Illtud Cross
A funny thing happens every time I write something about Illtud the magister militum/princeps militum/terriblis miles as Uther Pendragon: the hit number on that particular blog post climbs far higher than for any articles touching on other Arthurian subjects.
Having just offered this piece -
- I heard from a reader who was disappointed I refused to accept Illtud as Arthur's father. I am going to quote directly from this reader, unedited and with her permission:
"Dear Mr. Hunt: Is there any way you can make Illtud/Uther work? It seems to be you have proven the true identity of Uther Pendragon. As he is the only father we know of for the Arthur of 5th-5th centuries AD, what do we do without him? Without meaning any disrespect (your work is awesome!), it seems to me that if we don't have a father for Arthur then we don't have Arthur. Or at least we don't know where he comes from and that pretty much leaves us having to resort to theories like the one you've recently flushed out for Lucius Artorius Castus. In other words, we are forced to go to someone, anyone who is provably historical. But worse, Uther becomes just another lie of Geoffrey of Monmouth and that casts in doubt the whole idea that there really was a Dark Age hero. Isn't it possible that there was an Arthur son of Illtud, maybe for Badon and Camlan, and that it is all the other battles that were merely attached to him later to enhance his story? I don't know; maybe the other battles do belong to Castus. Or to Castus and Arthur son of Aedan. If you could find a way to keep Illtud AND tell us how the later Arthurs in the Irish-descended British kingdoms of Dyfed and Dalriada came to be, wouldn't that be wonderful?"
Sigh. To be honest, I'm not sure what to do with this. But it has been bothering me for days. I've tried to shake it and just can't. So... let me try to get my mind around this problem one last time and, hopefully, produce something coherent that might help us with what I'm going to start calling "The Illtud Problem."
The first thing for me to do, I suppose, is to admit that, yes, I do think Uther = Illtud.
The next thing to do was to find Illtud's Llydaw - WHICH IS NOT ARMORICA/BRITTANY.
For a Llydaw that appears to have been inside Britain, here is a discussion of the place-name from P. C. Bartram's A WELSH CLASSICAL DICTIONARY:
LLYDAW.
The place-name appears in old Welsh as Lettau in the Life of St.Cadog (§35) here identified
with Armorica and also (§45) used for the immigrants to Gaul under Maximus: gens que vocatur Lettau,
glossed Brittones. The Irish form was Letha which is found applied not only to Armorica but also to
Latium (John Rhys, Celtic Folklore, p.532). The Latinised form of the name was Letavia (e.g. the
Breton Life of Gildas; §16, the Life of St.Illtud, §1 etc.). An inhabitant was called Lledewig, ‘Letavian’
(See Eneas Ledewig, Glythmyr Ledewig), plural Lledewigion, older Letewicion (HB §27 MS.C),
Lidwicc(i)um, Lidwicingum [oblique case] in ASC s.aa. 885(6), 915(8). A.W.Wade-Evans spelt
Llydewig (WCO 163, 198). See also s.n. Cynan ab Eudaf.
Llydaw is the regular Welsh name for Armorica, Brittany. But the name also occurs in Wales,
e.g. Llyn Llydaw in Snowdonia, and there are several cases of the use of the name in the older literature
which suggest that it was used for some region in Wales. Just as Devon [Dumnonia] and Cornwall gave
their names to Domnonée and Cornouaille in Brittany, so Llydaw [Brittany] seems to have had its
duplicate in Britain. John Rhys gave reasons for suggesting that a place named Llydaw was in the region
of Llangorse Lake in Brycheiniog (Celtic Folklore, pp.531-6). In the story of the hunting of the boar,
Trwyth, in the tale of ‘Culhwch and Olwen’, the men of Llydaw, gwyr Llydaw, are represented as
assembling in Ystrad Yw, a cwmwd on the south-east border of Brycheiniog (RM 140). In the Life of
St.Padarn (§22) it is said that Caradog Freichfras extended his boundaries of Britannia [Wales] so as to
include Letavia. This can be interpreted as extending his kingdom from Radnorshire into Brycheiniog.
See s.n. Caradog Freichfras. Again in the Life of St.Illtud (§1) it is said that his father was a man of
Letavia, and implies that Illtud was born there. Later we are told that he returned to Letavia to die, but
there is a tradition that he was buried in the parish of Defynnog in Brycheiniog. See s.n. Illtud, note to
§1 of the Life.
Many Welsh saints are said to be descended from Emyr Llydaw, and this has led to the
assumption that they migrated from Brittany. But there is no good reason for supposing that any of these
saints actually came from Brittany. All the evidence points to the contrary, and the movement was
almost wholly in the opposite direction. See Emyr Llydaw. It seems therefore that, in many cases when
Llydaw is mentioned in a context of the sixth century or earlier, Llydaw could mean a district
somewhere in the boundaries of Brycheiniog.
