These are marked by no special characteristics, excepting the common worship of the goddess Nerthum, or Mother Earth, of whom they believe that she not only intervenes in human affairs, but also visits the nations. In a certain island of the sea is a wood called Castum. Here is kept a chariot sacred to the goddess, covered with a curtain, and permitted to be touched only by her priest, who perceives her whenever she enters the holy vehicle, and with deepest veneration attends the motion of the chariot, which is always drawn by yoked cows. Till the same priests re-conducts the goddess to her shrine, after she has grown weary of intercourse with mortals, feasts and games are held with great rejoicings, no arms are touched, and none go to war. Slaves wash the chariot and curtains in a sacred lake, and, if you will believe it, the goddess herself; and forthwith these unfortunate beings are doomed to be swallowed up in the same lake. This portion of the Suevian territory stretches to the centre of Germany. Next adjoining is the district of the Hermunduri (I am now following the course of the Danube as I previously did that of the Rhine), a tribe faithful to the Romans. To them, accordingly, alone of all the Germans, is commerce permitted. They travel everywhere at their own discretion. When to others we show nothing more than our arms and our encampments, to this people we open our houses, as to men who are not longing to possess them. The Elbe rises in the territory of the Hermunduri. _VI.--The Tribes of the Frontier_ Near the Hermunduri reside the Narisci, and next the Marcomanni and the Quadi, the former being the more famed for strength and bravery, for it was by force that they acquired their location, expelling from it the Boii. Now, here is, as it were, the frontier of Germany, as far as it is washed by the Danube. Not less powerful are several tribes whose territories enclose the lands of those just named--the Marsigni, the Gothini, the Osi, and the Burii. The Marsigni in speech and dress resemble the Suevi; but as the Gothini speak Gallic, and the Osi the Pannonian language, and as they endure the imposition of tribute, it is manifest that neither of these peoples are Germans. Upon them, as aliens, tribute is imposed, partly by the Sarmatæ, partly by the Quadi, and, to deepen their disgrace, the Gothini are forced to labour in the iron mines. Little level country is possessed by all these several tribes, for they are located among mountainous forest regions, Suevia being parted by a continuous range of mountains, beyond which live many nations. Of these, the most numerous and widely spread are the Lygii. Among others, the most powerful are the Arii, the Helveconæ, the Manimi, the Elysii, and the Naharvali.
