[150] W. F. Wakeman states that at one time this slab was in the possession of Petrie, the well-known antiquary. An engraving of a chess-board of the fourteenth century shows but 42 squares, 7 × 6.

Wakeman offers a suggestion in connection with the name Balhu; he states that Joyce in his _Irish Names of Places_ translates the name of the Fermanagh town of Lisbellaw, _Lis-bel-atha, the lis of the ford mouth_. Now, there was no river ever there, consequently there could be no “ford mouth.” There is certainly a _lis_ or ford in the neighbourhood, but the little stream which now drives the woollen mill of Lisbellaw flows through a deep cutting communicating with Loch Eyes, and which was made only in recent times. The _natural_ outlet from the loch ran, and still runs, in a northerly direction, and cannot have influenced the naming of Lisbellaw, as its course commences at a distance of some miles from the village. “The name Lisbellaw seems to invite investigation. Could it be translated ‘the fort or lis of Balhu,’ even as Dunleary is ‘the fort or dun of Laighaire’”? [156] _Journal Royal Hist. and Arch. Asso. of Ireland_, vol. v. (New Series), p. 229.
