De viribus quantitatis (Ms. Università degli Studi di Bologna, 1496–1508), a treatise on mathematics and magic. Written between 1496 and 1508 it contains the first reference to card tricks as well as guidance on how to juggle, eat fire and make coins dance. It is the first work to note that Leonardo was left-handed. De viribus quantitatis is divided into three sections: mathematical problems, puzzles and tricks, and a collection of proverbs and verses. The book has been described as the "foundation of modern magic and numerical puzzles", but it was never published and sat in the archives of the University of Bologna, seen only by a small number of scholars since the Middle Ages. The book was rediscovered after David Singmaster, a mathematician, came across a reference to it in a 19th-century manuscript. An English translation was published for the first time in 2007.[
I found this snippet:

I found the text (handwritten, but good readable)

in three partitions with content

... but I don't know, if this will be of big help.

One article in full (which briefly mentions "trionphi") and part of another (preceding it), the one in full on the magic tricks, especially card tricks in De Viribus and the other on it and other works and his life, are reproduced in Google Books at

The full article starts on p. 123. I have made some comments on the card tricks there, in relation to the Magician card, at viewtopic.php?f=23&t=384&start=100#p19547.

The part about his being with (aupres de, French Wikipedia says) Leon Alberti was new to me; English Wikipedia doesn't mention it. Looking at the French Wikipedia article at that point, I see no reference. Perhaps it is just speculation. They were both in the same city at the same time and both interested in problems of perspective and geometry. So it makes sense that they would have known each other. I just wonder if there is some record of it.

3 references.
There should be a lot more.
The last one is the most interesting and the better documentad I believe...

1.
Sciences de la Renaissance Page 93

Rome 1470 : he is living in Alberti's home

2.
The Mathematics of Harmony Chapter & Page 47

Piero della Francessa introduces Paccioli to his new mentor : Alberti

3.
Les grands auteurs en comptabiité page 15

1464 : Court of Federigo de Montefeltro (Urbino) : Alberti makes him the teacher of Antoni Rompasi

NB
In all the data offered by the 3 references , also of interest to me is that he is presentad to Francisco de la Rovere Pope in 1471 (RIP Aberti 1472) and becomes friend of Juliano de la Rovere : Cardinalat Avignon 1476-1503, Pope 1503 - 1513 (if my memory is good).
We have studied attentively de la Rovere connections in Avignon in another thread...
