Stonehenge has exercised the minds of many generations of antiquaries. An exhaustive bibliography, filling 169 pages and containing the titles of 947 books and articles, was published in the Wiltshire Archaeological and Natural History Magazine for 1901: but nearly all the works therein enumerated are obsolete; and any one who wishes to form an independent judgement will find all the necessary materials in the volumes which will be referred to in this article.

I. Modern opinion has for some time been tending to the conclusion that Stonehenge was erected, or at least began to be erected, in the Bronze Age. Excavation has proved that it did not exist before the use of copper or bronze, however uncommon it may have been, was known in this country;2171 and the arguments of Rickman,2172 James Fergusson,2173 and others who contend for a Roman or post-Roman date have been or can be demolished. To refute them in the text of this article would be useless; for no competent archaeologist now regards them as worth discussion.2174

Dr. Arthur Evans maintains that Stonehenge was built in the earlier half of the third century before Christ, although some parts of it may be of later date; that ‘sun worship was at most a secondary object in its structure’; and that it was ‘one of a large series of primitive religious monuments that grew out of purely sepulchral architecture’. Let us first consider the question of date.

Dr. Evans has no difficulty in establishing, what has already been demonstrated in Part I of this book,2175 that ‘Stonehenge was at least begun before the close of the Wiltshire “Round-Barrow” Period’.2176 At the same time he holds that ‘its foundation belongs to the conclusion of this period’. He points out that ‘of 36 disk-shaped barrows [in the neighbourhood of Stonehenge] 35 contained cremation interments.... The number of glass beads contained in these barrows is also,’ he continues, ‘evidence of their comparatively late date2177.... The general inference which we draw from the intimate structural connexion between Stonehenge and these disk-shaped barrows is, that the great stone circles themselves were erected towards the close of the Round-Barrow Period. The proportionately frequent occurrence of gold relics in barrows in the immediate neighbourhood of Stonehenge, 4 out of 5 such discoveries having been made within half-a-mile of this monument, points in the same direction.’ And if it should be argued that the barrows may have been built after the erection of Stonehenge, his answer would be that ‘the barrows themselves, with the exception of the two within its own area, are disposed without any reference to Stonehenge, and do not in any way cluster about it, as we might reasonably have expected them to do had the bulk of them been reared after the Stone Circle’. Dr. Evans then observes that an amber collar ‘found in one of the Lake barrows about two miles from Stonehenge ... is of a form and arrangement identical with the amber necklaces found in the great cemetery at Hallstatt, and from the similar character of the boring of the beads must in all probability have come from the same centre of manufacture’; and he endeavours to show that we may infer from recent discoveries that ‘a large proportion of the Hallstatt remains reach down to the period between the approximate dates of 450-300 B.C.’2178 On the other hand, Late Celtic antiquities, which began to appear in Britain ‘at least as early as the second century B.C.’, are absent from the barrows of Wiltshire; and the latest date which can be assigned to these barrows is about 250 B.C. Dr. Evans concludes that ‘we may approximately refer the foundation of Stonehenge to the end of the fourth or beginning of the third century’.2179

Some of these arguments do not appear to have much weight. Dr. Evans himself admits that there is a great structural distinction between Stonehenge and the disk-shaped barrows:2180 in the latter the surrounding ditch is inside the bank; in the Stonehenge vallum it is outside. Those barrows at all events in which chippings of the stones were found were later than Stonehenge;2181 and whatever conclusion may be drawn from the arrangement of the barrows, their number is so great as to suggest the inference that many of them were erected there because Stonehenge was regarded as a holy place. In a recent article,2182 however, Dr. Evans has reinforced his argument, pointing out that the circle called the Rollright Stones, which stands on a hill overlooking the valley of the Warwickshire Stour, also stands ‘in immediate relation to a large group of [disk-shaped] sepulchral barrows’, and giving additional and conclusive evidence as to the late date of these particular monuments. He would not, however, I believe, now assign to Stonehenge quite so early a date as the ‘beginning of the third century’; for the commencement of our Early Iron Age is commonly referred to about 400 B.C.2183 Of the two barrows in which Hoare found chippings of the Stonehenge stones one was bell-shaped,2184 the other belonged to the kind which he called ‘flat’,2185 but which, as Thurnam points out,2186 is simply a variety of the bowl-barrow; but Thurnam has given reasons for believing that many barrows of this form may not have been earlier than disk-shaped mounds.2187

