieri, ecclesiastic authorities in Belluno, etc. Among the writers (listed, with biographical notes in a separate index), those with the largest numbers of letters in the collection are Lorenzo Pignoria, Arrigo Caterino Davila (referred to as Enrico in the manuscript), and Panfilo Persico. Others present in the collection include Gaspare Barleo, Pietro Bembo, Scipione Chiaramonte (mathematician), Daniel Einsius (of the Univ. Leiden), Jacopo Golio (mathematician and orientalist), Angelo Grillo, Domenico Lampsonio (poet and painter), Wilhelm Meursius, Andrea and Donato Morosini, Fulvio Orsino, Antonio Possevino, Cardinal Richelieu, Martino Sandelli, Paolo Sarpi, and Pierio Valeriano [=Giampietro Bolzanio, secretary of Pope Clement VII]. The compiler is unknown; most letters concern in some way the town and district of Belluno.
