The Astronomy of Math vab Mathonwy (part 1)

The Astronomy of Math vab Mathonwy (part 1)












Bear-born son of the Little Bear, King of the North

'Math son of Mathonwy was lord over Gwynedd'.

These, the first words of the Fourth Branch of the Mabinogi, are the first major indication that the characters in this medieval Welsh tale are being sourced from graphic images of the classical constellation figures which adorned the celestial planispheres or star charts of the Middle-ages. I believe that these introductory words are a reference to two specific constellations and that they were intended to give readers or an audience their bearings. The word bearings is an old navigational term which stems from the fact that the two northern celestial bear constellations Ursa Major and Ursa Minor are circumpolar, the Greater Bear points to the Pole Star and the Lesser Bear contains the Pole Star and neither constellation sets below the horizon. Hence 'North' on old maps is written Septentriones referring to the seven stars of these respective Bears, also recall 'Arctic' meaning 'of the Bears'. To know this is 'to know your bearings'. I think that the author of The Fourth Branch had in mind the most northerly constellation figures of Cepheus the King and Ursa Minor the Little Bear when he first drew the figures of Math vab Mathonwy and Goewin his footholder.1  How have I arrived at this conclusion? To answer that question we need first to establish the known facts concerning Math vab Mathonwy and his footholder Goewin.

Math vab Mathonwy
Professor W. J. Gruffydd's analysis of the name Math vab Mathonwy is as follows: He equates Irish Mathgen with Math. 'Math belongs to a well known order of names...deriving from animals; Gaulish Artogenos, "son of bear" and Matugenos "Son of the Bear" are examples...The Irish Mathgen [bear-born], if borrowed into Welsh, would be written in Old Welsh Mathgen, and in Medieval Welsh Mathyen or Mathien. It will by this time be clear that the name Math is a corruption of Mathien.'...'Speculation as to his father's (or mother's ) name, Mathonwy, must be largely a matter of conjecture. It has been suggested by Professor Zimmer that it is an adaptation of the Irish name Mathgamnai, anglicised Mahoney. In the Irish Bible, as de Jubainville points out, the Hebrew do^b, "bear," is translated mathghamhuin, which literally means a "bear cub." Whether there be any connection between these words and Mathonwy it is difficult to say‘. However, he concluded (and other major scholars, such as Rachel Bromwich have concurred): " We may then translate Math(ien) vab Mathonwy as "Bear(kin) son of Bearling…" Bearling meaning 'bear cub' or 'little bear'. On the face of it this presents us with a very strange idea indeed; it is easy to imagine a powerful warrior king in an heroic age society being named as "Son of the Bear", but what would it have meant to be named “Son of the Bear Cub“ or “Son of the Little Bear”? As a patronymic (or matronymic), it appears, at least on the surface, more demeaning than heroic.

Goewin
A peculiar characteristic of Math is that he must have his feet in the croth, literally ‘womb’ but usually translated ‘fold’, of a virgin’s lap in order that he may live. The name of this virginal footholder is Goewin which translates as 'the Brave One'. This odd situation represents another departure from the norm because although medieval Welsh law provided space for the king’s foot holder, the position appears to have been an exclusively male one. In the normal run of affairs the presence of the foot holder elevated the king above ordinary men but Math's situation makes him beholden to the footholder, his life depends upon the presence of his virginal female footholder. Therefore, rather than being elevated by his footholder Math's status is, it would seem, diminished; his power to act in the world is thus severely curtailed and in consequence Math is unable to do a circuit of the country (gylch y wlat). The picture emerging here is, therefore, a static one, the Son of the Little Bear and his 'brave' footholder are effectively immobile, held symbolically at the centre of the land. This status quo can only be altered, we are told, in the event of a war.

Hutlath
Although Math is not the principal character in the Fourth Branch, he is literally, as well as figuratively, a central character. Events occur around him and because of him, sometimes through the agency of his hutlath or magic-wand which he will use to transform his nephews into wild beasts and whom he forces to mate and have human offspring, to test the virginity of his niece and to create a flower-faced woman not 'from the race that is on the earth'. As regards Maths wand or hutlath, Gruffydd alludes to the poem Daronwy from The Book of Taliesin in which it is stated that:
"Few there are who know where
the magic wand of Mathonwy grows in the wood"

Whatever the confusion here between Math and Mathonwy, it is certain that "Mathonwy like Math is distinguished as the possessor of a magic wand", and that knowledge of the whereabouts of this wand is, it is intimated, secret or privileged information.

