However, no cards from this region before the 18th century are known to have survived to prove or disprove this theory.[
Dummett conjectures that this family of decks, especially those of Viéville's design, originate from the Savoy- Piedmont- Lombardy region and were used until the collapse of the local card manufacturing industry at the end of the 17th century (as described above). Viéville's ordering of the trumps is almost identical to 16th century orders in Pavia and Mondovì. However, no cards from this region before the 18th century are known to have survived to prove or disprove this theory.[23][24]
