28. That highest authority, the great Julius, informs us that Gaul was once more powerful than Germany. Consequently we may believe that Gauls even crossed over into Germany. For what a trifling obstacle would a river be to the various tribes, as they grew in strength and wished to possess in exchange settlements which were still open to all, and not partitioned among powerful monarchies! Accordingly the country between the Hercynian forest and the rivers Rhine and Moenus, and that which lies beyond, was occupied respectively by the Helvetii and Boii, both tribes of Gaul. The name Boiemum still survives, marking the old tradition of the place, though the population has been changed. Whether however the Aravisci migrated into Pannonia from the Osi, a German race, or whether the Osi came from the Aravisci into Germany, as both nations still retain he same language, institutions, and customs, is a doubtful matter; for as they were once equally poor and equally free, either bank had the same attractions, the same drawbacks. The Treveri and Nervii are even eager in their claims of a German origin, thinking that the glory of this descent distinguishes them from the uniform level of Gallic effeminacy. The Rhine bank itself is occupied by tribes unquestionably German, -- the Vangiones, the Triboci, and the Nemetes. Nor do even the Ubii, though they have earned the distinction of being a Roman colony, and prefer to be called Agrippinenses, from the name of their founder, blush to own their origin. Having crossed the sea in former days, and given proof of their allegiance, they were settled on the Rhine-bank itself, as those who might guard it but need not be watched.
