Abstract
The dataset contains metadata describing the Princes of Biscari (Paternò Castello) correspondence, one of the most important noble families in Sicily during the modern era. The dataset was created with the digitization of letters preserved in the Biscari Archive, held at the State Archive of Catania, and this digitization initiateed a Historical Network Analysis research project aimed at reconstructing the family’s relationships and how its members interacted with the political class, the religious class, and the monarchy. After digitization, the letters were curated in a database and analyzed.
