22Ah, now I see. If I scroll down far enough, the final word on the left side is "References," which brings up the explanation of 1996a and 1996b. I hadn't noticed that.

23Thank you, Ross, I did forget about this detail. It's from 16 years ago, my memory becomes weak.
Re: Trotti 1456 ????
24Just for the record, here is the page in Ortalli. Pratesi 1987a is "Il gioco dei tarocchi e la sua storia," in G.Berti, A.Vitali, I tarocchi (1987) 111-129, https://naibi.net/A/05-TARSTO-Z.pdf. I wonder if he discovered it. Dummett 1993 is Il Mondo e l'Angelo.
