TARODU´NUM(Ταρόδουνον), a town in the south-west of Germany between Mons Abnoba and the Rhenus. (Ptol. 2.11.30.) It is universally identified with Mark Zartennear Freiburgin the Breisgau, which, down to the 8th century, bore the name of Zarduna, a name which is formed from Tarodunum in the same way in which Zabernis formed from Tabernae.
