and "appears not to have had the chisel, or any inscription upon it." "The craig (he adds) or steep rocky mountain which forms the northern extremity of the Pentland Hills, and makes a conspicuous figure at Edinburgh, hangs over this field of battle. It is called Caer-_Ket_an Craig. This name appears to be derived from the Ket-stane above described, and the fortified camp adjacent, which, in the old British, was termed a Caer." (P. 611.)] [Footnote 205: See "Annales Cambriae," in the _Monumenta Hist. Britannica_, p. 833.] [Footnote 206: In Maitland's time (1753), there was a farm-house termed "Catstean," standing near the monument we are describing. And up to the beginning of the present century the property or farm on the opposite side of the Almond, above Caerlowrie, was designated by a name, having apparently the Celtic "battle" noun as a prefix in its composition--viz., Cat-elbock. This fine old Celtic name has latterly been changed for the degenerate and unmeaning term Almond-hill.] [Footnote 207: _Historia Ecclesiast._, lib. i. c. xii. "Sermone Pictorum Peanfahel, lingua autem Anglorum Penneltun appellatur."] [Footnote 208: _Historia Britonum_, c. xix. At one time I fancied it possible that the mutilated and enigmatical remains of ancient Welsh poetry furnished us with a name for the Cat-stane older still than that appellation itself. Among the fragments of old Welsh historical poems ascribed to Taliesin, one of the best known is that on the battle of Gwen-Ystrad. In this composition the poet describes, from professedly personal observation, the feats at the above battle of the army of his friend and great patron, Urien, King of Rheged, who was subsequently killed at the siege of Medcaut, or Lindisfarne, about A.D. 572. Villemarque places the battle of Gwen-Ystrad between A.D. 547 and A.D. 560. The British kingdom of Rheged, over which Urien ruled, is by some authorities considered as the old British or Welsh kingdom of Cumbria, or Cumberland; but, according to others, it must have been situated further northwards. In the poem of the battle of Gwen-Ystrad (see the _Myvyrian Archaeology_, vol. i. p. 53), Urien defeats the enemy--apparently the Saxons or Angles--under Ida, King of Bernicia. In one line near the end of the poem, Taliesin describes Urien as attacking his foes "by the white stone of Galysten:" "Pan amwyth ai alon yn Llech wen Galysten."
