Campanian
The Campanian is, in the ICS' geologic timescale, the fifth of six ages of the Late Cretaceous epoch (or, in chronostratigraphy: the fifth of six stages in the Upper Cretaceous series). The Campanian spans the time from 83.6 ± 0.7 Ma to 72.1 ± 0.6 Ma (million years ago). It is preceded by the Santonian and it is followed by the Maastrichtian.
Capena
Ancient Capena seems to have been ruthlessly sacked by the Romans sometime around 390 BC, following a long campaign of resistance by the Capenates to the ever-growing influence of Rome in the area. The settlement continued to exist until the collapse of the Western Roman Empire, after which all traces of it were lost. It was not until the pioneering work of Pierluigi Galletti in the mid-18th century that Capena’s former location was decisively identified. Even then, it took more than a hundred years for other historians to reach a consensus that Galletti had been correct.