Draco
Though it is not mentioned in the tale, the symbol for the Gwynedd royal house has, since post Roman times, been that of a dragon and this would have been common knowledge to both the author of Math vab Mathonwy and his audience. It is widely considered that the red dragon which adorns the national flag of Wales may have had its origins in the so called Draco standards of the Romans. Following their withdrawal this Draco standard was apparantly adopted by the Welsh kings of Aberffraw symbolising the continuation of Roman style administration. As early as the sixth century Gildas, in De Excidio et Conquestu Britanniae, names the Gwynedd king Maelgun Maglocunos Draco. Around the seventh century, it became known as the Red Dragon of Cadwaladr, (king of Gwynedd from 655 to 682), and it is recorded in the Historia Brittonum (Nennius) as being the symbol of Gwynedd at least as early as the 8th century.

Caer Dathyl
The whereabouts of Caer Dathyl, Math's principal abode, has long been a matter of speculation. It has variously been associated with Tre'r Ceiri, Pen Y Gaer, Caer Engan, Caernarfon, Pen Dinas, Craig Y Dinas and Y Foel or perhaps it no longer exists because it has fallen into the sea. Gruffydd derives Dathyl from the more correct form Dathal or Tathal, a Welsh adaption of the Irish Tuathal. I wondered what this word Tuathal meant and what it's origin was. I do not having any formal education in etymology and so I gleaned most of the following from a web site for scholars and students of Old Irish called Old Irish-L Archives.
There are two words to consider:
1. Tuath translates as people, tribe, nation. As in the Tuatha de Danaan - the people of (the goddess) Danu, (cognate with Welsh 'Don' the sister of Math).
2. Tuath- (used in compounds) translates as northern, left, on the left; consequently perverse, wicked, evil, sinister.
Whether the two words are related seems to be an open question. Macbain gives Rhys' suggestion that Scots Gaelic -tuath- - 'north' may come from do-huth < to-su - 'turning to' the root being -su- 'turn'. Interestingly, in view of Math's ability to hear even the quietest whisper, Pokorny suggests that tuath comes from proto Indo- European teu - 'to listen, to observe'. He also noticed middle Welsh tut - 'magician' cognate with middle Irish tuathhaid -'magician'. The history of this word then carries these meanings: 'the people', 'of the north', 'turning (to the left?)', 'listening', 'magician'. To what extent the author and his audience where aware of these connotations is open to speculation, but it must be remembered that most, if not all monks were at least bilingual and some were trilingual. In Wales, it would not have been unusual for a monk to be fluent in Welsh, Latin and Irish or even in English and French. Moreover, there was in fact a great deal of interest in etymology, (however inexact) as is evidenced by the popularity of Isadore of Seville's etymological encyclopaedia.


Royal Family
Finally, mention should be made here, concerning three of Math's close relatives all of whom have traditional associations in Wales with the Ptolemaic constellations. Cassiepeia (the wife of Cepheus) is known in Wales as Llys Don, Don is the sister of Math. Corona Borealis is known in Wales as Caer Aranrhod, Aranrhod is the neice of Math. The Milky Way is known in Wales as Caer Gwydion, Gwydion is the nephew of Math. (I will show later that the author intended that Aranrhod represented Andromeda, the daughter of Cepheus).

Grouping all of these characteristics together it is clear that this is an exact description of the constellation figure of Cepheus (son of Cepheus or sometimes of Belos ). A comparison may be tabulated thus:

Math is the king of the 29 cantrefs of the North. Cepheus is the King of the 27 constellations of the Northern Hemisphere.

Math vab Mathonwy means 'Bear-born son of Little Bear'. Cepheus appears to be the son of the Little Bear.

It is true of both Math and Cepheus that their "feet are in the fold of a virgin's womb".

The name of the footholder is Goewin – 'the Brave One'. The (brave) Little Bear is known as the 'king's footstool'.

Math cannot make a circuit of the land. Cepheus cannot make a circuit of the sky.

Math carries a powerful magic wand. Cepheus carries a royal sceptre.

The emblem of Gwynedd is the Red Dragon. Cepheus sits on the Dragon throne, Draco.

Math's sister is Don, in Welsh tradition Cassiepeia. Cassiepeia in Greek tradition is the wife of Cepheus.

Math's niece is Aranrhod, in Wales Corona Borealis Corona Borealis is a Northern constellation

Math has in his family tree Beli Mawr and Don. Cepheus son of Cepheus has in his family tree Belos and Danae.

