I haven't heard that one. As far as I can see, the only 17th century Shakespearean operas were British: The Tempest (1674) by various composers, and Purcell's The Fairy-Queen (1692). There were several more in the early 18th century, but the first Italian one seems to have been Ambleto (1706) by Francesco Gasparini.
