There is a Dutch family "van Waesberghe" with a long ancestor research and activities in the printing business in the Netherlands with a "JAN VAN WAESBERGHE (DE OUDE), geb. Antwerpen 1556, ovl./beg. Rotterdam Grote Kerk 25-5-1626" and following strange names in the family with "Jansonius". Johann Anton Janson von Waasberghe, Ratsherr in Danzig" might be well a descendent from this family. Janson isn't a common German name. And the region of Danzig was known for inhabitants which came from Holland and the Netherlands.

The text "Das Carneval gelehrter Phantasien" (1763) was to our knowledge the first, which noted Cartomancy methodes used by Dutch and German ladies.

The text was written by an anonymous, published in Leipzig and Frankfurt, both the most prominent bookprinting locations in Germany (one might suspect, that there is a professionell printer behind it).
It's a strange accident, that we have in the German language region as first early text about cartomancy somebody who knows the oracle habits of German and Dutch ladies and then as a second very early text an author, who lives in Germany, but seems to have come from the Netherlands. Is it possible, that the author of the Carneval text is identical to the unknown texts of 1747 or the known texts of 1769?
The version of 1769 is not totally identical to the version of 1769. The author Waesberghe tells us in the foreword, that he had arranged minor improvements against the work of 1747, so there is not a 100%-security about the cartomancy date of 1747. If Waesberghe had been the author of the carneval text, then he might have had a reason to embed some notes about divination texts in the new editions of his earlier work.

This statement says, that there was a not changed edition of the work of 1747 in the year 1756 and a slightly variated version in the year 1769.
