Ancient Britain and the Invasions of Julius Caesar

I. THE CASSITERIDES

I. The identity of ‘the tin-islands’, which ancient writers called the Cassiterides, is still a matter of dispute. Professor Haverfield, indeed, has affirmed that ‘the recent researches of Usener [for which read Unger], Rhys, and others, have made it almost certain that the Cassiterides were off N.W. Spain’.[2249] Professor Rhys shall speak for himself. ‘M. Reinach,’ he says,[2250] ‘argues, convincingly as it seems to me, that the Cassiterides meant the Celtic islands, or, as I may call them, the British Isles.’ And, if anything relating to this question is certain, it is that the islands off North-Western Spain, which are supposed to have been the tin-islands, have never produced any tin at all.[2251]

One group of scholars insists that all the ancient writers who mentioned the Cassiterides associated them with Spain. But what if the ancient writers were misinformed, or misunderstood their informants? Another group insists that for the metallurgists of ancient Europe the sole source of tin was the British Isles; and with this pronouncement they would apply the closure to the debate. But the British Isles were not the sole source;[2252] and the debaters persist in wrangling. If the only question were, From what parts of Europe did the Greeks and Romans derive tin, it could be answered in a sentence:—from Galicia in Spain, Cornwall, and, possibly, the Scilly Islands.[2253] But this is not the only question. What we want to know is, Were the ancient writers misled into believing that the Cassiterides were islands? If they were not misled, were they all thinking of the same islands? Or did they attempt to indicate the position of the Cassiterides by simply guessing? If they were misled, was the district to which their informants alluded Galicia or Cornwall, or did they refer to both? Did the ancient writers fancy that islands used as depots for tin were the places in which the mines were situated? Did those who professed to inform them intentionally mislead them?

The theories which have recently held or still hold the field are, first, that the Cassiterides were a group of islets off the north-western coast of Spain; secondly, that they were headlands of the same coast; thirdly, that they were the Scilly Islands; fourthly, that they were Cornwall, which is supposed by some writers to have been regarded either as an island or as a group of islands, separated by estuaries, which were erroneously believed to be channels; and, lastly, that they were the British Isles.[2254]

II. Diodorus Siculus,[2255] after stating that tin was produced in Britain and in many parts of Iberia, goes on to say that there are many tin mines in the islands called Cassiterides, which are situated in the ocean, off the coast of Iberia and above the country of the Lusitani.[2256] Strabo mentions the Cassiterides four times. In the first passage[2257] he says that the extremity of the Pyrenees is opposite the western parts of Britain, and that the Cassiterides, which are situated in the same latitude as Britain, are in the open sea, opposite to and north of the Artabri. In the second[2258] he mentions both the Cassiterides and the British Isles, clearly distinguishing the two groups. In the third[2259] he says that, according to Posidonius, tin was produced in the country beyond [that is to say, north of] the Lusitani, and also in the Cassiterides; that tin was conveyed from the British Isles to Massilia, and that, according to the same authority, tin, silver, and gold were produced in the country of the Artabri, the most remote tribe of Lusitania, who face the north-west. In the fourth[2260] he says that the Cassiterides are ten in number and lie close together in the open sea, north of the harbour of the Artabri; that one of them is uninhabited; and that the inhabitants of the rest wear black robes reaching down to their feet, and walk about with staves in their hands, ‘like the Furies in tragedy.’ They are, he says, nomadic, and live upon flesh meat; and they barter tin and hides with merchants for pottery, salt, and articles of bronze. Formerly, he adds, the Phoenicians monopolized the trade from Gades, or Cadiz, with the islanders; and they kept the route a close secret, which, however, the Romans, after numerous attempts, succeeded in discovering. Finally, Publius Crassus sailed across (διαβάς) to the islands, ascertained that the tin lay near the surface, and indicated the route for the benefit of traders, ‘although the passage was longer than that [from the continent] to Britain.’ In another passage[2261] Strabo says that the Artabri dwell in the neighbourhood of the north-western promontory of Iberia, which he identifies with the Nerian promontory.[2262] Pomponius Mela,[2263] himself a Spaniard, immediately after speaking of Baetica and Lusitania, and immediately before mentioning the island of Sena, which was off the coast of Brittany, states that the Cassiterides are situated in Celticis. Pliny[2264] says that the Cassiterides, so called from the abundance of tin which they produce, are situated over against Celtiberia, and that opposite the promontory of the Arrotrebae are ‘the six islands of the Gods’, which some call ‘the Fortunate Isles’. In another passage[2265] he says that tin was first fetched from ‘the island Cassiteris’ (or from ‘the tin island’) by Midacritus, whom M. d’Arbois de Jubainville,[2266] wrongly, according to M. Salomon Reinach,[2267] identifies with ‘Melkarth, who personified the Phoenician race’. In a third passage[2268] Pliny says that tin has been fabulously reported to have been obtained from islands in the Atlantic. ‘Now,’ he continues, ‘it is certainly known to be produced in Lusitania and Galicia.’ By ‘islands in the Atlantic’ Pliny certainly did not, as Professor Ridgeway supposes,[2269] consciously mean the British Isles; for in his geographical system the northern limit of the Atlantic was marked by the north-western promontory of Spain.[2270] Ptolemy[2271] says that the Cassiterides are ten in number, and are situated in the western Ocean. Finally, Dionysius Periegetes[2272] says that ‘the western isles’, which produce tin, and are situated below the Sacred Promontory, or Cape St. Vincent, are inhabited by Iberians.

