To the north of Latinum, the Italic tribe of the Umbri settled, ruling across the Appennine slopes of the Adriatic for centuries. They stretch between the Tiber and Nar rivers, creating dozens of small settlements in the area. The Latins viewed them as among the oldest in Italy, believed to have been called Ombrii (here, "the people of the thunderstorm," after ὅμβρος, "thunderstorm") by the Greeks because they survived the deluge (literally "the inundation of the lands by thunderstorms, imbribus), or the infamous Greek flood myths of old.
