With this second volume the authors present another important part of the corpus on the architecture of the Society of Jesus in Italy. The first volume — by Richard Bosel, dealing with the Roman and Neapolitan Provinces — appeared in 1985 also in the Verlag der Osterreichischen Akademie der Wissenschaften (Austrian Academy of Sciences Press) and had a second edition already in 1986. Iti is the aim of the research project to deal monographically with the architectural heritage of a whole province of the order during two centuries and to research into its manifold historical connections. Altogether forty establishments of the order are presented — colleges, profess houses, residences, novitiates, academies and especially the churches annexed to all them. As regard the areas, the volume deals with Lombardy, Piedmont, Liguria and the isle of Corsica, at the time belonging to Genoa. Analyzing the buildings of the one religious order that was, maybe, the most important one for the counter—reformation, will enlarge the general picture of Italian architectural history by important aspects.
