| Administrative History | "I cannot more effectively convey to my readers a clear notion of the arrangement and succession of the strata in Brecknockshire and the adjacent counties of Radnor and Caemarthen, than by annexing a semi-panoramic view, taken by Mrs Traherne, from the mountain of Esgair davydd, south-west of Llanwrtyd. The spectator is placed on the old slaty rocks of the Cambrian System, and looking E.N.E. and S.E., his range of vision embraces the outlines of two great systems which it is my object to illustrate. In the distance is the Old Red Sandstone, occupying the highest mountains of South Wales, and in the middle ground the Silurian System, appearing prominently in the escarpment of Mynidd Epynt, whence it extends north-eastward to Radnor Forest, and south-westward into the hills near Llandovery. The valley in which the Yrfon and the Wye meander, through beds of soft schist and shale, is well expressed by the artist...." Murchison, R, Silurian System', (1839), p345-346. |
