My fleet sailed from the mouth of the Rhine eastward as far as the lands of the Cimbri, to which, up to that time, no Roman had ever penetrated either by land or by sea, and the Cimbri and Charydes and Semnones and other peoples of the Germans of that same region through their envoys sought my friendship and that of the Roman people.
The contemporary Greek geographer Strabo testifies that the Cimbri still existed as a Germanic tribe, presumably in the "Cimbric peninsula" (since they are said to live by the North Sea and to have paid tribute to Augustus):
As for the Cimbri, some things that are told about them are incorrect and others are extremely improbable. For instance, one could not accept such a reason for their having become a wandering and piratical folk as this that while they were dwelling on a Peninsula they were driven out of their habitations by a great flood-tide; for in fact they still hold the country which they held in earlier times; and they sent as a present to Augustus the most sacred kettle in their country, with a plea for his friendship and for an amnesty of their earlier offences, and when their petition was granted they set sail for home; and it is ridiculous to suppose that they departed from their homes because they were incensed on account of a phenomenon that is natural and eternal, occurring twice every day. And the assertion that an excessive flood-tide once occurred looks like a fabrication, for when the ocean is affected in this way it is subject to increases and diminutions, but these are regulated and periodical.[3]
