**************************************
Sabbioneta
ca. 30 km north of Parma, in that time at Mantovan territory. In 1484 it was reigned by the second son of Ludovico Gonzaga and Barbara of Brandenburg.

Gianfrancesco, 1st Conte di Sabbioneta e Signore di Bozzolo (1479-96), *1443, +Bozzolo 28.8.1496; 1m: 1479 Antonia del Balzo; 2m: ?;
In 1484 Francesco Gonzaga I, ruler of Ferrara 1478-84 and elder brother of above mentioned Gianfrancesco, died at 1484-07-14. The heir, Francesco Gonzaga II was 18 years old, likely his elder uncle Gianfrancesco (who owned Sabbioneta) played likely a stronger role - then.

One might bet on it ... the Statutes should have been written after 1484-07-14.
Sabbioneta is 1484 more the name of a region than a city. In 1484 there seems to be a village and a castle. Sabbioneta takes stronger development in second half of 16th century. It becomes an ideal city, something like Sforza's Sforzinda.
This is the modern Sabbioneta. One still recognizes the plan of an "ideal city".

It was build up c. 1560, but this isn't interesting for my purpose. The riddle is, what had been there before, cause from the year 1484 there is a Trionfi card note referring to Sabbioneta.
This is the Theatro Olympico ... maybe similar to that, what is described Alberti's "Momus".
