And for anyone needing a further fix, Netflix has just released
Medici: Master of Florence, a dramatization of Cosimo's early career as head of the Medici bank. It suffers from a variety of niggling issues (the architectural history is off, the women are criminally if predictably underused, and you're telling me a city of tens of thousands only has one apothecary?), but the pictures are pretty and Dustin Hoffman is interesting as Giovanni. It may be more accessible for players trying to get into the look and feel of the place than a documentary.
