Note 34a — Chapter II · JOURNEY THROUGH HAY AND BRECHEINIA

The first of these are now styled the Black Mountains, of which the Gadair Fawr is the principal, and is only secondary to the Van in height. The Black Mountains are an extensive range of hills rising to the east of Talgarth, in the several parishes of Talgarth, Llaneliew, and Llanigorn, in the county of Brecknock, and connected with the heights of Ewyas. The most elevated point is called Y Gadair, and, excepting the Brecknock Van (the Cadair Arthur of Giraldus), is esteemed the highest mountain in South Wales. The mountains of Ewyas are those now called the Hatterel Hills, rising above the monastery of Llanthoni, and joining the Black Mountains of Talgarth at Capel y Ffin, or the chapel upon the boundary, near which the counties of Hereford, Brecknock, and Monmouth form a point of union. But English writers have generally confounded all distinction, calling them indiscriminately the Black Mountains, or the Hatterel Hills.
