(Sorry to interrupt the conversation and my poor English) I think you should create it.
We never know what the community can do with that information or if you will end up helping an Italian boy with his History class. But inspired by your question I started looking for information alone, and I have to say, that after the 8th and 7th centuries, which is when most of the famous bronze figures are made, it is as if the Nuragic culture had mysteriously disappeared. Right now I am reviewing the classical authors in the search of more information.
