Question: Simone da Orsenigo was an Italian architect and builder of the 14th century, his name is on the list of masters working on which term, for an Italian cathedral church?  
Sentence (from "Duomo"): The formal Italian word for a church that is now a cathedral is "cattedrale"; a "duomo" may be either a present or a former cathedral (the latter always in a town that no longer has a bishop and therefore no longer has a cathedral, as for example Trevi).
Relevant evidence: No
