From Tibv mouth the shore gently giveth back, and openeth for itself the passage of many riverets, among which in the upper part of this shire Stuccia, whereof Ptolomee maketh mention, is most memorable, whenas the name of it continueth after a sort whole at this day, being called in common speach Ystwith: at the head whereof are veines of lead, and at the mouth the towne Aber-y-stwith, the most populous and plentuous place of the whole shire, which that noble Gilbert de Clare also fensed with walles, and Walter Bec an Englishman defended a great while against the Welsh right manfully. Hard hereunto lieth Lhan Badern vaur, that is, The Church of Patern the Great, who being borne in little Britaine, as we read in his life, both governed the Church by feeding, and fed it by governing. Unto whose memorie the posterity consecrated heere as well a church, as also an Episcopall see. But the Bishoprick, as Roger Hoveden writeth, quite decayed many yeares since when the people had wickedly slaine their pastour. At the same mouth also the river Ridol dischargeth it self into the Irish sea. This river, descending out of Plinlimon, an exceeding steepe and high hill that encloseth the North part of this shire, and powreth out of his lap those most noble rivers Severn and Wy, whereof I have already often spoken. And not much above Y-stwith mouth the river Dev, that serveth in steed of a limite betweene this and Merionithshire, is lodged also within the sea.
