At some distance from Caermarthen are several very remarkable caves: whence Merlin is supposed to have delivered his oracles.

Of Merlin and his skill what region doth not hear?
Who of a British nymph was gotten whilst she play’d
With a seducing spirit.

Drayton, Polyolbion, s. v.

Caermarthen gave birth to Merlin, who is styled, by an ancient author, “the sonne of a badde angell, or of an incubus spirit, the Britaine’s great Apollo, whom Geoffrey ap Arthur would ranke with the south-saying seer, or rather with the true prophets themselves; being none other than a meere seducer, and phantastical vizard.” He flourished in the year 480.

Some few years after this tour, I took the road to Caermarthen from Ragland, through Crickhowel, Brecon, Llandovery, and Landilo. Passing through Abergavenny, we paused for a few days at Crickhowel, where we amused ourselves in fly-fishing in the river Usk.

Crickhowel stands in the centre of a vale, scarcely surpassed by that of the Towy; and is supposed to have been built in the time of Howel Dha, about the year 940. The castle presents little to attract attention. The church contains some few ancient monuments; but the principal objects for a traveller are to be found at a short distance from the town; viz. a remarkable cave south of Langattock; a waterfall in a dingle, leading to Llanelly iron-works; the remains of a castle, on what is called the Camp Hill; and the beautiful village of Lambeter, the walks of which are, of themselves, almost worthy a journey into Wales. The society around Crickhowel is highly respectable; but there are no noblemen’s seats, and only one park within the distance of many miles. The natural scenery, however, amply compensates.

From Crickhowel we proceeded to a village, named Cwmdu, situated between two chains of mountains. The village is poor to the last degree, but the land is rich; and the valley, in which it is situated, may be called the granary of Brecknockshire. There is scarcely a field on the lower sides of the hills, that does not present a spot favourable to build upon. From the farm and house, called Cwmgû, is one of the most beautiful views in all Wales; commanding, as it does, the vale of Usk, the river winding through it, innumerable fields, a high mountain towards the north, the town of Crickhowel on the east; the ruins of Tretower below; a woody hill rising above it; and, from a field at a short distance from the house, the double head of the Beacons, towering, as it were, into the clouds.

Brecon, or Aber Honddu, is a very romantic town; with good inns, and every accommodation for a respectable family. The views around it are beautiful; the Priory groves, as a public walk, are the most delightful in all Wales, perhaps in Britain; while the castle, the priory, and other fragments of antiquity, afford ample materials for the contemplation of those who connect scenes with former events. For within the walls of the castle was planned the union of the two houses of York and Lancaster.

Passing through Trecastle, a miserable village, once a large town, possessing the ruins of a castle, we entered a valley, winding for six or eight miles at the feet of mountains, and presenting at every step something to admire, we arrived at Llandovery, or Llanymddvri, situated on the banks of the Brane, near the head of the upper vale of Towy. Here we found the remains of a small castle, once in the possession of Richarde de Pws; small in dimensions, and uninteresting in its history; but the town derives some notice from its having produced Rhys Prichard, author of a book, well known in almost every Welsh house by the name of the Vicar’s book. He sleeps here without inscription or monument.

From Llandovery the road and the Towy proceed to Llandilo through a country at once rich in fertility, and beautiful in point of scenery. Llandilo is remarkable for a battle, fought in 1281, between Edward the First and Llewellyn the Great. It has no feature in itself worthy of attention; but its environs are beautiful to the last degree.

About a mile from this town, on the road to Caermarthen, are the ruins of Dinevawr Castle, the most celebrated spot in the principality. This castle was erected by Roderique the Great in the year 877. So much have been written of these ruins, of the noble park, belonging to Lord Dynevor, and the country round, that I shall merely observe, that, after passing a few hours in admiration, we passed on to Grongar Hill, and sate beneath the hawthorn, under which Dyer is supposed to have written his beautiful poem. I cannot, however, refrain from quoting a passage from Spenser, where he describes the Cave of Merlin, which he places near the rocks of Dinevawr.