From a comparison of these statements it is clear, first, that the ancient geographers who mentioned the Cassiterides regarded them as distinct from the British Isles; secondly, that they believed them to be situated somewhere off the coast of Spain (although, as we shall presently see, the words of Strabo are not inconsistent with the theory that he identified them with the Scilly Islands, or even, unconsciously, with the British Isles); thirdly, that of those who attempted to define their position one associated them with the south-western, the others with the north-western coast; fourthly, that one writer mentioned an island, Cassiteris, from which tin was fetched; and, lastly, that this same writer, having affirmed that the tin islands were opposite Celtiberia, nevertheless denied that any islands in the Ocean which extended as far north as the north-western promontory of Spain produced tin.

III. Assume, for the sake of argument, that the Cassiterides were off the north-western coast of Spain. What, then, are the islands with which they are to be identified?

1. Unger[2273] remarks that it may be inferred from Ptolemy’s statement that they were south of the Nerian promontory and off the western coast of Galicia. Strabo, it is true, places them northward of the northern coast: but, says Unger,[2274] Strabo is wrong; for on the northern coast there are no islands distant more than one German mile [or between four and five English miles] from the shore, whereas Strabo himself says that the Cassiterides were further from the continent than Britain. Dionysius Periegetes was, by common consent, mistaken. Let us see then what islands we can find off North-Western Spain. The coast between Cape Ortegal and the mouth of the Douro is broken by several inlets or fiords, which are called Rias. East of Cape Finisterre, in the Ria de Corcubion, are three very small islands; and off the south-eastern entrance of this Ria, by Cape Minarzo, are six tiny islets. About 20 miles south-east of Cape Finisterre is the Ria of Muros and Noya: on the west of Mount Louro, which dominates the entrance of this fiord on its northern side, are the four small islands of Bruyos; and there are others within the fiord itself and south of it. Unger[2275] remarks that the small size of all these islands harmonizes with the word νησῖδες, or ‘islets’, which Diodorus applies to the Cassiterides; and that the smallest of them may have been left out of account when the number was given as ten. Off Pontevedra Bay, which is north of Vigo Bay, are the islands of Ons and Orcela.

