INTRODUCTION
The Heuneburg, beside the upper Danube in Baden-Württemberg (Germany), is increasingly and justly celebrated as one of the most important proto-urban Iron Age sites of the Late Hallstatt period. Unsurprisingly, since it is not very far from the river’s source, it has been claimed to be the Celtic polis of Pyrene at the source of Danube mentioned by Herodotus (c 485–424 bc).Footnote 1 In the twentieth century this identification completely supplanted older ones, such as Pfohren near Donaueschingen, first proposed by Beatus Rhenanus in 1531,Footnote 2 and a mons Piri (near Heidelberg?), discussed by Theodor Bergk in 1887.Footnote 3 The Heuneburg is now advertised to the general public as a ‘possible’ or ‘probable’ candidate to be Herodotus’s Pyrene or, more definitely, as ‘Heuneburg – Celtic City of Pyrene’, the ‘oldest city north of the Alps’ when ‘ancient Rome was still a small village on the Tiber’.Footnote 4 Professional archaeologists, however, often emphasise that Heuneburg being Pyrene ‘cannot be proved’ and ‘remains only a hypothesis’,Footnote 5 and many operate without mentioning the equationFootnote 6 or reject it, rightly in my opinion; for example, John Collis:
Despite claims that perhaps the Heuneburg was Pyrene, the greater likelihood is that Herodotus, like Aristotle, was confused about where the Danube rose.Footnote 7
Whether or not Herodotus’s Pyrene lay in Baden-Württemberg is of more than local significance, because the conventional association between Celts and the Danube valley in the Late Hallstatt period entirely depends on it so far as written evidence is concerned.Footnote 8 This was already clear in the influential Manuel d’archéologie préhistorique et celtique of Déchelette,Footnote 9 who noted that Herodotus was one of only two written sources for the whole area. The other was Hecataeus (c 560–480 bc), said by Stephanus of Byzantium (in the sixth century ad) to have referred to a ‘Celtic polis’ called Nyrax. Déchelette and others tentatively connected the name Nyrax with the vaguely similar Noreia in Noricum (approximately Austria and part of Slovenia), but that guess is now generally rejected.Footnote 10 The most recent suggestion, that Nyrax lay in Portugal,Footnote 11 is also a guess.
As far as written sources go, labelling sixth- or fifth-century Baden-Württemberg and areas to its east as ‘Celtic’ now depends on equating the Heuneburg with Herodotus’s Pyrene.Footnote 12 If this equation is incorrect, we have no contemporary written evidence for Celts in southern Germany during the Early Iron Age (ie before c 450 bc). This is why cautious students of the ‘West-Hallstattkreis’ now tend to say that this area is ‘often referred to as “early Celtic”, suggesting tentative connections to later cultural phenomena’.Footnote 13 Similarly, recent French archaeologists and ancient historians, surveying middle Europe in the Early Iron Age (800–450 bc) ‘before the historical Celts’, consistently avoid the adjective ‘Celtic’, despite frequent reference to the Heuneburg.Footnote 14
A RECENT DEFENCE OF THE CELTICITY OF THE HEUNEBURG
At one time, Dirk Krausse, a distinguished and prolific authority on the archaeology of Baden-Württemberg, agreed that ‘we cannot be certain that the Heuneburg was the polis of Pyrene’.Footnote 15 Now, however, he supports the equation, advancing two new arguments, which will discussed below, and defends the use of ‘Celtic’ in Hallstatt-period archaeology on more general grounds.Footnote 16 One of these grounds is that:
Not only in museums and the media, but also in international scientific competition for publication and third-party funding, terms like ‘Celts’ or ‘Celtic’ may be more attractive than anonymous prehistoric terms such as Hunsrück-Eifel-Culture, Northwest Alpine Zone of the Late Hallstatt Culture, or La Tène Culture(s).Footnote 17
Another is that:
In any case, if archaeology truly wants to be and remain the leading discipline of Celtic Studies, it can hardly do without the concept of the Celts.Footnote 18
Revisionism, Krausse argues, has undermined Central European prehistoric research:
Unnoticed by wide sections of German-language research, the international discussion about the origins of ‘Celtic’ has meanwhile, in some respects, developed in a direction that radically calls into question the findings and doctrines of Central European prehistoric research. […] Publications claiming to prove the origins of the Celts in different regions of Europe, based on supposedly hard scientific facts, are proliferating.Footnote 19
Mentioning the ‘shaky hypotheses’ (wackligen Hypothesen) of numerous outsiders, especially in Britain,Footnote 20 he regrets that German-language Iron Age research ‘seems to have lost interpretative sovereignty over its own subject matter some time ago, as the major narratives on the topic of “Celts” and “Celtic” are now produced by others’.Footnote 21
Unfortunately, in his zeal to defend the autonomy of ‘Central European prehistoric research’, Krausse misrepresents the views of its imagined opponents.