I am led to several conclusions:

1.The name Math vab Mathonwy, 'Bear-kin son of Bearling', can now be explained as a descriptive term for the graphic figure of the constellation Cepheus with respect to the figure of the constellation Ursa Minor, i.e. Ursa Minor, (the bearling) appears to have given birth to Cepheus, the King of the North. What seemed at first to be a puzzlingly demeaning name can now be seen as a good technical description of the appearance of the Northern-most of the circumpolar constellations. Gruffydds assertion, (and both Rachel Bromwich and Marged Haycock concurred) that Math vab Mathonwy belongs to that class of nonsense names such as are found in Culhwch and Olwen (Suck son of Sucker, Ear son of Listener’, ‘Aim son of Aimer’ etc.) is therefore a red herring. Indeed this whole notion of male animals giving birth to humans is a central and deeply embedded theme of this tale, and it may be that it was intended to be an amusing irony that it was Math (Bear-born) who inflicted the bestial punishments upon Gilvaethwy and Gwydion which resulted in the three sons of Gilvaethwy, Bleiddwn - Wolf-born, Hyddwn - Stag-born and Hychtwn - Swine-born.

2.The peculiarity of Math that he must have his feet in the 'fold of a virgin's womb' can thus be recognised in this configuration. Geowin - the brave one is therefore to be identified with the constellation figure of Ursa Minor which has been called 'the king's footstool', for obvious reasons.

3. Furthermore, we find here not just the source for these two characters but also the inspiration for the narrative foil which will drive the events of the first episodes of Math vab Mathonwy.



Confronted with this image of the wand waving king of the north who appears to be emerging from the womb, of Ursa Minor and apparently seated next to a dragon, I do not doubt that a medieval audience to this tale would have had any difficulty in identifying the constellation Cepheus with Math vab Mathonwy, (Bear-born Son of the Little Bear), lord of Gwynedd (the king of the North) whose feet are resting on the croth of his virginal footholder.. Note that close by sits his sister Don (Cassiepeia).

Notes
1.Later in the tale, I will argue, when Goewin is pregnant and Math makes her his wife, she can be seen as representing Ursa Major the Greater Bear, in the same way that Zeus made Callisto the queen of Heaven.

Caer Gwydion

Caer Gwydion 

"His residence was among the stars and called Caer Gwydion".i


Introduction

There is an intriguing note to Lady Charlotte Guest's 1846 translation of Math the son of Mathonwy regarding the character of Gwydion, arguably the lead character in the Fourth Branch. This note was the starting point to this inquiry. She wrote as follows:

Gwydion ... He was...a great astronomer, and as such was classed with Gwynn ab Nudd, and Idris. The Milky Way is after him termed Caer Gwydion: similar honours indeed appear to have been paid to the whole family of Don. Himself (sic), gave his name to the constellation of Cassiopeia, in Welsh, Llys Don, the Court of Don; and Caer Arianrod, Corona Borealis, is so called after his daughter Arianrod, one of the heroines of the present Tale.ii

What were Lady Guest's sources, where does this material originate, most importantly, did the author of Math have these celestial associations in mind, did he equate the Milky Way with Gwydion, Cassiopeia with Don, Corona Borealis with Aranrhod? Is it legitimate to ask whether he may have associated other characters in the Fourth Branch with other constellations? Math and Geowin, Pryderi, Llew and Gronw Pebr; did these characters belong to an astronomical scheme too? 

Without doubt, Lady Guest's initial reference is to the infamous 'third series' of Triads penned by Iolo Morgannwg and published in Y Myvyrian Archaiology in 1807:

89. The Three Renowned Astronomers of the Isle of Britain:
Idris the Giant;
Gwydion son of Dôn;
And Gwyn son of Nudd.
Such was their knowledge of the stars, their natures and qualities, that they could prognosticate whatever was wished to be known until the day of doom.iii

Through her friendship with Taliesin Williams, Iolo's son, she also would have had access to the list of 37 constellations which gives, according to Iolo, the original Welsh names for the constellations, later to be contained within Volume I of Y Barddas also by Iolo Morgannwg, edited by J. Williams Ab Ithel and published in 1862:

Caer Gwydion, The Circle of Gwydion; 

The son of Don; one of "the three sublime astronomers of the Isle of Britain." 