Strabo says that the harbour of the Artabri, north of which he places the Cassiterides, was formed by a gulf on which were situated numerous cities.[2276] Mela[2277] describes a gulf in the country of the Artabri as having a narrow entrance and a wide circuit, and adds that four streams flowed into it; and Ptolemy,[2278] having first mentioned a harbour of the Artabri, immediately south of the Nerian promontory, speaks, in the next section but one, of ‘the Great Harbour’, on the shore of which he places Brigantium. The gulf mentioned by Mela and Ptolemy’s ‘Great Harbour’ correspond with the Ria of Betanzos and Ferrol, which is between Cape Finisterre and Cape Ortegal; but there are no islands north of this harbour. The identification of the harbour of the Artabri which Ptolemy places immediately south of the Nerian promontory depends of course upon the identification of the promontory itself. The latter is generally identified with Cape Finisterre; and if this view is correct, the harbour must have been the Ria de Corcubion. Unger, however, identifies the Nerian promontory with the bluff of land, between Cape Finisterre and Corunna, from which project the headlands of Punta del Roncudo, Punta de Nariga, and Cape de S. Adrian;[2279] and if he is right, Ptolemy’s harbour was the Ria of Corme and Lagos. But, as Unger points out, there are no islands off this harbour or north of it.[2280] It is clear, then, that if the Cassiterides really lay in Spanish waters and on the north of a harbour of the Artabri, that harbour must be looked for further south. Now Unger[2281] observes that Posidonius, as quoted by Strabo,[2282] makes the territory of the Artabri extend southward as far as the river Douro; for he says that their territory produced gold; and, says Unger, in the country of the Artabri, in the narrower sense, there are no auriferous streams. Accordingly, Unger identifies the harbour for which he has been searching with the Puerto de Bayona,—the southernmost inlet north of the Douro; and from this harbour he maintains that Crassus sailed to the Cassiterides, which he identifies with the islands of Bruyos. He points out that the distance from the northern entrance of the harbour, opposite the island of Bayona, to the islands of Bruyos is eight German miles. This distance exceeds that of the shortest passage between Britain and the continent; and accordingly Unger insists that it harmonizes with the statement of Strabo. But the point which he most strenuously labours is that ‘in this case only is explicable the circumstance, strikingly calculated to cause such a mistake as Strabo made, that Crassus sailed northward from a harbour on the west coast [of Galicia], and yet sailed in the open sea’.[2283]

Mr. Cecil Torr,[2284] on the other hand, insists that ‘unless it can be shown that there were tin mines on the islands [near Vigo], the story [of the voyage of Crassus] cannot be used to show that Crassus visited those islands’. Strabo, he adds, states precisely that the Cassiterides ‘lay to the north of Ἀρτάβρων λιμήν’, which ‘is obviously the gulf that now holds Ferrol and Corunna’. Here, as we have seen, there are, in Spanish waters, no islands; and Mr. Torr argues that ‘Strabo is so very accurate in his description of this part of Spain that his account of the Cassiterides cannot be explained away as an inaccurate description of the islands at Vigo.... It must be a bit of downright fiction repeated in good faith.’[2285] To this latter argument it might be replied, first, that just as Strabo was mistaken in supposing that the direction of the Pyrenees was from north to south, so he may have been mistaken in supposing that the Cassiterides were on the north of Spain; and, secondly, that the other writers whose testimony has been quoted place them off the west coast. No other reply, indeed, could be made by those who hold, like Unger, that the Cassiterides were in Spanish waters. But, for reasons which shall presently be given, I agree with Mr. Torr that Ἀρτάβρων λιμήν must have been ‘the gulf that now holds Ferrol and Corunna’, and also that Strabo’s ‘account of the Cassiterides cannot be explained away as an inaccurate description of the islands at [or rather near] Vigo’. Only I believe that he is wrong in regarding that account as ‘fiction’. Strabo’s Cassiterides were not in Spanish waters at all: they were, as he says, in the open sea, and far to the north of Corunna. Mr. Torr’s other objection rests upon the fact that tin was never produced in any island off the coast of Spain, except, possibly, in Ons,[2286] which, for reasons obvious to any one who consults the map of Spain, Unger does not include among the Cassiterides. The only possible answer to this objection has been already suggested in this article: it is that the islands may have served as depots to which the tin was conveyed from the mainland opposite, and that they may have been confounded with the districts in which the tin was actually produced. This suggestion, however, leaves unexplained the definite statement of Strabo, that Crassus sailed across to the islands and found that the islanders worked the tin easily because it lay near the surface. There remain three other objections, which, unless Strabo’s authority is to be absolutely discarded, appear insuperable. First, Strabo, I repeat, distinctly states that the islands were ‘in the open sea’ (πελάγιαι); and of the islands which Unger identifies with the Cassiterides not one is more than four statute miles from the mainland, while the nearest is not more than two. Secondly, as they are all within sight of land, their situation could never have been kept secret. Lastly, since it was unnecessary for those who desired to reach them to sail from the harbour of Vigo, and easy to sail across from the neighbouring Ria of Muros and Noya, it is difficult to understand why Strabo should have said that the distance which separated them from the mainland was greater than the distance from Gaul to Britain. It is true that the islanders, according to Strabo, dressed in black, and that, according to the same authority,[2287] the inhabitants of Lusitania did likewise; but any one who regards this as an argument for identifying the Cassiterides with the islands near Vigo must make up his mind to reject nearly all the details which are given by Strabo, and to pin his faith to the undoubted fact that the Cassiterides are placed by most of the ancient authorities off the coast of Spain. M. Salomon Reinach, however, with whom I agree, argues that ‘the fact that numerous [ancient] writers place the Cassiterides in geographical connexion with Spain only proves—what we knew before—that Phoenician Spain had commercial relations with those islands’.[2288]