As an example, I take my own paper ‘An alternative to “Celtic from the East” and “Celtic from the West”’.Footnote 22 This was well-received by archaeologists;Footnote 23 Krausse, however, objects to my:
raising the question of whether Germanic rather than Celtic was spoken at the Heuneburg (Herbertingen-Hundersingen, Sigmaringen district, Germany) in the sixth century bc,[ Footnote 24 ] although in the same passage he supports the opinion that the Germanic languages only developed around 500 bc. Here one only need note that the heuneburg was already abandoned as early as the first half of the fifth century bc.Footnote 25
That would indeed be nonsense, but what I actually wrote was quite different:
If a linguistic label really had to be attached to the ‘eastern Hallstatt culture’, Anreiter’s ‘Eastern Alpine Indo-European’ would be preferable both to ‘Celtic’ and even more so to ‘Germanic’, recently suggested by Renfrew (Reference Renfrew, Koch and Cunliffe2013, 216) when rightly questioning whether ‘the Hallstatt chiefs of the Heuneburg in the 6th century bc […] spoke a Celtic language at all’.Footnote 26
And the quoted opinion about Germanic not coming into existence much before 500 bc Footnote 27 was due to Mallory et al,Footnote 28 not to me. The confusion is all Krausse’s. He continues:
When, for example, the Heuneburg is classified as belonging to the ‘eastern Hallstatt culture’,[ Footnote 29 ] this falls short of the bare minimum of archaeological knowledge expected even of a linguist, especially when formulating theses of such considerable scope.Footnote 30
In fact, I was referring to Austria and Hungary on page 515, not to the Heuneburg, as readers can verify for themselves.
Krausse, citing Déchelette,Footnote 31 says that I wrongly accuse Déchelette ‘of having interpreted the entire Hallstatt culture as Celtic’.Footnote 32 In fact, I was referring to scholars in ‘the mid nineteenth century’,Footnote 33 and gave a cross-reference to a paper, cited by Krausse, where I noted Déchelette’s contrary opinion, citing those precise pages, 571 and 602.Footnote 34
Krausse’s criticisms of other scholars seem to be intended to discourage readers from bothering to read the sceptics for themselves. A context is suggested by the following paragraph, where he quotes Thomas Paulsen:
It is entirely incomprehensible that there are still Greek scholars or ancient historians who ‘partly amused, partly irritated, turn up their noses at the […] attempt by some archaeologists to equate the Celtic settlement of Pyrene, mentioned by the Greek historian Herodotus, […] with the Heuneburg in Upper Swabia’.[ Footnote 35 ] Polemics and interdisciplinary ignorance, however, will hardly be able to permanently halt […] the progress of knowledge in prehistoric archaeology.Footnote 36
THE TWO NEW ARGUMENTS FOR THE HEUNEBURG’S CELTICITY
Polemics aside, Krausse makes two new points in favour of Pyrene being Heuneburg.
The first is that the Heuneburg, as one of the most important political and economic centres north of the Alps in the sixth/fifth centuries bc, particularly deserved the Greek accolade of being called a polis.Footnote 37 This argument overlooks the fact that, when Greek writers in the time of Hecataeus and Herodotus deal with ‘barbarian’ territory, polis need not refer to more than a ‘town’. This was already pointed out in a paper published in Stuttgart in 1997.Footnote 38 Herodotus’s Pyrene, if it ever existed, was not necessarily an important place like the Heuneburg.
Krausse’s second point is more complicated, but a detailed discussion will cast indirect light on how Herodotus and then Aristotle came to hold their erroneous ideas about the length of the Danube.
