Johann Elert Bode
In 1812 Zuccari established also an astronomical library in the san Gaudioso observatory. In four years the collection grew from 195 to 620 books. Zuccari acquired some of these books from the Berlin astronomer Johann Elert Bode, the secretary of Neapolitan embassy in Vienna Severo Gargani, and the Paris booksellers of the King of the Two Sicilies, Borel and Pichard.
