The Itinerary of Archbishop Baldwin through Wales: Book 2 Chapter 6. We continued our journey over the Traeth Mawr [Map],¹⁴¹ and Traeth Bachan,¹⁴² that is, the greater and the smaller arm of the sea, where two stone castles have newly been erected; one called Deudraeth [Map], belonging to the sons of Conan, situated in Evionyth, towards the northern mountains; the other named Carn Madryn, the property of the sons of Owen, built on the other side of the river towards the sea, on the head-land Lleyn.¹⁴³ Traeth, in the Welsh language, signifies a tract of sand flooded by the tides, and left bare when the sea ebbs. We had before passed over the noted rivers, the Dissenith,¹⁴⁴ between the Maw and Traeth Mawr, and the Arthro, between the Traeth Mawr and Traeth Bachan. We slept that night at Nevyn, on the eve of Palm Sunday, where the archdeacon, after long inquiry and research, is said to have found Merlin Sylvestris.¹⁴⁵

Note 141. The Traeth Mawr, or the large sands, are occasioned by a variety of springs and rivers which flow from the Snowdon mountains, and, uniting their streams, form an aestuary below Pont Aberglaslyn.

Note 142. The Traeth Bychan, or the small sands, are chiefly formed by the river which runs down the beautiful vale of Festiniog to Maentwrog and Tan y bwlch, near which place it becomes navigable. Over each of these sands the road leads from Merionyth into Caernarvonshire.

Note 143. Lleyn, the Canganorum promontorium of Ptolemy, was an extensive hundred containing three comots, and comprehending that long neck of land between Caernarvon and Cardigan bays. Leland says, "Al Lene is as it were a pointe into the se."

Note 144. In mentioning the rivers which the missionaries had lately crossed, our author has been guilty of a great topographical error in placing the river Dissennith between the Maw and Traeth Mawr, as also in placing the Arthro between the Traeth Mawr and Traeth Bychan, as a glance at a map will shew.

Note 145. To two personages of this name the gift of prophecy was anciently attributed: one was called Ambrosius, the other Sylvestris; the latter here mentioned (and whose works Giraldus, after a long research, found at Nefyn) was, according to the story, the son of Morvryn, and generally called Merddin Wyllt, or Merddin the Wild. He is pretended to have flourished about the middle of the sixth century, and ranked with Merddin Emrys and Taliesin, under the appellation of the three principal bards of the Isle of Britain.

1911 Encyclopædia Britannica. Sep 1811 to Feb 1813. [Percy Bysshe Shelley] ... sailed thence to Dublin, where Shelley was eager, and in some degree prominent, in the good cause of Catholic emancipation, conjoined with repeal of the union; crossed to Wales, and lived at Nant-Gwillt, near Rhayader, then at Lynmouth [Map] in Devonshire, then at Tanyrallt in Carnarvonshire. All this was between September 1811 and February 1813. At Lynmouth an Irish servant of Shelley's was sentenced to six months' imprisonment for distributing and posting up printed papers, bearing no printer's name, of an inflammatory or seditious tendency - being a Declaration of Rights composed by the youthful reformer, and some verses of his named The Devil's Walk. At Tanyrallt Shelley was (according to his own and Harriet's account, confirmed by the evidence of Miss Westbrook, the elder sister, who continued an inmate in most of their homes) attacked on the night of 26th February by an assassin who fired three pistol-shots. It was either a human assassin or (as Shelley once said) " the devil." The motive of the attack was undefined; the fact of its occurrence was generally disbelieved, both at the time and by subsequent inquirers. Shelley was full of wild unpractical notions; he dosed himself occasionally with laudanum as a palliative to spasmodic pains; he was given to strange assertions and romancing narratives (several of which might properly be specified here but for want of space), and was not incapable of conscious fibbing. His mind no doubt oscillated at times along the line which divides sanity from insane delusion. It is now, however, at last proved that he did not invent such a monstrous story to serve a purpose. The Century Magazine for October 1905 contained an article entitled "A Strange Adventure of Shelley's," by Margaret L. Croft, which shows that a shepherd close to Tanyrallt, named Robin Pant Evan, being irritated by some well-meant acts of Shelley in terminating the lives of dying or diseased sheep, did really combine with two other shepherds to scare the poet, and Evan was the person who played the part of "assassin." He himself avowed as much to members of a family, Greaves, who were living at Tanyrallt between 1847 and 1865. This was the break-up of the residence of the Shelleys at Tanyrallt; they revisited Ireland, and then settled for a while in London.
