It was in the year 990 A.D. that Sigerico [with the accent on the third syllable], Archbishop of Canterbury, undertook a journey to Rome and back. The route that he took to return to Canterbury, and of which he wrote in his diary, is the road system that has passed to history with the name of the Via Francigena. And in this book we will speak of this important thoroughfare, which was a veritable communications axis between Rome and the rest of Europe. Or, rather, we shall speak about it by limiting ourselves to the Tuscan segment. In this book is described the historic-temporal evolution in the ways of eating, from the medieval period on, to then arrive across the Renaissance and the 18th century at the Unity of Italy and down to our days. This is an ambitious objective, indeed almost a desire to relate a certain history through food, because its evolution, which results in the concept of gastronomy, cannot fail to feel the influence of the influxes of the times in which it was practiced.
