La Sardegna bizantina e alto-giudicale
Boscolo was professor of Medieval History at the University of Cagliari. This book is part of the series Storia della Sardegna Antica e Moderna and treats the Vandal rule in Sardinia up to the first Giudici (judges) of Sardinia, with much attention for the development of political offices under the Byzantine period that led to the formation of the figure of the Giudice.
