Annibale degli Abati Olivieri (17 June 1708 – 29 September 1789) was an Italian archaeologist, numismatist and librarian, considered the founder of the Biblioteca Oliveriana, Pesaro. An aristocrat without heirs, he was the author of works of archeology and numismatics. He also discovered the site of a Roman sacred grove, the Lucus Pisaurensis at his property on Collina di Calibano (Hill of Caliban) in the countryside of Pesaro, at which he unearthed the 13 Votive Stones of Pesaro.[1]
