Causennis
Causennis in Britain, mentioned in the 5th Itinerary, the difficulties of which are noticed under COLONIA and DUROBRIVIS. Being the first station south of Lindum, from which it is distant 12 miles, and Lindum (Lincoln) being one of the most certain identifications we have, it is safe to prefer An-caster to Boston, Nottingham, and other localities as its present equivalent. The termination -caster, the present existence of Roman remains, and even the syllable An ( == caus-Ennae castra) all support this view. Besides which it stands upon the Cliff Road, which is a Roman one.
