The range of the Clwydian Hills to the east is in several places surmounted by camps, that have been occupied by succeeding peoples, for in some are found flint weapons, bronze, later Roman ware and coins, and even mediæval pottery. The highest point is Moel Famma. Moel Fenlli is the nearest to Ruthin, and takes its name from Benlli, king of Powys, who was supplanted by Cadell Deyrnllwg. He is reported to have retired to this stronghold. The story is this. Germanus--not, I hold, the Bishop of Auxerre, but his namesake, a nephew of S. Patrick, and finally Bishop of Man--was in western Britain. He came to Pengwern or Shrewsbury, and asked to be admitted. But Benlli refused, and Germanus was forced to spend the night outside the walls. A servant of Benlli, named Cadell, disregarding his master’s orders, furnished the saint and his party with food. According to the legend, fire fell from heaven and consumed the town, and Benlli escaped with difficulty. Then Germanus set up Cadell to be king of Powys in his room. What seems actually to have happened was that Benlli, with the pagan party, clung to the side of Vortigern, and Germanus, stirred up Cadell, a petty prince of Powys, against him, and that Pengwern was taken, and Cadell elevated to be king in the room of Benlli. Legend has been busy with the deposed king. It is said that in his camp he suffered tortures from rheumatism and wild-fire, and that he sought relief from S. Cynhafal, patron of Llangynhafal hard by, who refused it to him, as he was a renegade to paganism. Then Benlli in his pain sought ease in the cooling waters of the River Alun, but the stream likewise refused its aid, and dived underground. Again Benlli plunged in, and the water dived again. He tried a third time, and the river a third time retreated below the surface. The story has been invented to explain the fact that the Alun actually does thrice disappear in its bed. At Derwen, in the church, there is a good screen, but the finest of all in this district is that of Llanrwst. In most of the Welsh screens the openings are rectangular, with some dainty tracery introduced at the top. But at Llanrwst the openings are pointed. In the Devon and Cornish and Somersetshire screens these openings are mere Perpendicular windows, and all in each screen are alike in tracery, and this tracery is very much the same in all. But at Llanrwst the design in each window of the screen is different; there are, however, no mullions. The face of the rood-loft is also rich, and only needs the filling in of the niches with figures to make it complete. Llandegla is interesting only on account of its spring, now all but choked up, on Gwern Degla, about two hundred yards from the church. Pennant in his _Tours_ writes:--