Tr. 89, third Series. The Galaxy.iv

However spurious the context of Triad 89 it is certain that these celestial associations had been handed down from an earlier period. Fifty years before the publication of the Iolo Manuscripts Lewis Morris (1701–1765) recorded in his Celtic Remains (completed in 1757, though it remained unpublished until 1878) the following:

Gwydion or Gwdion, Son of Don, Lord or Prince of Arvon. This Gwdion was a great philosopher and astronomer, and from the Via Lactea, or Milky Way, or Galaxy, in the heavens is called Caer Gwdion. His great learning made the vulgar call him a conjuror and necromancer; and there was a story feigned that when he travelled through the heavens in search of ...'s [sic] wife that eloped, he left this tract of stars behind him.v

One hundred and fifty years before Morris's entry, John Jones of Gelli Lyvdy, 'noted in a MS. written by him before 1619':

Gwraig Huan ap Gwydion, a vu un o ladd ei gwr, ag a ddyfod ei fyned
ef i hely oddi gartref, ai dad ef Gwdion brenhin Gwynedd y gerddis bob tir yw amofyn, ac or diwedd y gwnaeth ef Gaergwdion (sef: via lactua) sy yn yr awyr yw geissio: ag yn y nef y cafas ei chwedyl , lle yr oedd ei enaid: am hynny y troes y wraig iefanc yn ederyn, a ffo rhag ei thad yn y gyfraith, ag a elwir er hynny hyd heddiw Twyll huan.vi

       The wife of Huanvii ap Gwydion was one in a plot to kill her husband, and said that he had gone away hunting, and his father Gwydion, King of Gwynedd, travelled every country to seek him and at last he made Caergwydion, (that is, via lactua [sic]), which is in the sky, to find him: and in heaven, he had news of him, where his soul was. Therefore he changed the young woman into a bird, and she fled from her father-in-law, and she is called from that day to this Huan's Deceiving (Twyll Huan).viii

Of these two related episodes that John Jones is alluding to here the first is, very obviously, where Blodeuedd and Gronw Pebyr had previously colluded in the attempted murder of Lleu Llaw Gyffes (Huan), but on receiving the wound from Gronw's magically prepared spear, Lleu had flown away in the form of an eagle and Gwydion had set out in search for him. It is important to emphasise at this point that W.J. Gruffydd, in his seminal study of the Fourth Branch, uses this John Jones 'variant' on two occasions to 'prove' his point that in an earlier version of Math, (i.e. than the White Book redaction) Gwydion was the father, (and not merely the uncle) by incest with Arianrhod, of Lleu.ix Gryffudd however makes no comment at all on the astronomical nature of the rest of the passage though presumably he accepted this aspect as an integral part of this ‘earlier version‘. This is how Jones and Jones translated the relevant passage from The White Book of Rhydderch:

         Then the tidings reached Math son of Mathonwy. Heaviness and grief Math felt within him, and Gwydion more than he by far. 'Lord,' said Gwydion, 'I shall never rest till I have tidings of my nephew.' 'Aye,' said Math, may God be thy strength.' And then he set out and began to go his way, and Gwynedd he traversed, and the length and breadth of Powys. When he had traversed every part, he came to Arfon, and came to the House of a villein in Maenawr Bennardd. He alighted at the house and stayed there that night.x
        
Has John Jones's apparently extraneous material been omitted or even 'censored' from the extant tale, or contrary to Gryffudd's opinion, is it a later embellishment unrelated to the intentions of the author of Math? There are several points of interest here. First, the tradition, which John Jones recorded in the early seventeenth century, supplies an alibi or 'cover story' for Blodeuedd and Gronw's treacherous act. In order to explain Lleu's disappearance Blodeuedd must have told Gwydion that Lleu 'had gone away hunting' with the implication that he had not returned. This detail, which might be thought of as necessary to the flow of the narrative, is strangely lacking in Math, we are only told that, 'Then the tidings reached Math son of Mathonwy'. We are not told what tidings, neither is there any suggestion that either Math or Gwydion knew of the true fate of Lleu. Furthermore, the actions of Gwydion were not, at this juncture in the tale, directed in the least against Blodeuedd and Gronw. Even when Gwydion does finally find Lleu in the topmost branches of the 'world tree', it only occurs to him that the eagle is Lleu, but he doesn't know that it is. It may be inferred from this therefore, because we cannot otherwise explain the actions of Gwydion, that the 'cover story' given by Blodeuedd, (according to Jones) i.e. Lleu 'had gone away hunting', was at one time included in 'Math' and was, for whatever reason, omitted from the extant redactions contained in the Red and White Books.