His argument is based on a reference to Pyrene in a late fifteenth-century Cretan copy of the scholia on Apollonius of Rhodes’s third-century bc Argonautica.Footnote 39
According to the fantastic geography of Apollonius’s poem, the waters of the Danube descend from the northern Ocean past the semi-mythical Rhipaean mountains – these were traditionally located somewhere in the north-east of Europe (fig 1).Footnote 40 Reaching the borders of the Thracians and Scythians, one branch of Apollonius’s Danube turns east to the Black Sea while the other turns west to the Adriatic.Footnote 41 The existence of this imaginary Black Sea–Adriatic sea-passage to the Mediterranean was a common misconception in antiquity.Footnote 42 The Argonauts take this route along the Danube from its Black Sea mouth and down to the Adriatic.Footnote 43 Next, after sailing about in the Adriatic, they sail up the Po to its (imaginary) three-way confluence with the Rhône and with an unnamed third river that flows westwards to the ocean in the far west.Footnote 44 From this confluence they follow the Rhône through unidentified (Swiss or Italian?) lakes ‘in the land of the Celts’, avoiding a perilous further branch that would lead past ‘the Hercynian peak’ to the Ocean; if suggested by a real river,Footnote 45 this perilous branch may be the Rhine, or even the Seine. Finally, they proceed down the Rhône, past Celts and Ligurians, to the Tyrrhenian Sea.Footnote 46

Fig 1. Long description
A map depicting the fantastic geography of Apolloniusʼ poem, showing the Danubeʼs descent from the Northern Ocean past the Rhipaean Mountains. The map includes various rivers, lakes, and geographic features labeled with their names. Key locations include Heuneburg, Hallstatt, Belgrade, and the Celtic Lake(s). The map also shows the Atlantic Ocean, Mediterranean Sea, Adriatic Sea, Tyrrhenian Sea, and the Black Sea. The Rhipaean Mountains are located in the northeast. The Danube River flows from the Northern Ocean, passing through Scythia and Thrace. The map also highlights the Celtic Sea (Gulf of Lion) and the Po River. The map uses lines to indicate the flow of rivers and arrows to show direction. The map is a blend of real and imaginary geography, illustrating the mythical and historical understanding of the region during the time of Apolloniusʼ poem.
The oldest text of the scholia on ApolloniusFootnote 47 quotes On Ports, the lost early fourth-century bc work of Timagetus, as having stated that the waters of the Danube descend from ‘the Celtic mountains’ (not the Rhipaean mountains) ‘in the land of the Celts’ (Gaul?) and flow into ‘the Celtic lake’ (λíμνη), from which one branch flows into the Black Sea and the other into ‘the Celtic Sea’ (θάλασσα), which is an attested name for the Gulf of Lion.Footnote 48 Timagetus’s Argonauts exit via the latter branch ‘to Tyrrhenia’ (ϵἰς Τυρρηνíαν) – evidently going down the Rhône, as in Apollonius.Footnote 49 Although the entry in the scholia concludes by saying that Apollonius followed Timagetus, there is an important difference: Timagetus’s Danube seems not to flow into the Adriatic, but goes the whole way from the Black Sea to the Tyrrhenian Sea, via the Danube and Rhône.Footnote 50 This doctrine, that the Danube turned into the Rhône, would be taught much later by Theodore of Tarsus (ad 602–90), the Greek archbishop of Canterbury.Footnote 51
Timagetus’s geography is even vaguer than Apollonius’s; his ‘Celtic lake’ vaguely resembles Apollonius’s lakes ‘in the land of the Celts’, but there is no hint as to its location.
