(Antonine), a town of Switzerland, supposed to be the modern Pfim, in the north of the district of Turgow, on the rivulet Thur, not far from the borders of Suabia, about half way between Constance and Frauenfeld. So called, because when Cæcina, general of the emperor Vitellius, with the auxiliary Rhetians, defeated the Helvetii, the former extended their borders thus far, their territory ending here; and in the time of the Romans, it was the last town in this quarter, and of some repute.
