The Itinerary of Archbishop Baldwin through Wales: Book 2 Chapter 6. The archbishop having, by his sermon the next day, induced many persons to take the cross, we proceeded towards Banchor [Map], passing through Caernarvon [Map],¹⁴⁷ that is, the castle of Arvon; it is called Arvon, the province opposite to Mon, because it is so situated with respect to the island of Mona. Our road leading us to a steep valley,¹⁴⁸ with many broken ascents and descents, we dismounted from our horses, and proceeded on foot, rehearsing, as it were, by agreement, some experiments of our intended pilgrimage to Jerusalem. Having traversed the valley, and reached the opposite side with considerable fatigue, the archbishop, to rest himself and recover his breath, sat down on an oak which had been torn up by the violence of the winds; and relaxing into a pleasantry highly laudable in a person of his approved gravity, thus addressed his attendants: "Who amongst you, in this company, can now delight our wearied ears by whistling?" which is not easily done by people out of breath. He affirming that he could, if he thought fit, the sweet notes are heard, in an adjoining wood, of a bird, which some said was a woodpecker, and others, more correctly, an aureolus. The woodpecker is called in French, spec, and with its strong bill, perforates oak trees; the other bird in called aureolus, from the golden tints of its feathers, and at certain seasons utters a sweet whistling note instead of a song. Some persons having remarked, that the nightingale was never heard in this country, the archbishop, with a significant smile, replied, "The nightingale followed wise counsel, and never came into Wales; but we, unwise counsel, who have penetrated and gone through it." We remained that night at Banchor,¹⁴⁹ the metropolitan see of North Wales, and were well entertained by the bishop of the diocese.¹⁵⁰ On the next day, mass being celebrated by the archbishop before the high altar, the bishop of that see, at the instance of the archbishop and other persons, more importunate than persuasive, was compelled to take the cross, to the general concern of all his people of both sexes, who expressed their grief on this occasion by loud and lamentable vociferations.

Note 147. This ancient city has been recorded by a variety of names. During the time of the Romans it was called Segontium, the site of which is now called Caer Seiont, the fortress on the river Seiont, where the Setantiorum portus, and the Seteia AEstuarium of Ptolemy have also been placed. It is called, by Nennius, Caer Custent, or the city of Constantius; and Matthew of Westminster says, that about the year 1283 the body of Constantius, father of the emperor Constantine, was found there, and honourably desposited in the church by order of Edward I.

Note 148. I have searched in vain for a valley which would answer the description here given by Geraldus, and the scene of so much pleasantry to the travellers; for neither do the old or new road, from Caernarvon to Bangor, in any way correspond. But I have since been informed, that there is a valley called Nant y Garth (near the residence of Ashton Smith, Esq. at Vaenol), which terminates at about half a mile's distance from the Menai, and therefore not observable from the road; it is a serpentine ravine of more than a mile, in a direction towards the mountains, and probably that which the crusaders crossed on their journey to Bangor.

Note 149. Bangor. This cathedral church must not be confounded with the celebrated college of the same name, in Flintshire, founded by Dunod Vawr, son of Pabo, a chieftain who lived about the beginning of the sixth century, and from him called Bangor Dunod. The Bangor, i.e. the college, in Caernarvonshire, is properly called Bangor Deiniol, Bangor Vawr yn Arllechwedd, and Bangor Vawr uwch Conwy. It owes its origin to Deiniol, son of Dunod ap Pabo, a saint who lived in the early part of the sixth century, and in the year 525 founded this college at Bangor, in Caernarvonshire, over which he presided as abbot. Guy Rufus, called by our author Guianus, was at this time bishop of this see, and died in 1190.

Note 150. Guianus, or Guy Rufus, dean of Waltham, in Essex, and consecrated to this see, at Ambresbury, Wilts, in May 1177.
