This is an incredibly minor flaw in the typesetting, one that I thought I had dealt with, but that didn’t make the transfer from my notes to the actual physical book.
In the Dramatis Personae, on the page listing the Capulletti family, there is a diamond beside Luigi’s name, denoting a character from Shakespeare. That diamond should be next to Antony’s name – Antony Capulletto is a Shakespearean character.
(Oh, and on the same page, the typesetter misspelled it as "Anthony". It happens)
This is an important point, and one that I want my readers to be aware of. There’s surely more than enough to confuse readers already.
Cheers,
