Thomas Surridge, Notices by the Rev. T. Surridge… (1853)
“ According to the authority of Camden, Morpeth was the Roman Corstopitum, and according to the itinerary, the distance from Bremenium to Corstopitum was twenty Roman miles, equal to a little more than eighteen English miles, or the present distance of Risingham from Morpeth exactly. Besides, the portal inscription found at Risingham shows it to have been a station of some importance, and its sheltered situation would induce the supposition that it was, in all likelihood, selected for the head quarters of the Roman Army, and the residence of the Court. ”