Rather than following the older ms L on Timagetus, Krausse cites the late fifteenth-century ms P,Footnote 52 as partially quoted and translated by Howald and Meyer.Footnote 53 The recension found in ms P may have been composed as late as c 1300–1475,Footnote 54 and is generally regarded as inferior to that in ms L, having a tendency to abbreviate, simplify and smooth out difficulties in a cavalier manner.Footnote 55
Whereas ms L says that according to Timagetus one branch of the Danube flowed from ‘the Celtic lake’ into the Black Sea and the other into the ‘Celtic Sea’ (the Gulf of Lion),Footnote 56 and that the Argonauts took the latter branch ‘to Tyrrhenia’ (ϵἰς Τυρρηνíαν), ms P reverses the order of the Black Sea and the Celtic Sea branches and has the Argonauts sailing ‘upstream’ from the Black Sea branch ‘to Pyrene’ (ϵἰς Πυρήνην), from where they sail through the other mouth into ‘the Celtic Sea’ – with no mention of Tyrrhenia.Footnote 57 Although Krausse wants ms P’s Pyrene to be the Heuneburg and suggests that ‘the Celtic lake’ might be Lake Constance,Footnote 58 south of the Danube, an identification rejected by Delage,Footnote 59 it is far more likely that the introduction of Pyrene is due to medieval awareness of the Pyrenees or to a scholarly memory of Pyrene in Herodotus and/or Aristotle.Footnote 60 Quite possibility P’s ϵἰς Πυρήνην is due to misreading L’s ϵἰς Τυρρηνíαν, for Wendel notes confusion between initial Π and Τ elsewhere in ms P.Footnote 61
HERODOTUS’S PYRENE RECONSIDERED
Timagetus and Apollonius do help us is in providing a plausible context for Herodotus’s ideas about the great length of the Danube, for Herodotus was well acquainted with stories about the Argonauts.Footnote 62
Discussing the (supposedly) transcontinental length of the Nile, Herodotus opines,Footnote 63 illogically, that its length in Africa is similar to the (supposedly known) length of the Danube in Europe, which (he says) flows through Europe from the polis of Pyrene, in the land of the Keltoi, who, with the exception of the Kynetes/Kynesioi (in Portugal),Footnote 64 are the most westerly people in Europe, living beyond the Pillars of Hercules (the strait of Gibraltar) – therefore somewhere near the Atlantic Ocean.Footnote 65 Surely, then, Herodotus’s Pyrene, unlike the Heuneburg, lay in the far west of Europe and he was mistaken about the length of the Danube.
His mistake is understandable in view of the statement by Strabo that the source of the Danube was unknown until Tiberius came across it, a day’s march from Lake Constance, in 15 bc.Footnote 66 That earlier Greek geographers did not know its true source is confirmed by Aristotle’s statement,Footnote 67 possibly improving on Herodotus, that Pyrene is a mountain towards the west in Celtica, from which the Danube flows across Europe to the Black Sea and from which, conversely, the Tartessus (Guadalquivir) enters the ‘sea outside the Pillars of Hercules’ (ie flowing into the Atlantic).Footnote 68
The Guadalquivir does not really reach as far as the Pyrenees, any more than the Danube does, but Aristotle’s scenario has a certain plausibility, bearing in mind the imaginary transcontinental rivers in Timagetus and Apollonius, especially the former’s Danube–Rhône and the latter’s Danube–Adriatic. Further examples of such rivers include the Nile linking the Mediterranean and the Atlantic Ocean (known to, but rejected by, Herodotus 2.21) and the Danube apparently flowing into the Loire according to Pseudo-Scymnus, c 135 bc.Footnote 69 Such transcontinental rivers did not really exist, but the use of land bridges to enable traders to move from river to river may have fostered the notion that they did.Footnote 70
The occurrence of the name Pyrene in Herodotus and Aristotle is most simply explained by the assumptions that their source(s) associated Celts with the area of the Pyrenees and that they supposed that the Danube reached the Pyrenees. It is not immediately clear whether their Danube was supposed to meet the Pyrenees (a) near their northern, Atlantic end, perhaps via a river such as the Ariège or the GaronneFootnote 71 or the Adour,Footnote 72 or (b) near their southern, Mediterranean end, perhaps via the Rhône. Krausse’s objection that Aristotle cannot have believed in waterways crossing France, because rivers such as the Saône-Rhône would obstruct them,Footnote 73 may attribute more precise knowledge to the philosopher than he really possessed. (He was clearly unaware that the Ebro would prevent the Guadalquivir reaching the Pyrenees.)
