Well, the numbers at the d'Este cards ...Ross G. R. Caldwell wrote: There are also numbers on the Catania and Este cards. The Catania numbers are consistent with the Charles VI, which is not surprising since it looks like the same workshop made them. The Este cards are consistent with both the B and A orders, since the Sun is numbered "18".

This is 0 the Fool

This is 1 the Magician

This is 5 the Pope

This is Temperance

This is 16 the Star

This is 17 the Moon

This is 18 the Sun

This is 21 the World
*******************************
The Ursino cards

21 World ... nothing, understandable, if we assume an "unnumbered trump"

Temperance ... nothing, although it should have a number

11 Hermit ... the 11 seems very clear

10 Chariot ... the 10, not as good recognizable in the same way, is marked at the same place