2. M. Hans Hildebrand[2289] thinks that the Cassiterides were headlands of the Galician coast. He argues that if they are to be located ‘in England’, the name Cassiterides must be applied to headlands in Cornwall; accordingly, he says, ‘je demande la même concession pour ma théorie espagnole, savoir que ce nom désigne des caps.’[2290] But Cornwall is part of an island which is itself one of a group of islands: Spain is not an island at all. M. Hildebrand’s theory can by no ingenuity be defended except on the assumption that the ancient writers were misled by the fact that in the language of the Phoenicians, from whom the earliest notions about the Cassiterides may be supposed to have been derived, there was no word which specially denoted islands; and if it is accepted, not only must all the statements of those writers which relate to the situation of the islands, their number, their inhabitants, the mode in which the tin was extracted, and the voyage of Crassus, be rejected as absolutely fictitious, but it is utterly impossible to conceive how they should have originated.[2291]

3. The old-fashioned view, which identified the Cassiterides with the Scilly Islands, has even of late years had adherents of high reputation, such as Dr. von Gutschmid,[2292] Emil Hübner,[2293] and Mommsen.[2294] Although the bulk of the tin which supplied the wants of ancient Europe came from Cornwall and Spain, it is nevertheless not improbable that some came from the Scilly Islands.[2295] If so, the real Cassiterides were the Scilly Islands and ‘the adjacent island’ of Great Britain. But of the ancient writers there were only two of whom it can be maintained that when they referred to the Cassiterides they were thinking either of the Scilly Islands or of Cornwall,—Festus Avienus and Strabo.

Festus Avienus was a writer of the fourth century, whose Ora maritima was based either upon a Greek version of the Carthaginian account of the voyage of Himilco,[2296] or, as seems more probable, upon a Greek poem, which had itself been compiled from two distinct Greek narratives of different dates, the latter being assignable to the period between 240 and 150 B.C.[2297] After describing the rocky peninsula, Oestrymnis, he says that in the gulf formed by it lie the islands called Oestrymnides, which are widely scattered and rich in tin.[2298] He does not mention the Cassiterides at all. The Oestrymnides, however, are generally, and, if Festus was right in saying that they produced tin, necessarily identified with the Cassiterides: the peninsula is rightly identified with Brittany,[2299] or, more strictly speaking, with the promontory formed by Finistère; and therefore the gulf is either the Bay of Biscay, or the gulf in which lie the Channel Islands. After describing the Oestrymnides, Festus goes on to say that ‘from here it is two days’ sail to the Sacred Island’, that is to say, Ireland (hinc duobus in sacram sic insulam Dixere prisci solibus cursus rati est[2300]); and then, remarking that ‘the island of the Albiones’, or Britain, is near, he says that the Tartesii used to resort for trade to the Oestrymnides, and that the Carthaginians also used to sail ‘these seas’.[2301]

