The Roman Map of Britain Varis or Vario St Asaph, or Veratino? Ruthin

Veratino (R&C 87) next

Varis (AI 482₇ Iter xi) not necessarily the same

    Veratino cannot be connected by road to Lutudaron (R&C 88), it would have to be between Carsington and Buxton. If there is any credibility to my theory of the Cosmographer's methodology, then Veratino must be connected by road to the previous entry Deva Chester (R&C 86). Varis, traditionally St. Asaph (SJ0374), bears a resemblance to Veratino. The form of Veratino can be explained as Varis or Vario read as Várîo and expanded to Veratino. Bod Fari (SJ0971), also on the Clwyd Afon Clywedog, appears to preserve the name. It is Potvary on Blaeu's Map of Denbigh and Flint 1645. Varis may represent the old name of the Clwyd. identical to Farrar Varar aestuarium. 
    Other than St. Asaph, the notable presences are Ffridd (sj2854), Ruthin (sj1058), and Prestatyn (sj0682). Ruthin is both on the Clwyd and connected by road to Chester, so there remains the possibility that the Cosmography's entry represents a different site on the Clwyd at Ruthin sharing the river name element *uar- 'water'. Veratino's form may represent a corrupted Varantia, Verentia, Varenna or other similar European form. See PNRB p.486.

Veratino is in no way connected with Vernemeto Willoughby-on-the-Wolds.
