DITA´TTIUM(Διττάτιον) is one of the cities. of the Sequani, in Gallia, which Ptolemy mentions (2.9); and he places it before Vesontio ( Besançon). There is nothing to show the site, except Ptolemy's position, which is useless. D'Anville thinks that Ditattium may be a place called Cité, where there are some remains, not far from Passavant. Some geographers place Ditattium at Doleon the Doubs;others again identify Ditattium with the ruins on the hill of Vieux Seurre, about a league SW. of Seurre. All this is mere guess, and a sample of trifling; for there is nothing at all to determine the question.
