Via degli Dei
From the 7th to the 4th century B.C. the Etruscans used to follow an ancient road that connected Fiesole to Felsina in order to develop their trade and extend their dominion over the Po Valley.
Then the Romans founded the colony of Bononia on the remains of the ancient Felsina in 189 BC; therefore, Arezzo had to be connected to Rome through the Apennines. Two years later, they built a real trans-Apennine road called “the Flaminia Military Road” which retraced the original Etruscan route.
During the Middle Ages this ancient route continued to represent the easiest way to cross the Apennines. The original Roman paving soon fell into disuse and was submerged by vegetation; it was replaced by a narrow mule track without paving used by travelers on foot or on horseback.
The Via degli Dei route was created by a group of Bolognese hikers in the late 20th century.
Why is it called Via degli Dei?
Because the route passes through places that are named after the Gods of Roman mythology such as Monte Adone, Monzuno (Mons Iovis, Iovis was the Roman God of the sky and thunder), Monte Venere, Monte Luario (Lua was the Roman Goddess of atonement).
Today the Via degli Dei is one of the main tourist attractions of the Apennines: the entire route from Bologna to Florence can be achieved in four/six days on foot or in two/three days by bike (depending on people's skills).