The question of the identity of the gulf is discussed by Friedrich Marx in an article on the Ora maritima,[2302] of which a summary has been given by Mr. W. H. Stevenson.[2303] Marx, says Mr. Stevenson, ‘explains the sub vertice [of the promontory or peninsula, Oestrymnis] of Avienus[2304] as referring to the maps of antiquity, and as having the sense of “northwards of”, so that the Tin Islands are conceived of as north of the promontory of Finistère.... The Tin Islands must therefore be the mainland of Britain and the Isle of Wight (which Marx considers to be included among the laxe iacentes insulae of Avienus), and cannot be explained as the Scilly Islands, which have nothing beyond their insular nature to favour the identification.’ But why ‘therefore’? What has the Isle of Wight beyond its ‘insular nature’ to ‘favour the identification’? If Marx is right in his interpretation of sub vertice, the gulf (sinus) lay north of ‘the promontory of Finistère’; and since it can hardly be maintained that this gulf was the English Channel, it must have been the gulf in which lie the Channel Islands. If it was the English Channel, Marx can hardly venture to argue that ‘the mainland of Britain’ is in the Channel. If any conclusion can be drawn from the words of Festus, it must be either that the laxe iacentes insulae were the Channel Islands and the sinus the gulf in which they are situated, or that the sinus was the Bay of Biscay and the insulae Ushant and the adjacent islets. But I agree with Mr. Stevenson that ‘the Tin Islands [of Avienus] ... cannot be explained as the Scilly Islands’, unless the indications which Avienus gives of their situation are utterly misleading.

Strabo, as we have seen, says that the Cassiterides were in the open sea northward from the harbour of the Artabri; and Mr. H. F. Tozer[2305] argues that, according to Strabo’s ‘idea of the relative position of these countries [Spain and Britain] this would place them a great distance to the west of the Scilly Islands’. This objection, however, assumes that Strabo was aware that the Scilly Islands were comparatively close to the Land’s End. Strabo imagined that the direction of the Pyrenees was from north to south; that the coast of Gaul extended in a straight line from the northern extremity of the Pyrenees to the mouth of the Rhine; and that the southern coast of Britain extended from a point nearly opposite and close to the northern extremity of the Pyrenees, parallel with the coast of Gaul.[2306] He expressly states that the Cassiterides were in the same latitude as Britain; and therefore, if he had intended to identify the Cassiterides with the Scilly Islands, it would have been quite natural for him to say that they lay north of the harbour of the Artabri.[2307] Müllenhoff[2308] indeed dismisses the claims of the Scilly Islands with contempt; but all that he has to say against them is that they never produced tin, and that they are small. The former objection is, as we have seen, unfounded; the latter is irrelevant, for small islands may contain mines, and the islands off the coast of Spain are smaller still.

But I am not concerned to argue that the sailors from whom the ancient writers, directly or indirectly, derived their information intended to convey that the Cassiterides were the Scilly Islands and the Scilly Islands alone; for, although the Scilly Islands did produce some tin, by far the greater part of the British supply of that metal doubtless came from Cornwall. Professor von Gutschmid indeed explains that ‘the tin was supposed [by the ancient writers] to be produced where it was exchanged,—a very common case’;[2309] and although the place where the Cornish tin was exchanged by the merchants who used the overland route was Ictis, or St. Michael’s Mount,[2310] the Phoenicians may possibly have found it convenient to occupy one of the Scilly Islands.[2311] But it seems to me safer to conclude that the Scilly Islands may have been originally included with Britain under the designation, Cassiterides.

