The Notitia mentions the Cortoriacenses as under the command of the general of the cavalry in the Galliae. The Cortoriacenses imply a place Cortoriacum, which was afterwards written Curtricum, and is now Courtrai,
in the Belgian province of West Flanders.
In the Capitularies of Charles the Bold, A.D. 853, the Pagus Curtricisus is mentioned between “Adertisus et Flandra.” The Flemish name of Courtrai is Cortryk.