It is possible to detect further striking evidence that this seemingly late and isolated story fragment once formed an integral part of the Mabinogi of Math. Consider the uncanny similarity of language of the Fourth Branch compared with the 'Jones fragment', Math has it that Gwydion 'traversed every part', and Jones relates that he 'travelled every country'. In addition, the Mabinogi has Gwydion say: 'I shall never rest till I have tidings of my nephew.' And the Jones' tradition supplies: 'and in heaven, he had news of him, where his soul was'. Is this where and how Gwydion learnt that a sow would lead him to Lleu? In the extant Mabinogi, Gwydion's arrival at the pig farm reads like an amazing stroke of luck. Once more the ‘Jones fragment’ supplies a rational narrative explanation for Gwydion's, otherwise unexplained, good fortune.

It would seem from this that what we have here is not an excerpt from a variant tradition, or a later imaginative re-rendering of Math but a fragment of an earlier literary version from which the extant text must have been derived. Did John Jones have access to this, now lost, version? Perhaps. With this tentative conclusion in mind, it is now worth placing side by side the following passage containing the astronomical allusions, from the tradition preserved by John Jones with the relevant passage from Math, as translated by Jones and Jones:

[Gwydion] travelled every country to seek him and at last he made Caergwydion, (that is, via lactea), which is in the sky, to find him: and in heaven, he had news of him, where his soul was. (Jones)

When he [Gwydion] had traversed every part, he came to Arfon, and came to the House of a villein in Maenawr Bennardd. He alighted at the house and stayed there that night. (Jones & Jones)

I want to focus now on the word 'alighted'. In the White Book of Rhydderch, the Welsh word used is diskynnu. Ford gives the following meaning: diskynnu - 'come upon; alight'.xi The Red Book of Hergest has dysgynnu the same as modern Welsh - dysgynnu - which is defined in Y Geiriadur Mawr,xii as 'to descend'. The Oxford Paperback Dictionaryxiii defines 'alight' thus: 'to descend and settle' and gives the following example of usage: the bird alighted on a branch. It would be amiss not to acknowledge that this word diskynnu/dysgynnu also carries the meaning 'to dismount', as from a horse, as does the English word 'alight' and this is how it has been interpreted by several translators including Gruffydd, Gantz, Bollard and Davies. Even those translators who have elected to use the word 'alighted', who include Lady Guest, Ford and Parker, most likely understood this word in the context of 'dismounting a horse'. But why should this be so? Jones and Jones certainly understood 'alighted' in the context of a bird coming to rest, for they use it in this sense, shortly after the instance under consideration, to describe Lleu's descent in eagle form:

And he let himself down till he was on the lowest branch of the tree...And he alighted on Gwydion's knee.xiv

Nowhere, in the relevant part of the text of Math, is there any mention of a horse from which Gwydion could dismount. The fact is that the only other version of this episode that we possess is the one preserved by John Jones which insists that Gwydion searched for Lleu in the Milky Way, 'which is in the sky'. The presence in Math of the word 'alighted', (diskynnu/dysgynnu)xv with it’s connotation of a bird coming to land, is therefore a matter of great interest because it too argues for the inclusion of the John Jones version of events in an earlier redaction. Leaving aside the question of Lleu's parentage, a more complete and harmonious version may now be reconstructed as follows:

Blodeuedd, the wife of Llew Llaw Gyffes, said that he had gone away hunting, and had not returned. Then these tidings reached Math son of Mathonwy. Heaviness and grief Math felt within him, and Gwydion more than he by far. 'Lord,' said Gwydion, 'I shall never rest till I have tidings of my nephew.' 'Aye,' said Math, may God be thy strength.' And then he set out and began to go his way, and Gwynedd he traversed, and the length and breadth of Powys. When he had traversed every part, and travelled every country to seek him he made Caergwydion, which is in the sky, to find him: and in heaven, he had news of him, where his soul was. At last he came to Arfon, and came to the House of a villein in Maenawr Bennardd. He alighted at the house and stayed there that night.

A further episode is mentioned, almost in the same breath, by John Jones, which we can recognise from the extant version of Math. This time the reference is to Gwydion's search for and transformation of Blodeuedd. Significantly, as has been mentioned, Lewis Morris, in the eighteenth century, related a version that has this action taking place in, or more specifically, resulting in the formation of, the Milky Way. Unfortunately, he appears not to have remembered the names of the charactersxvi and there is more than a suggestion here that he has heard, rather than read the story, although he attributes it to David Johns (fl. 1573-87)xvii:

...and there was a story feigned that when he (Gwydion) travelled through the heavens in search of ...'s [sic] wife that eloped, he left this tract of stars behind him.

