The text refers to Bembo. I hadn't come across it before so thought I'd post it for those who haven't seen it either - very revealing. It seems to lend weight to the idea that the family (or at least Galeazzo Sforza) would have no scruples about showing a relative or ancestor in a less than flattering light.For Esther Johnston with many grateful memories Gertrude Moakley.
The following year Galeazzo Sforza (Francesco Sforza's son) commissioned him to return to Pavia for more work in the halls of his Castello. The walls were to be decorated with scenes showing friends of the Count and their dogs in varous hunting episodes. In the written instructions of Count Sforza we read such directives as:
Item, that Alexio is to be shown being thrown from his horse by a stag, with his legs in the air.
In another scene the same Alexio was to be shown attacking the offending stag with his sword. In addition to the hunting scenes, instructions were given to paint Duke Giangaleazzo with all his servants "da naturale", and likewise the Duchess Catalina. Other ancestral Dukes and Duchesses were also to be shown: Fillippo Maria, Francesco, and Bianca with their councellors. The directions go into great details as to costume and the colours to be used. It is evident that the family (or at least Galeazzo Sforza) was not dependent on its artists for decorative ideas.
