In classical antiquity, the Triboci or Tribocci were a Germanic people of eastern Gaul, inhabiting much of what is now Alsace.
[6] D'Anville supposes that the territory of the Tribocci corresponded to the mediaeval diocese of Strasbourg.
Consequently, a Tribocci burial ground was excavated in Diersheim on the right bank of the Rhine in today's Germany.http://dl.ub.uni-freiburg.de/diglit/ortenau1977/0011/ocr?sid=9959984406c34fcd88a0a3f26001cbdf Saletio (Seltz), we may suppose, belonged to the Nemetes, as in modern times it belonged to the diocese of Speyer; and it is near the northern limits of the diocese of Strasbourg.
On the south towards the Rauraci, a place named Marckolsheim, on the southern limit of the diocese of Strasbourg and bordering on that of Basel, indicates a boundary by a Teutonic name (mark), as fines does in those parts of Gaul where the Roman tongue prevailed.
[12] The Triboci joined the revolt of Civilis in 70 CE, sending reinforcements to the Treveran rebel commander Julius Tutor along with the Caeracates, Vangiones and dissident Romans.