In 1901 excavations were made at Stonehenge, but only in ‘a fraction of the whole site’, under the superintendence of Professor W. Gowland.2188 The principal objects discovered were chippings from the ‘sarsens’ and ‘blue-stones’; more than one hundred stone implements, many of which were of flint, and had evidently been used for dressing the softer stones of the monument, while others consisted of ‘the hard quartzite variety of sarsen’; bones of domestic animals; ‘splinters of antlers of deer’; ‘a portion of a large antler with its lowest tine worn away,’ apparently from its having been used as a pick; and Roman coins, which, however, were only found in the superficial layers.2189 ‘The layers of the excavations,’ says Professor Gowland, ‘in which the flint and stone tools were found was absolutely undisturbed ground’;2190 and the chippings were found as far down as the surface of the bed rock. Only one trace of copper or bronze was visible, namely a stain, described by the formula CuCO3 on a sarsen block, seven feet below the surface. The work of trimming the stones appears to have been done with stone implements only. The copper stain, however, proves that copper or bronze must have been in use at the time when the builders of Stonehenge were at work. Professor Gowland2191 affirms that the stain ‘can only have been produced by prolonged contact with some very small object of copper or bronze or some material containing copper.... It may perhaps have been an ornament, but cannot possibly have been an implement.’ He argues, further, that ‘even if metal tools were of no use for this particular work, it is difficult to believe that, if the monument were of the Bronze Age, no bronze implement would have been lost in the course of its erection’.2192 I, on the other hand, would remind him that no bronze has been found in the hut-circles of Dartmoor or in various cemeteries which undoubtedly belonged to the Bronze Age,2193 and I suggest that if the workmen who built Stonehenge had no use for bronze tools when they were building it, they were not more likely to lose them on the site than the masons who built St. Paul’s Cathedral to drop their table knives within the area of the churchyard. However, Professor Gowland does not pin his faith upon this argument. He points out2194 that many of the flint implements which he discovered at Stonehenge closely resemble those which were discovered by Canon Greenwell at Grime’s Graves, and which were attributed by him to the close of the Neolithic Age, or, at the latest, to a period when bronze had not come into general use.2195 But nobody who has learned the ABC of archaeology needs to be told that stone implements were used long after the introduction of bronze;2196 and no expert sees anything improbable in the theory that such tools were used in constructing Stonehenge towards the end of the Bronze Age. Besides, as Professor Gowland admits, Dr. Maskelyne has pointed out that ‘bronze tools would not work sarsens’;2197 assuming, then, that Stonehenge was erected in the Bronze Age, how could the sarsens have been dressed except with implements of stone? But the discovery upon which Professor Gowland lays the most stress is that of the deer-horn pick. Similar picks were found in large numbers at Grime’s Graves. The one which Professor Gowland found, if it really was a pick, must have been used for excavating the pits in which the stones of Stonehenge were erected; and Professor Gowland argues that if bronze tools had been in use at the time, ‘it would seem not unreasonable to assume that they would have been employed, as they would have been so much more effective for such work than the picks of deer’s horn.’2198 But no bronze pick has ever been found in this country; and deer-horn picks have been found in interments of the Bronze Age,2199 and even in a Romano-British deposit in the village of Woodyates on Cranborne Chase.2200 Professor Gowland provisionally assigns the date ‘about 2000-1800 B.C.’ for the erection of Stonehenge; and he adds that Sir Norman Lockyer’s astronomical calculation ‘gives an approximate date ... of 1680 B.C., with a margin of error ± 200 years’.

