Le Cinque Terre — a place so many visitors from other countries put on their must-see lists — is the topic of this segment. It's a marvelous example of the relationship between humankind and nature.

A quarryman has to have a passion for his work. Every block of marble is a challenge and has to be observed on all sides and many times to make sure it is good. But succeeding in cutting it and taking it out is an enormous satisfaction.

Vennai is the most important marble quarry in Carrara. Luigi Pasquale talks about when he started working there at about 14 years of age.

We visit the 28th chapel where the scene of Jesus before Pontius Pilate is depicted. We also learn a little secret about how these statues were created.

The first place we visit is practically a theater on a mountain, designed and built to replicate places with religious significance in the Holy Land. The mountain, aptly named, is Sacro Monte (sacred or holy mountain) and is located in Piemonte, to the northwest of Milan.

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

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

The Romans were the ones to introduce the culture of wine to the area around Mount Vesuvius as can be seen by what was left behind in places like Ercolano. And it is in Ercolano where a unique cooperative has been set up to cultivate a very special variety of tomatoes.

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.

Coral has been made into jewelry in Torre del Greco since the fifteenth century. In that same century, a variety of grapes arrived from Catalunya, which over time has produced a wine with a unique personality.

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.

Gragnano is a town near Naples known for its pasta production. There are many different shapes and types, but they all are a bit rough to the touch, because they go through a bronze cutter, rather than a Teflon one. That's why the pasta holds the sauce better. Of course, everyone living in Gragnano is an expert about pasta.

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.

This land is not only good for cultivating grapes for wine, but also the special piennolo tomatoes, that keep for several months.

Guido Crepax's son Antonio talks about the day Antonio Custra was killed in May of 1977, during an armed demonstration in Milan. This was during the so-called anni di piombo (years of lead), a period of social turmoil, political violence and upheaval that lasted from the late 1960s until the late 1980s, marked by a wave of both far-left and far-right incidents of political terrorism and violent clashes. Many demonstrators were arrested, but Antonio Crepax managed not to get loaded onto a paddy wagon.
