I agree generally there should be consensus among high quality sources that X is an Italian invention and the source should actually say words to that effect I don t oppose an article that takes a broad view and includes all sorts of technology developments related to Italy but the article should be moved to Timeline of Italian invention and redefined appropriately Many editors treat these List of inventions articles like that anyway including all sorts of things that aren t strictly inventions or strictly Italian The solution there is to make sure the reader understands that s what the list is not purport to be something else
