For art historians, it is so interesting to try to figure out, with the materials at hand, what Piero wanted his work to finally look like, but it's a challenge, as the artist's initial sketches have been lost.

Giuliano talks about his beginnings as a director. Vera threatened to leave him when he thought he might accept certain jobs.

With techniques available today, it is possible to distinguish the various layers of plaster used on different days of work, to determine in what order the artists and their assistants applied the paint. And during the cleaning, details can come out that were previously not visible, including buildings and even letters of the alphabet.

Fulvio shows tells us the story of a door, a very famous door, called the Alchemist's Door, also called the Magic Door, or the Door to Heaven, a monument built by Massimiliano Savelli Palombara, Marquis of Pietraforte on the grounds of his villa in Rome.

Comedian and actor Caterina Guzzanti is a guest at a middle school in Afragola, in the province of Naples, a school named after Rita Levi Montalcini. Guzzanti meets with the students from the theater class for a lesson on the imagination, which has a lot of importance in her work but was also very important to the great researcher from Turin, Montalcini.

Giuliano and Vera talk about some of the colorful episodes in their time together on set. Vera tells about how Giuliano accepted her daughter, Elisabetta, from a previous relationship.

Retouching the painting is a very delicate job, and is done in such a way as to be reversible, and respectful to the original.

Take your time with this episode about Rome because it is chock full of information. Il Campidoglio, also called Monte Capitolino, is the smallest of the seven hills of Rome, but it's the most important because that's where the mayor's office is, as well. Where did the word "capitol" come from? Fulvio has the answer. He also talks about where the word "money" comes from. And you will recognize the name of the architect who designed the piazza and its surrounding buildings.

Rita Levi Montalcini talks about when she won the Nobel Prize in 1986. Her niece, Piera, tells the story from her point of view, and Paola Tarassi, a research student of hers, tells about studying with her after she had already won the Nobel.

Giuliano and Vera were of one mind regarding respect for workers and fighting against intolerance. One episode that particularly struck Giuliano was the news from the United States involving Nicola Sacco and Bartolomeo Vanzetti, two Italian immigrants, and anarchists, who were unjustly arrested and condemned to the electric chair in 1927. Montaldo would go on to make a film about that story.

We take a look at the details of Piero's Resurrezione, details we might not notice by looking at the painting as a whole. Why is Christ not dressed in white? Is there something special about the countryside in the background? The answers are fascinating.

Rita Levi Montalcini felt that imagination was the "secret sauce" of her research. And this encouraged her to turn to young people, who have plenty of imagination. She didn't hesitate to teach kids of junior high school age, which came as a surprise to some people, since she was a winner of the Nobel prize.

Giuliano and Vera talk a little bit about the music for the Sacco and Vanzetti film, as well as a serendipitous moment in NY connected with that. When the film came out it had success, especially with young people. Their outrage about the unfair trial led to the governor of Massachusetts recognizing the unfairness of their trial.

Had the Resurrection always been in the same spot or had it been moved? We are taken through the questions journalists and historians have to ask: where, when, and why. A researcher, after much research, finally found the answer.

Rita Levi Montalcini dedicated a great part of her life to young people, especially young researchers, and though she had no children of her own, she felt that all kinds of young people were like sons and daughters to her.