See also WCO 102, 111-2, 133, 135. 151; E.G.Bowen, The Settlements of the Celtic Saints in
Wales, 1954, pp.55, 94.
A curious passage in the Life of St.Oswald printed by John Capgrave says that ‘[Oswald] was
killed in the place called in the English tongue Maserfeld ... That place [Oswestry] moreover is adjacent
to the boundaries of Armorice Wallie - because anciently the greatest part of Wales was named
Armorica.’ (Nova Legenda Anglie, ed. C. Horstman, II.204)."
The answer to that mystery is the Leadon Vale, a river-name conforming to Celtic *Litano- and hence a perfect candidate for a British 'Llydaw.' I'd written many pieces on the Leadon and Illtud's possible origin there. Here are just a couple:
Alas, if Leadon Vale is Illtud's Llydaw, then the Irish connection to his son Arthur is lost.
Our second and biggest problem is, of course, the battles of the HISTORIA BRITTONUM and ANNALES CAMBRIAE:
Mouth of the River Glein
Dubglas River in Linnuis
Bassas River
Celidon Wood
City of the Legion
Tribruit Shore
Hills of Breguoin
Hill of Agned
Hill of Badon
Camlann
If Badon is Bath, as it seems to be (see https://mistshadows.blogspot.com/2026/09/badon-as-bath-final-proof.html?m=1), there's no problem with an Arthur based in the old Dobunni lands fighting there.
Without resorting to trying to identify them with English place-names, we can say that a couple more of the battles could be put in the South. The City of the Legion could be Caerleon - something that has long been suggested by various Arthurian scholars, professional and amateur alike.
The Tribruit, because this is a Welsh substitute for the Latin trajectus, a crossing, may well be the one recorded in Roman records at or near Bitton - which itself it quite close to Bath. Such a location also would put this battle practically right at the Dyrham site of the ASC.
But after that, things get hopelessly mirky. It is interesting that in the ASC that after the battle of Dyrham, three cities are captured - Bath, Cirencester and Gloucester. Three cities in the ASC, and three hills in the HB. But, perhaps more interesting is that there are three hillforts at Bath: Little Solsbury, Bathampton and Little Down. Might there be some correspondence between one group of three and the other?
The Celidon Wood is quite impossible. Try as we might there is really nothing we can do with it unless we try to make it conform to some similar looking or sounding English name. Any identification reached by that method will not satisfy anyone other than people who lack all knowledge of place-name development and the various languages involved. We could have fun with it: there is a Chilton hard by Cadbury Castle in Devon. Yet there is really no way to escape the fact that the Celidon Wood is the Celidon Wood. If it's something else, we can't possibly prove what that is.
Bassas forces us in one of two directions: we look for an English Bassa stream, like that of Bassingbourn in Cambridgeshire, or we accept an impossible to locate 'shallow' (W. bas) stream or shallow of a stream.
The Glein, followed immediately by a Dubglas in Linnuis, does seem to suggest that whoever compiled the list may have been thinking of the Lincolnshire Glen (in the region of the Roman period Lindum). Alas, there is no Dubglas in Lindsey and, so far as we know, never has been. There is a Blackwater at Witham in Essex, and a Witham River in Lincolnshire. The earliest forms of the two Witham names are not identical (see Ekwall, Watts, etc.), but I suppose it's possible they were confused and so the Essex Blackwater was placed accidentally in Lindsey. But, again, this is relying on English place-names. And there are other Glens (although not always deriving from W. glein) and Douglas (some being Gaelic) rivers around. There was a Lindinis Roman town at Ilchester in Somerset.
Camlann, because of the Gallic St. Medard of Noviomagus's intrusion into the AC entry, looks to be the ANGLO-SAXON CHRONICLE'S Cymenesora (a site near the British Noviomagus/Chichester). However, we have the odd presence of an early Llanelltyd church near the Afon Gamlan in NW Wales. The Afon Gamlan is the Camlann of later Welsh tradition. It is possible the Afon Gamlan is a relocation of Cymenesora and the church of Illtud was put there in the mistaken belief Arthur really had perished in Merionethshire.
Rather than trying to identify the battles which seem to belong firmly in the North with southern sites, it might be better to accept them as an attempt by the author of the HB to further glorify Arthur by placing him all over Britain.
The real Dark Age war-leader may have been based in Dobunni lands. How the name Artorius came to be transmitted there would remain unknown.
I realize none of that will sit very well with my readers. It does feel, well, unfulfilling. But if we are going to keep an Arthur son of Illtud, this is the best I can do, I'm afraid. We end up with an Arthur disassociated from several of his battles and with no discernible Irish ties.
