 Morgan suggests Emsanternon as a mixture of both Bradney's and Osbourne and Hobbs understanding where Ynys is elevated to a ‘raised area in a water-meadow’, while Teyrnon is reduced to Teyrn meaning ‘prince’.Morgan points out that it was not until 1272 that the Latinised Lanterna was instructed to be used in the official lists by the Cistercian General Chapter rather than Vallium which had been recorded in 1244.Vallium is proposed as ‘spurious’ which could have been derived from a misinterpretation of Carlium [Caerleon].
