Commenting on one of the prose tracts from the dindshenehas, Conor Newman quotes Edel Bhreathnach (1995) that the "Dindgnai Temraeh 'is so detailed that it is tantamount to a medieval survey of the Hill of Tara.' How this bears on the historicity of these accounts is a question more for the historian than the archaeologist but has prompted us to take an optimistic view of the integrity and usefulness of the topographical information in the dindshenehas."

A half century after O'Donovan and Petrie's work, a less comprehensive survey was compiled by the Rev. Denis Murphy and Thomas J. Westropp (1894). In the early 1900s further field work was completed by R.A.S. Macalister (1919; 1931; 1938-56). (Roche, Helen, et. al., "Excavations at Raith na Rig, Tara, Co. Meath, 1997."
