CRODUNUM a place in the Gallia Provincia, mentioned by Cicero (Cic. Font. 100.4). There is no indication of its site except what may be derived from this corrupt passage of Cicero. A duty (portorium) was levied on wine carried from Narbonneto Toulouse, and it was levied at Cobiomachum, which was between these two places. If the merchants avoided Cobiomachum, they were caught either at Crodunum or Vulchalo; which we must assume to be places that a man must go through to reach Toulousefrom Narbonne, if he avoided Cobiomachum. This is all that we know; and yet people will tell us what is the modern site of Crodunum.