Lady Charlotte Guest‘s translation of this episode, (from the Red Book of Hergest) is as follows :

Then they called together the whole of Gwynedd, and set forth to Ardudwy. And Gwydion went on before and proceeded to Mur y Castell. And when Blodeuwedd heard that he was coming, she took her maidens with her, and fled to the mountain. And they passed through the river Cynvael, and went towards a court that there was upon the mountain, and through fear they could not proceed except with their faces looking backwards, so that unawares they fell into the lake. And they were all drowned except Blodeuwedd herself, and her Gwydion overtook. And he said unto her, “I will not slay thee, but I will do unto thee worse than that. For I will turn thee into a bird; and because of the shame thou hast done unto Llew Llaw Gyffes, thou shalt never show thy face in the light of day henceforth; and that through fear of all the other birds. For it shall be their nature to attack thee, and to chase thee from wheresoever they may find thee... and that thou shalt not lose thy name, but that thou be forever called Blodeuwedd... And the owl (tylluan)xviii is still called Blodeuweddxix.

Unlike Morris's version, John Jones's account omits to tell whether these events should be seen as taking place in the Milky Way, but they do follow on immediately after Gwydion's celestial adventure in search of Huan (Lleu) and like this episode, despite the obvious name changes and the back to front structure, the language of Gwydion’s transformation of Twyll Huan again has strong echoes of the White Book redaction:

The wife of Huan ap Gwydion was one in a plot to kill her husband.
Therefore he (Gwydion) changed the young woman into a bird...
and she fled from her father-in-law...
and she is called from that day to this Twyll Huan.

When the corresponding text from Math is combined with the narrative structure of the Jones fragment, a very close relationship is revealed:

...because of the shame thou hast done unto Llew Llaw Gyffes...
he (Gwydion) said unto her I will turn thee into a bird...
she... fled to the mountain and her Gwydion overtook...
And the owl is still called Blodeuwedd.

Note the change of name from Blodeuedd (Flowers) to Blodeuwedd, (Flowerface). A similar onomastic twist is also implied in Jones's version: 'she is called from that day to this Twyll Huan' (Huan's Deceiving), the Welsh word for owl is Tylluan. There is a curious persistence here, in both cases a change in the spelling of the name of the wife results in a homonym signifying 'owl' and one is given the strong impression, once again, that Jones's source is a literary one. Moreover, one that is demonstrably closely related to the extant tale of Math in the White and Red Books.

'Thus, after the manner of the Greeks, the Britons formerly treated their stories and tales in order to keep them in memory'. In this way does John Jones conclude his account of Gwydion's search for Huan (Lleu) in the Milky Way and of the punishment of Twyll Huan (Blodeuwedd), though it is not made clear just where this mnemonic quality lies, or how it relates to the tales of the Greeks. How curious an echo this is of Jones’ contemporary and friend Dr John Davies's scrawled Latin note at the end of the Mabinogi of Math in the manuscript White Book of Rhydderch, 'This author strives, with his creations, to outdo the Chimera, or whatever monstrous creature all of Greece has to offer'.xx

Daniel Huws has described John Jones of Gellilyfdy as 'the most heroic of all transcribers of Welsh literature'xxi. He was certainly no Iolo Morgannwg and has never been accused of 'invention'. However, the fact that Jones may have had access to the White Book at about the time (1619) that he made this notexxii, might lead one to suspect that his source was in fact the White Book itself and that the extra, astronomical details were added in by him from some other, perhaps more recent, source. I do not believe this for a moment, John Jones was an honest man. J. Gwenogvryn Evans described his character thus:

In services to Wales and its literature John Jones takes precedence of all his namesakes... The Dictionary of Eminent Welshmen...informs us "that he was an attorney in the court of the Marches of Wales, and that he early withdrew himself because he had too much honesty to pursue it." ...his interest in the Welsh language, and its literature dominated his whole life. For over forty-years we find him steadily at work making really beautiful copies of every old manuscript he could borrow and were it not for this supreme, though indiscriminate devotion of his pen to things Welsh, we should have lost altogether certain texts, which no longer exist except in his transcripts.xxiii