The late distinguished geographer, H. Kiepert, maintained that although the name, Cassiterides, had been originally used by the Greeks to denote the tin-producing districts of Britain, it was erroneously applied by Strabo to the Scilly Islands. ‘Only to this group’, he insists, ‘can Strabo’s account of the discovery of the ten small Cassiterides-islands on the north of Hispania by ... Publius Crassus refer, as there are no other islands in this part of the ocean.’[2312]

4. George Smith, for whom the Cassiterides represented simply the Cornish peninsula,[2313] observed, anticipating a similar argument of Mr. Cecil Torr,[2314] that ‘the Hebrew, Phoenician, and cognate languages had no terms which distinctly specified islands, peninsulas, &c.; one word being used to signify islands, sea-coasts, and even remote countries. In these languages the whole coast of Cornwall and Devonshire might be termed island or islands.’ It may be objected that the very same argument might be used to show that the name, Cassiterides, really denoted the headlands on the coast of Galicia.[2315] But it is easier to conceive how the misconception should have arisen in the case of Cornwall, part of a remote island in the northern ocean and close to the Scilly Islands, than in the case of Galicia; and, moreover, the Galician theory leaves the story of Crassus’s voyage unexplained. But the problem of the Cassiterides cannot be satisfactorily solved by the simple statement that they were Cornwall.

5. Müllenhoff,[2316] M. Salomon Reinach, and various other writers identify the Cassiterides with the British Isles. According to M. Reinach,[2317] ‘the whole question resolves itself into this:—what islands in western Europe produce tin? The British Isles alone fulfil this condition; therefore we must recognize in them the archipelago of the Cassiterides.’ ‘If,’ he adds, ‘Strabo does not identify them with the British Isles, though he mentions both the one group and the other, this is because in the different chapters [of his work] he follows different authorities, some of whom allude to the Cassiterides from hearsay evidence collected in Spain, while the others describe the British Isles from experience derived on the spot.’ Then, remarking that the alleged derivation of κασσίτερος (the Greek word meaning ‘tin’) from a Sumerian word and from an Assyrian word have been proved to be fanciful, he argues that κασσίτερος did not, as most ancient and modern writers have supposed, give its name to the Cassiterides, but on the contrary derived its name from theirs. Similarly, he points out, at least four names of metals have been derived from the names of places which produced them, namely, copper from Cyprus; silver (in Gothic silubr) from the town of Salybe in Pontus;[2318] bronze from Brundisium; and Kalay, the Turkish word for tin, from Kalah in the peninsula of Malacca. M. Reinach goes on to argue that as the Greeks derived their knowledge of the Cassiterides from the Phoenicians, the termination ιδες must have been added by them. There remains therefore cassiteros, of which the first part is found in numerous Celtic words, for example, Cassi, Cassi-vellaunus, Velio-casses, &c. M. Reinach gives reasons, which appear to me unsatisfactory, for the conjecture that Cassiterides means the same as insulae extimae (‘the remotest isles’); and he holds that the name was given to the British Isles by the Celts of Western Gaul.[2319]

Whatever M. Reinach’s argument may be worth, he and Müllenhoff are unquestionably right in one sense: the British Isles, taken as a whole, were the only islands from which the ancients derived tin. But this truism did not require demonstration. The question is, whether the identification of the Cassiterides with the British Isles can be reconciled with what was written about them by the ancient geographers.

