Reticolarità cardinalizie. Spunti di riflessione per l’analisi di un ceto curiale (secolo XIII)

The essay delves into the cardinalate's social network within the Roman Church during the 13th century. The study explores how the College of Cardinals gradually evolved, particularly since the 11th-century reforms, reaching significant institutional development during Pope Innocent III's pontificate. This text serves as a reflection on the systemic observations derived from prosopographic research detailing the biographical data of individual cardinals. Significant attention is given to the cardinalate's reticular nature, where the individual cardinal acts as the nexus of a complex social network. Such networks were molded by factors like geographic origin, ecclesiastical affiliation, and familial and social background, all of which influenced papal decisions and the broader church hierarchy. The research also emphasizes the potential of digital prosopography and Social Network Analysis in drawing systemic insights into ecclesiastical networks. One case study explored is the familia of Cardinal Gerardo Bianchi, which illustrates the intricate social webs formed around cardinals. The familial network, including clerical and lay members, offers insights into recruitment within the curia, illustrating the importance of both personal connections and institutional affiliations. The analysis underscores how these networks extended beyond ecclesiastical bounds, influencing broader political and social structures. Overall, the essay highlights the crucial role of individual cardinals in shaping and being shaped by their networks. It suggests that further exploration using advanced analytical methods could yield deeper understanding of the ecclesiastical and social transformations within the medieval Church.