In any case, we can trace Gwydion's specific association with the Milky Way to an even earlier period, because at least seventy years before John Jones made his careful copy of a now lost manuscript, another great renaissance Welshman called William Salesbury, recorded in his groundbreaking Dictionary in Englyshe and Welshe in 1547 that 'Caer Gwydion' was the Welsh name for the Milky Way. Salesbury's stated aim, in his preamble address to Henry VIIIth, was to educate the Welsh as to the pronunciation of the English language and this was in line with Henry's policy, (despite his own Welsh ancestry) of uniting England and Wales under the aegis of English cultural hegemony. There can be no conceivable reason, therefore, why Salesbury might have invented this equivalence and though no history or etymology is given in his dictionary, it might be guessed, given the conservatism of the Welsh language, that this usage of 'Caer Gwydion' for the Milky Way was not a recent innovation. We have now travelled backwards in time exactly three hundred years since the publication of Lady Guest's Mabinogion, where this enquiry began, and it transpires that, by the middle of the sixteenth century, Caer Gwydion was part of the common parlance of the ordinary Welsh speaking men and women of Wales. That this was also the case in the two previous centuries is proved by the presence, as Mark Williams has noted, of 'Caer Gwydion' in relation to the Milky Way in the poetry of Lewis Glyn Cothi, writing in the late fifteenth century, and of Gruffudd Grug writing in the late fourteenth century. Both referred to the Milky Way using the term 'Caer Gwydion', and both poets were contemporaries of the scribes of the extant redactions of Math vab Mathonwy. Why did these poets choose to refer to this celestial version of Math whilst the scribes of the Red and White books apparently chose to edit out all overt reference it? Before attempting to answer this question it is worth examining the extant version(s) of The Fourth Branch to see if there are any further traces of evidence of this astronomical 'variant'.

I propose that we can point to three further instances within The Fourth Branch, which allude to, if only just below the narrative surface, an astronomical explanation for Gwydion, These instances also focus on certain avian attributes and, if this is accepted, a constellational identity for Gwydion, within the Milky Way, appears to present itself, the constellation in question is Cygnus the Swan.

The first instance is when Gwydion is disguised as the Pencerdd or 'the chief poet' at the court of Pryderi. In order to be convincing in the part he would be required to wear a tugen, as was the legal privilege of the pencerdd, this was a mantle made from the feathered pelts of various water birds but very often described as being simply a mantle of swan feathers.xxiv To complete the disguise he must carry a harp, not the modern Welsh harp but the 'crwth' of medieval Wales, the older Welsh version of the lyre, in other words he is disguised as a swan with a lyre. Second, in the conversation between Pryderi and Gwydion (wearing his swan feather mantle, idly plucking his lyre) following the evenings entertainment at Rhuddlan Teifi, Gwydion enquires of Pryderi, 'can anyone deliver my request to you better than I myself?' Pryderi's apparently throwaway reply is illuminating and may well have elicited knowing laughter from a learned audience, 'No indeed,' said Pryderi. 'Yours is a very good tongue.'xxv Is this an aside to an audience, a pun? Whether swans tongues were a delicacy served at the tables of British noblemen I could not say, certainly entire swans were served at medieval banquets. But perhaps the more apt pun is directed towards the ancient and widespread notion that, only the tongue of a swan was able to separate milk from water. This idea was based on the swans' reputation as the purest of birds, only the tongue of a swan was good enough to separate fact from fiction. Third, the final visit that Gwydion and Lleu make to Caer Aranrhod again emphasises their changing appearance in order to be disguised as poets, with the implicit invitation to the audience/readership to visualise this transformation once more, which in all likely-hood involved Gwydion carrying a lyre and donning a swan feathered pelt. 

Another reason for suspecting a connection between Gwydion and Cygnus and Lyra concerns Gwydion's portrayal in the Cad Goddeu as a sort of avatar of Orpheus, who, according to Ovid's Metamorphoses, on his return from the Underworld animates the trees by plucking the strings of his lyre, exactly as Gwydion does in The Battle of the Trees. Orpheus, according to Plato was transformed upon his death into the constellation Cygnus and placed next to Lyra.

Finally, following his adventure in the Milky Way, (according to the John Jones frament) Gwydion sings three englynion to Lleu/Eagle, who is located at the top of what most commentators agree represents the World Tree or the Axis Mundi. The second englyn contains an interesting number:

... With that the eagle let himself down till he was in the middle of the tree. Then Gwydion sang another englyn:

Grows an oak between two lakes.
Nor rain wets it, nor heat melts;
Nine score hardships hath he suffered
In its top, Lleu Llaw Gyffes.

