We're still in Tarquinia and we visit the tomb of Aninas. We gain some insight into the alphabet the Etruscans used, allowing us to recognize some names, but unfortunately, they didn't leave much in the way of writings to allow us to know much more.

We get a look at the tomb, in terracotta, of a noblewoman. The clay allows for detail, where tombs in Macco do not. We then go to Rome, to the most important Etruscan museum, where we see once again, what an important role the afterlife played in the lives (and deaths) of the Etruscans.

The Etruscans were influenced by other ethnic groups, particularly the Greeks. On display in the National Etruscan Museum of Villa Giulia, we find evidence of this in the terracotta objects and fine gold jewelry and precious objects dating from the period.

With a look at one of the greatest Etruscan masterpieces in the Villa Giulia museum, we take our leave of Rome to journey to the Umbrian city of Assisi, or, as it was called in Roman times, Assisium.

We're in Assisi, where, during some excavations, a domus was discovered. It's clear it belonged to a wealthy family because of the richness of the wall and floor decorations, and might even have been the home of the poet Propertius.

Parking is a problem in medieval hilltop towns and cities (especially those attractive to tourists), so one solution is to build an elevator to get from parking further down the hill, up to the center of town. But, you never know what you are going to find when excavating. In Assisi, they certainly hit the jackpot, right in the center of town: A roman domus.

If you have ever visited Italy, you have probably run across the term pinacoteca describing a picture gallery, and wondered where it came from. You will find out in this video about a room called the "tablinum" in the Assisi domus, discovered because they wanted to build an elevator!

Ancient culture merged with "modern" culture, especially after Constantine created the new capital of the Roman Empire, Constantinople. Near Matera in Basilicata, even caves built into the rock face became churches. The frescoes on those walls are quite stunning.

Nature offers us some extraordinary wonders, and this time, Alberto Angela takes us to the Frassassi Caves, in the Marches region, and explains what the caves were used for by prehistoric man.

Alberto Angela brings us to the Ancona Abyss, an immense cave chamber in the Natural Regional Park of Gola della Rossa and Frasassi in the Marches region. The spectacular Ancona Abyss and other innermost caves in the Frasassi cave system were only discovered in 1971.

Alberto Angela tells us how these natural wonders were discovered by a group of young cave explorers from the nearby city of Ancona.

Alberto Angela describes the discovery of the Ancona Abyss, named after the city the speleologists were from. It’s part of the Great Wind Cave.

The magical Frasassi caves look like something out of a fairy tale, but there's a more scientific explanation.

Alberto Angela tells us how these caves and their internal structures were created. The key is something very simple. Water.

We spend some more time in the spectacular Frasassi Caves, and this time we see the famous "Room of the Candles" filled with stalagmites that look like candles ready to be lit. Alberto Angela also discusses the colors in this place, as well as the "sounds of silence."