IV. The story which Strabo tells about Publius Crassus presents some difficulty. As we have seen, he says that after the Romans had discovered the route to the Cassiterides in spite of the efforts which the Phoenicians made to conceal it, Crassus sailed across to the islands, ascertained that the tin lay near the surface, and indicated the new route for the benefit of traders. The first question is, who was Crassus? Unger[2320] maintains that he was the consul of 95 B.C. who conquered the Lusitanians. If so, he must have sailed from the mainland to the islands near Vigo which Unger identifies with the Cassiterides. But, as I have already pointed out, these islands are quite close to the coast: their distance from the mainland is not greater, but many times less than the distance of Britain from the Continent; their whereabouts could never have been kept secret; and they have never produced tin. Therefore, if Publius Crassus was the consul of 95 B.C., Strabo’s story is utterly untrustworthy. Mommsen[2321] holds that Crassus was Caesar’s lieutenant of that name, and that he sailed from Gaul to the Scilly Islands before Caesar’s first invasion of Britain.[2322] How then are we to account for the ignorance of Caesar, who tells us that tin was produced ‘in the midlands’ (in mediterraneis regionibus[2323]) of Britain? Professor Ridgeway, who believes that the Cassiterides were the islands near Vigo, also identifies Crassus with Caesar’s lieutenant, who, as he reminds us, invaded Aquitania—the south-western division of Gaul—in 56 B.C. ‘He is all the more likely,’ writes Professor Ridgeway,[2324] ‘to have passed into Northern Spain, inasmuch as the people of that region had given great assistance to the Aquitani ... (B. G., iii, 23). Without doubt he was fully aware of the mineral wealth of that country, as is shown by Caesar’s remark (iii, 21) on their skill in defending cities, in consequence of their having numerous copper mines and other works in that region. As is plain from Strabo’s words, the Romans already knew how to reach the tin islands by sea, coasting round from the Mediterranean and up from Gades on the old Phoenician track. Crassus, then, by opening up a far shorter route, that of a short sea voyage from the Cassiterides to the coast of Gaul (possibly to the Garonne), at once developed this trade. The ore lay near the surface. The distance by sea was greater than that across the English Channel, but the readiness with which the tin was obtained, combined with the shorter land transit, more than compensated this. Strabo is evidently contrasting the rival tin-producing regions when he introduces the allusion to Britain.... From this achievement of Crassus and its results we can now understand in its proper light the famous expression of Pytheas, that “the northern parts of Iberia are more accessible towards Keltiké than for those who sail by the ocean”.... He found, as Publius Crassus found three centuries later, that the mineral regions and islands of North-Western Spain were far more accessible for the Massaliotes by a land journey across Gaul and a short sea voyage than by the long and perilous route round by Gibraltar.’ But Professor Ridgeway mistranslates ‘the famous expression of Pytheas’,—τὰ προσαρκτικὰ μέρη τῆς Ἰβηρίας εὐπαροδώτερα εἶναι [τοῖς] πρὸς τὴν Κελτικὴν ἢ κατὰ τὸν ὠκεανὸν πλέουσι.[2325] He fails to see that the word πλέουσι refers to πρὸς τὴν Κελτικήν as well as to κατὰ τὸν ὠκεανόν. The passage simply means that it is easier to sail along the northern coast of Iberia (Spain) from west to east in the direction of Keltiké (Gaul) than to sail along the southern coast from east to west in the direction of the Atlantic.[2326] This, as Müllenhoff[2327] observes, is perfectly true, owing to the set of the current and the prevalence of westerly winds. Moreover, Professor Ridgeway does not seem to be aware that there are no ‘tin islands’ off the coast of Spain: he does not explain how Crassus could have found time in 56 B.C. to make the ‘short sea voyage’ of five hundred miles or more from the mouth of the Garonne to the neighbourhood of Vigo, when he was campaigning in Aquitania until the approach of winter;[2328] nor, finally, does he explain how the Massaliotes would have gained by conveying tin five hundred miles from the neighbourhood of Vigo to the mouth of the Garonne, and then considerably more than three hundred miles across Gaul to Massilia, instead of overland across Spain. Mr. Tozer[2329] disposes of the difficulty by simply discrediting Strabo’s account. ‘There is no reason,’ he says, ‘to doubt that Crassus made such an expedition; but whatever the place was to which he went, his account is quite untrustworthy, because he represents the Cassiterides as producing tin, whereas that metal is not found in any of the groups of islands which lie off the coasts of Gaul, or Britain, or Spain. The explicit character of his statements, however, seems to have deceived his contemporaries, and Strabo among them.’ But what theory can Mr. Tozer frame to account for the gratuitous mendacity which he imputes to Crassus, who, by the way, was not Strabo’s contemporary?[2330] Strabo’s story is, in any case, obviously inaccurate:[2331] but I agree with Mr. Tozer that it contains a kernel of truth; and I can only suppose that Crassus, when he was in Brittany in 57-56 B.C.,[2332] was directed by Caesar to visit and report upon the tin-producing districts of the British Isles.[2333] And if I am asked how I account for the mistake which Caesar made when he said that tin was produced in the interior of Britain, I offer the following suggestion. Crassus may have contented himself with landing on the coast, perhaps at or near St. Michael’s Mount, where the tin was delivered to the merchants:[2334] if so, he was doubtless informed that the tin was actually won in the interior, as, in literal truth, it of course was;[2335] and Caesar may have hastily concluded from his report that the tin mines were far from the coast. As to the details with which Strabo embellished his story, it would be idle to conjecture from what source they were obtained. We may be sure that he did not invent them; but he may have confused items of information furnished by different authorities.[2336]

