In the Brembana Valley, the river reigns supreme. In fact, there is still a functioning water mill for grinding corn, as well as people passionate about maintaining centuries-old traditions.

Here and there in the small villages of the valley, there are interesting frescos hearalding back to earlier times. Two local recipes are offered: stuffed curly cabbage leaves and Taragna polenta, a kind of cornmeal with the addition of buckwheat.

The fine white mold that forms on the cheese helps give it its characteristic flavor, but it is also painstakingly scraped off each round. Before the high-altitude pastures are ready for grazing, humans take advantage of the snow and the trails.

Lo stracchino is a soft, mild but flavorful cheese that's spreadable, and we find it in supermarkets all over Italy. But the kind Francesca's family produces in the mountains, with traditional tools, is on a whole other level. Why is this cheese called stracchino? There is a fascinating reason. Watch the video.

Il formaggio (cheese) is rarely missing from an Italian kitchen. This video takes us to the mountains north of Bergamo where the Monaci family has kept the family cheese-making tradition going, beginning in the stable where the cows are taken care of during the colder months.

We've come to the end of this journey to find Valentina. Philip Rembrandt continues to wait, and Valentina never forgets him.

Michele is distraught about Beatrice Cenci but at this point, there is nothing he can do. He confides in Costanza Colonna, who warns him to keep his ideas to himself.

Which came first? Blow-Up or Ciao Valentina? Which work stole from the other? In any case, there are some striking similarities.

Michele returns to the palace but the Cardinal is not happy. Beatrice is on trial at the papal court and is trying to defend herself.

Crepax's stories were based on imagination and vision. In those years, artists contaminated one another's works, and there was even a curious connection between Crepax's Ciao Valentina and Antonioni's Blow-Up.

Michele is at dinner at Fillide's home. The conversation turns to a grim story of patricide involving someone he knows and he can't let it go. Things get out of hand.

Who was the model for Valentina? Certainly, the actress Louise Brooks who portrayed Lulu in the movie Pandora's Box directed by G.W Pabst (based on two plays by Frank Wedekind), but also Crepax's wife, Luisa Mandelli.

Michele finishes his painting of Fillide and they have a moment to get to know each other better.

Just as in Cubist art, Crepax would design his figures to be seen from various points of view simultaneously. Sometimes he would use small windows to attract attention rather than making them larger.

Caravaggio (as he begins calling himself) and Ranuccio play real tennis. Who's going to win?
