YAWN Who says it is just an opinion You Have you done a personal research in about  books or more Sadly it would be not valid wikiNo original research Anybody did the research instead of you that would be a great source Why do not you present it I inform you that about  books or more vs  makes the claim verifiable read here   BTW are you so sure to be born in SPLIT Your mum says so but it just her opinion I would write in your page according to Direktors mum he was born in Split But the opinion that D  was born in Messina shall be inserted as well   PS Anyway I would write according to historians Venice is the birthplace  and I would delete the word opinion until D does not present evidences that historians have no primary sources