V. The conclusion of the matter is this. The statements of Strabo are most satisfactorily explained on the hypothesis that those from whom he, directly or indirectly, derived his information referred to the Scilly Isles and probably also the Cornish peninsula, or (which is less probable) to islands off the coast of Brittany, at which trading vessels may have touched on the voyage. All the other ancient writers, except perhaps Polybius, undoubtedly associated the Cassiterides with Spain. In so doing they were mistaken; for no islands in Spanish waters, except Ons, which is out of the question, have ever produced tin. The real Cassiterides—the ‘tin islands’ which were known to the mariners from whom the ancient writers ultimately derived their notions—were, speaking generally, the British Isles, and particularly, the tin-producing districts of Cornwall and perhaps also the Scilly Islands. It is possible that Polybius[2337] may have held this view; for he does not mention the Cassiterides, and names the British Isles as the source of tin.

How the ancients came to entertain such vague notions about the Cassiterides, is not difficult to conceive. Evidently, when they first heard of them, all that they could learn was that they were somewhere in the western ocean. Knowing that Gades was the centre of the tin trade, they would naturally assume that they were in Spanish waters[2338]; and even when they learned that tin came from Britain and from Galicia, they would cling to the idea that it came also from islands, the geographical position of which the crafty Phoenicians had striven to keep secret. Mr. Tozer[2339] may possibly be right in suggesting that ‘when the nations about the Mediterranean obtained more accurate information concerning the north-western coasts of Europe, it was natural that they should affix the name to one or other of the groups of islands with which they found the trade to be associated’. ‘Thus,’ he continues, ‘by some writers it may have been attached to the Oestrymnides, by others to the islands of the Galician coast, and even the Scillies may in some cases have been intended.’ But is it not likely that the writers in question, when they attempted to locate the Cassiterides, were not identifying them with any group of islands the existence of which was certainly known to them, and the whereabouts of which they knew? M. Salomon Reinach puts the matter well, though he fails to perceive that Strabo was not referring to islands in Spanish waters. ‘There were two traditions,’ he says, ‘relating to the tin islands,—one Phoenician, of which the starting-point was Southern Spain; the other Greek, which originated at Marseilles. With that respect for the written word which characterized them, the ancients accepted the two traditions side by side.... Even after the expedition of Crassus ... Pliny dared not reject the geographical legend which connected the islands with Spain; and a century later Ptolemy persisted in the same error.’[2340]

Mr. W. H. Stevenson explains that Müllenhoff, of whose conclusions respecting the Cassiterides he gives a lucid summary, holds that they ‘were marked by guess-work on the early Greek maps ... off the north-west coast of Spain ... and that they there remained on the maps (much like the mythical island of Brazil in fifteenth-century maps), although they had been known since the time of Pytheas, under the names of Britannia, Albion, Ierne, &c., without their identity being suspected. In a precisely similar manner the Electridae, which had been put into the maps by guess-work, were retained long after it was known that amber came from the shores of the Baltic, and not from islands in the North Sea.’[2341]

Thus the important point to bear in mind is that the name Cassiterides, which must, as Kiepert says, have been originally applied to the British Isles, was afterwards misapplied to imaginary islands, and applied by Strabo, not perhaps without some foundation in fact, to the Scilly group.
