We move from Umbria to Tuscany and visit the evocative ruins of the abbey of San Galgano. Next will be Pisa, a prime example of how Tuscany, in medieval times, was experimenting with very "modern" ideas.

During the reception, Adriano manages to find a quiet moment to tell us what a Polish wedding is all about. He also talks about love, the main focus of this special day.

Alberto Angela points out how realistic Giotto's frescoes are compared to earlier ones. He also mentions the important fact that Saint Francis composed one of the first poems in the vernacular

Adriano and Anita exchange wedding vows on this special day for them.

We move from the lower basilica to the upper one, which has an entirely different feel to it. Here, we are surrounded by a show of light and color in colorful frescoes and stained-glass windows.

It's a very special day for Adriano and Anita. We hear Adriano's mother read a famous passage on love from First Corinthians 13 (New Testament of the Bible).

What did Saint Francis look like? There are clues in a fresco in the lower basilica of the church dedicated to him in Assisi.

People often wonder how the Basilica of St. Francis could be as imposing and rich as it is, when the saint to whom it is dedicated had taken an oath of poverty. Alberto Angela explains this and other contradictions.

This episode will take us to Umbria. We start with one of the most beautiful cities in the region, Assisi, a city that's practically synonymous with the Franciscan monastic order and its founder, Saint Francis.

Falling in love doesn't follow scientific rules. Silvana and Luciano tell us about how they met and their plans, now that they are of a certain age.

Franco shows us some infused salts that we would never think of off hand. His descriptions are colorful and make us want to try out these delicacies.

Two geniuses left their indelible marks on civilization: Leonardo with the Last Supper and Michelangelo with his David.

This fascinating segment is all about salt: Our spice journey takes us to Sicily, where much of Italy's salt is harvested. Franco talks about how salt is life, salt is gold.

We look at Leonardo's Last Supper from close up — the details, the symbolism — but also from the refectory floor, seeing how Leonardo's genius made the fresco part of the room itself.

When you blend spices from exotic places, you are a kind of magician. A pinch of this or a pinch of that can make all the difference.
