Roman antiquite: the bag of Rome of 390 BC as a result of the victory of the Gauls Senons led by Brennus over the Roman troops at the Battle of the Allia; a military success allowing them to invest the city and demand from the defeated Romans the payment of a heavy grudge - the flight of the vestals that were put to safety in Caere; an etruscan city. neighbour and friend of Rome; and were thus epargnees during the Sack of Rome of 390 BC after Battle of the Allia fought between the Senones (one of the Gallic tribes which had invaded northern Italy) and the Romans - the vestals leaving Rome for Caere; safe etruscan city) Engraving from ??Storia di Roma??by Francesco Bertolini