The merits of a northern versus southern Pyrenean location for the ‘Danubian’ Celts of Herodotus and Aristotle have been discussed in detail elsewhere.Footnote 74 Both are possible: (1) Apollonius’s imaginary east–west river flowing between the supposed Po/Rhône confluence and the western Ocean (4.630) might well meet the Atlantic somewhere near the northern Pyrenees; (2) alternatively, the Danube–Rhône waterway of Timagetus and Theodore of Tarsus would suit a south Pyrenean location, for Aeschylus and ‘historians of former times’ thought that the Rhône reached Iberia, as noted by Pliny (37.11.32) and Strabo (3.4.19).Footnote 75 Pliny himself (3.4.33) thought that Rhoda (Ciutadella des Roses) in Spain took its name from the Rhône (Rhodanus).Footnote 76 Moreover, Herodorus of Heraclea (c 400 bc) recorded the presence in southern Iberia ‘up to the Rhône’ of Kelkianoi – an ethnonym that looks suspiciously like a slip for Keltianoi.Footnote 77
Early Greek geographers such as Ephorus in the fourth century bc and Eratosthenes in the third wrongly supposed that the Celts possessed most of Iberia.Footnote 78 Herodotus may well have thought the same, for he only mentions Celts, Tartessians and Cynetes in the Peninsula. From this perspective, his Pyrenean Celts could easily be supposed to inhabit territory all the way from western France to ‘beyond the Pillars of Hercules’.
CONCLUSION
This fresh scrutiny of the relevant texts has shown that there is no good reason for locating Herodotus’s Pyrene at the Heuneburg, or indeed Pfohren or anywhere else in or near Baden-Württemberg. Here ‘Celtoscepticism’ undermines cherished opinions. Scrutiny, however, can also refute ‘Celtosceptic’ opinions. For example, the longstanding ‘Celtosceptic’ opinion that no ancient author ever referred to Keltoi in BritainFootnote 79 has been undermined by a reconsideration of what Hipparchus says about Pytheas.Footnote 80 Perhaps, then, further examination of ancient texts will finally reveal a reference to Keltoi in southern Germany or Austria in the fifth or sixth centuries bc. Or possibly ancient DNA and isotopic studiesFootnote 81 will reveal significantly close relationships between social groups in Baden-Württemberg and ones in areas further west that are more securely labelled ‘Celtic’.
Until that time, the ethnic and linguistic situation at the Heuneburg in the sixth and fifth centuries must be regarded as simply ‘unknown’. Even if one wanted – which I do not – it would be impossible to prove that Celtic was not spoken in Baden-Württemberg at that period. Before giving Celtic the benefit of the doubt, however, we must remember that (a) beside languages known to modern scholarship by ethnic names such as ‘Celtic’ and ‘Raetic’, there existed others, possibly many others, such as ‘Eastern Alpine Indo-European’, inferred from toponymy,Footnote 82 and (b) conventional ethnological and archaeological assumptions about Celticity in Early Iron Age Central Europe all depend ultimately either on antiquarian interpretations of a few authors such as Herodotus or on projecting later evidence backwards.
To label the Heuneburg as ‘Celtic’ solely on archaeological grounds, without any linguistic or textual evidence, would be too confusing: the general public, and most students of ‘Celtic studies’, expect a ‘Celtic’ hillfort to have something to do with people independently labelled ‘Celts’ by historians and/or linguists. ‘Celtic’, at least in studies of the ancient world, does not have an arbitrary art-historical meaning comparable to, say, ‘Gothic’ in ‘Gothic architecture’. If such an ahistorical meaning were ever accepted in Celtic archaeology, it could not aspire to be ‘the leading discipline of Celtic Studies’.Footnote 83 This is why Krausse understandably attaches such importance to locating Pyrene in Baden-Württemberg.
It might be argued that the Heuneburg can still be marketed as a ‘Celtic city’ because its residents shared some customs and material characteristics with known Keltoi and/or Celtic-speakers elsewhere. That is a slippery slope. Krausse offers Polybius’s Veneti as a good example of an ethnic group that resembled Keltoi culturally, but differed in ethnonym and language:
The part of the plain [of the Po] near the Adriatic never ceased to be in the possession of another very ancient tribe called Veneti, differing slightly from the Celts in customs and costume and speaking another language.Footnote 84
‘In such cases,’ Krausse notes, ‘one could also use the term “Celtoid”.’Footnote 85 How useful would this be? And how would the general public, the media and funding bodies react if the Heuneburg were marketed as ‘Celtoid’? It is surely better to label it ‘Early Iron Age’, pending the discovery of more precise evidence. It can stand on its own spectacular merits, without borrowing the name Pyrene from Herodotus.
