While modern sources state the height of the stone to be 2 m (6.6 ft), older writers such as Frazer and Petrie wrote of it as being up to a meter taller. It is unclear what would explain the discrepancy. Has the stone sunk into the waterlogged ground? Has the bog grown up at its base? Or has the top part of the stone been somehow removed?

Letter, to Lieut. Thomas A. Larcom, Superintendent of the Ordnance Survey, from George Petrie, head of the Survey's Topographical Section, written from Rathcarrick, Co. Sligo, concerning his examination of sites of archaeological interest in the county, with particular reference to the 'sepulchral circles' and cromleacs at Carrowmore, Kilmacowen, Co. Sligo. 12 August 1837.
William Wakeman wrote of the Tobernaveen Stone, "Unquestionably some of the holed-stones are of doubtful character, inasmuch as they may be classified either as prehistoric, or belonging to an early period of Christianity. We may perhaps assign to one of the finest monuments of this class remaining in Ireland a degree of antiquity equal at least to that acknowledged to be possessed by the cromlechs, circles, and other megaliths of Carrowmore, immediately adjoining." (Wakeman, William F., and John Cooke. Wakeman's Handbook of Irish Antiquities. Dublin: Hodges, Figgis, 1903. 18-19.)

"Through this stone babies were passed to ward off the many infant maladies that for so many centuries afflicted Ireland with a child mortality greater than almost anywhere else in Europe."

As an example of the medicinal efficacy associated with prehistoric tombs, Grinsell writes of "The activities of Dr. Toope of Marlborough (c. 1670) in concocting medicines from human bones dug up at the Sanctuary or barrows near it, and at the West Kennet long barrow in Wiltshire."
Author Thomas Keith describes this recourse to magic as being resorted to by earlier cultures "to explain misfortune and to mitigate its rigor." (Thomas, Keith. Religion and the Decline of Magic. New York: Charles Scribner's Sons, 1971. 21.)

7The well which makes the trip to the stone so difficult, Tobar na bhFian (the Well of the Warriors) provided the ancient name of the townland, Tobernaveen. One blogger was aided in his trip to the stone by a villager who provided a plank to be deployed as a bridge.