It is curious that the eagle 'was in the middle of the tree'. but that Lleu Llaw Gyffes was 'in its top', this apparent discrepancy disappears if it is accepted that Llew and the eagle were intended, in the mind of the author, to represent the constellations of Perseus and Aquila respectively. To appreciate how neat an explanation this is, a very useful tool is the Philips Planisphere for 51.5 degrees North, this allows you to track the movements of the constellations over time as they appear to an observer in Wales. This enables you to watch Perseus/Llew set in the North while Aquila/Eagle rises in the East and then travels 180 degrees (nine score hardships) across the sky to set in the West, with Perseus/Llew now in the topmost branches of the (world) tree, i.e. at Zenith. I will discuss this particular episode in more detail later, for now it is sufficient to illustrate how the numbers in Math lend convincing support to the idea that there is an embedded level in the tale which can only be understood in terms of Astronomy.


Aquila the Eagle has traversed 180 degrees or 'nine score hardships' to set in the west, Cygnus or Gwydion has also traversed 'every part' to find Lleu Llaw Gyffes or Perseus, who is is at the very top of the sky. (The chart is Schaubach's northern hemisphere).

In all of this, it is difficult not to see the constellations of Cygnus the Swan, which dominates the Milky Way of the northern celestial hemisphere, and of the adjacent Lyra the Harp. To the medieval Celtic mindset the image presented by Cygnus and Lyra would have been immediately recognisable as a 'pencerdd', particularly so, if the narrator/performer of this tale happened to be a similarly accoutred chief poet. Note also that Lyra was often depicted as The Desert Falcon which like the owl is a nocturnal predator, and in the case of Lleu Llaw Gyffes note that Aquila the Eagle is also a constellation of the Milky Way. When this is combined with what can be gleaned from the evidence of Lewis Morris and John Jones, it would not be unreasonable to suppose that the author of Math fab Mathonwy, in telling the story of Gwydion, Blodeuwedd and Lleu, had in mind the group of constellations anciently known as the Stymphalian Birds, Cygnus, Lyra and Aquila. In modern times, many people are familiar with this group from their brightest or alpha stars, respectively Deneb, Vega and Altair for which we must thank another legendary Astronomer Patrick Moore for coining the phrase 'The Summer Triangle'.

viii Gruffydd's translation. Compare with this translation from www.maryjones.:
'The wife of Huan ap Dôn was a party to the killing of her husband, and she said that he had gone to hunt away from home. And his father, Gwydion, the King of Gwynedd, traversed all countries in search of him, and at last made Caer Gwydion, that is the via lactea, which is in the sky, to seek him. And he found him in heaven, where was his soul. And for that he turned the young wife into a bird and she fled form her father-in-law, and is called to this day Twyll Huan. Thus, after the manner of the Greeks, the Britons formerly treated their stories and tales in order to keep them in memory'.

xv There are at least two other instances in the Mabinogi where 'alight' has been used to describe a
bird descending and settling - for example, Lady Guest and W.J.Gruffydd translate the crucial
incident in the naming of Llew Llaw Gyffes in almost identical fashion "And thereupon, lo, a wren
alighting/alighted on board the ship". Ac ar hynny llyma y dryw yn seuyll ar vwrd y llog. (but Ford
gives: seuyll - 'stand'. modern Welsh = sefyll - 'to stand'.) And in 'Branwen Uerch Llyr' in the
episode in which Branwen sends a starling with the message tied around its leg, to Bran the
Blessed, the identical sense is given... "It alighted on his shoulders and ruffled its feathers until the
letter could be seen, and it was realised that the bird was reared among dwellings", 'A diskynnu ar e
yscwyd, a garwhau y phluf, yny arganuuwyt y llythyr, ac adnabot meithryn yr ederyn yg kyuanned'.
(Branwen Uerch Llyr. Derick S. Thomson. The Dublin Institute For Advanced Studies).
There are two instances in Cilhwch and Olwen; Both Menw son of Teirgwaedd and Gwyrhyr
Interpreter of Tongues changed themselves into bird form and both alighted above the lair of
Twrch Trwyth. In all of these cases the author was thinking of Corvus the Crow - Welsh Bran.

The following quote from 'The Siege of Druim Damhghaire' concerning the druid Mogruith is
explicit in it's description of the ability of druids to fly to 'the heavens', which here must mean the
starry firmament Mogruiths skin of the bull was brought to him and also his enchennach (bird-
dress) with its flying-wings. Then he rose up, in company with the fire of the earth and flew into
the air and the heavens.

xxv It is possible that this whole vignette was intended to be amusing and self referential; potentially, we
may picture an actual scene, where during a performance of Math, a swan feathered, lyre carrying
chief poet may have told this story, about a swan feathered, lyre carrying chief poet who is telling
stories to a Welsh chieftain, to a Welsh chieftain!
