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.

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.

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.

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

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.

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

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.

Vera's daughter was a teenager when Giuliano began courting her mother. Giuliano tells some stories about World War II and how crazy things were.

It's rare for a work of art to become the symbol of a city and even be part of its coat of arms, but this did indeed happen in Borgo Sansepolcro. Piero's Resurrection may be thought of as a fresco, but it's much more complicated than that, as we learn in this segment.

Vera talks about her parents and how they met and fell in love. Her mother was a stage actress and her father a military commander.

Piero was not just a painter; he was a member of an important family in Borgo Sansepolcro. There is a fresco painting attributed to him that might have alluded to the family business, which was producing and selling leather goods.

The name of the villa was inspired by the story of Dionysus who watched Ariadne while she slept. It was excavated first by the Bourbons but was buried again. Later in the 50s, digs were resumed and now, it can be visited in all its glory.

The restorers take us through the meticulous cleaning process involving Japanese rice paper, a gel made from marine algae, and a solvent.

Restoring the Resurrection was a lengthy and complex process, consisting of reinforcement, cleaning, and the retouching of the painting itself.

The host describes the fascinating story of a British army captain who, during World War II, happened to have read Aldous Huxley's words (quoted in the previous segment), and remembered them just in time.
