CORIOVALLUM or CORTOVALLUM, a place in the north of Gallia, on a road from Castellum ( Cassel) to Colonia Agrippina ( Cologne), between Aduatuca ( Tongern) and Juliacum ( Juliers). The Antonine Itin. makes it 16 Gallic leagues from Aduatuca to Coriovallum, and 12 from Coriovallum to Juliacum. The distances in the Table are the same, but in the Table the name is Cortovallum or Cortovallium, as it seems. Cortovallum is perhaps the true name, as a place named Cortenseems to agree very well with the distance from Juliers, and also to preserve the ancient name.