More than one attempt has been made to determine the date of Stonehenge from the orientation of its axis; and these attempts have been founded upon the assumption that one, at all events, of the objects which the builders had in view was the worship of the sun. ‘The chief evidence,’ as Sir Norman Lockyer and the late Mr. F. C. Penrose have observed, ‘lies in the fact that an “avenue” ... formed by two ancient earthen banks, extends for a considerable distance from the structure, in the general direction of the sunrise at the summer solstice.’2201 On the avenue, 100 feet from the so-called Slaughter Stone, stands a large monolith, called the ‘Friar’s Heel’, or the ‘Heel Stone’. At one time it was generally assumed that on Midsummer Day, at the time when Stonehenge was built, an observer, standing on or behind the ‘Altar Stone’, could see the sun rising above the tip of the Heel Stone. At the present time, however, as Mr. Arthur Hinks points out, ‘the sun rises further south than it has done for the last ten thousand years’; and yet, from the point of view of an observer standing behind the Altar Stone, ‘it still rises north of the stone.’2202 In fact ‘it is some seven days before or after midsummer day when it rises directly over the stone’.2203 Moreover, as Professor Flinders Petrie2204 says, the ‘skew position’ of the Altar Stone would seem to show that it is not now in its original position. Accordingly Sir Norman Lockyer felt obliged to leave the Friar’s Heel out of his calculations, and to confine himself to attempting to determine the orientation of the avenue.2205 The method which he and his colleague adopted was to peg out as accurately as possible ‘the central line between the low and often mutilated banks’ of the avenue, and then to measure ‘the bearings of two sections of this line near the beginning and the end’.2206 ‘The resulting observations,’ he tells us, ‘gave for the axis of the avenue nearest the commencement an azimuth of 49° 38' 48, and for that of the more distant 49° 32' 54.’2207 But neither of these measurements was adopted by Sir Norman. He found, or thought that he found, that the mean between the two values which he had obtained, namely, 49° 35' 51, was ‘confirmed by the information, supplied by the Ordnance Survey, that from the centre of the temple [Stonehenge] the bearing of the principal bench mark on the ancient fortified hill, about eight miles distant, a well-known British encampment named ... Sidbury, is 49° 34' 18; and that the same line continued through Stonehenge to the south-west strikes another ancient fortification, namely, Grovely Castle, about six miles distant, and at practically the same azimuth, viz., 49° 35' 51. For the above reasons,’ he says, ‘49° 34' 18 has been adopted for the azimuth of the avenue.’2208 Having regard to the rate of change in the obliquity of the ecliptic,2209 he concluded that the date of the foundation of Stonehenge was 1680 B.C.; but he admits that this date ‘may possibly be in error by ±200 years’.2210

It would appear then that, if Sir Norman Lockyer’s calculations are well founded, Stonehenge was erected at some time between 1880 and 1480 B.C. Certainly the conclusion does not err on the side of excessive precision. But the foundation upon which the calculations rest has been shown by Mr. Hinks to be rotten. To begin with, the assumption that Sidbury Hill was connected with the erection of Stonehenge is absurd. Does Sir Norman Lockyer mean to suggest that the bench mark was prehistoric? ‘In our climate,’ says Mr. Hinks, ‘Sidbury is probably not visible from Stonehenge at sunrise once in twenty years.’2211 In point of fact it is never so visible: only the trees on the top of the hill are to be seen. Furthermore, as Mr. Hinks points out, Sir Norman Lockyer has assumed that ‘for [the temple of] Karnak the moment of sunset was when the sun’s centre had just reached the horizon; for Stonehenge sunrise was the moment when the first tip of the sun appeared above the hill. It was necessary to adopt these precise yet different phases for the two cases, because any other assumptions would have led to results obviously absurd.’2212 Finally, Sir Norman Lockyer is obliged to assume that the builders of Stonehenge could tell the exact day on which the midsummer solstice occurred. The utter improbability of this assumption must be apparent to any one who remembers that the astronomer who constructed the Julian calendar miscalculated the dates both of the summer and of the winter solstice.2213

Mr. E. J. Webb, whose brilliant article in the Edinburgh Review of October, 1894, demolished Sir Norman Lockyer’s theory as to the orientation of the Egyptian temples,2214 has written me a letter in which the futility of attempting to determine the date of Stonehenge by astronomical reasoning is explained with a clearness which leaves nothing to be desired. ‘As,’ he writes, ‘the sun in our latitudes does not rise at right angles to the horizon, but with a considerable slant, it follows that the place where his upper rim begins to appear is appreciably further towards the north than the place where his centre appears, and this again than the place where he is first seen fully risen,—that is, where his lower edge touches the horizon.’ Now I think myself that, even if we could credit the builders with complete accuracy, attempts to get the date of the building astronomically would be vain, because (1) we do not know the exact place (if such there was) at which the observer’s eye was supposed to be placed. (Flinders Petrie does to some extent get over this difficulty by supposing that the observer took up a position from which the point of the Heel Stone appears exactly level with the horizon. I doubt, however, whether we have a right to be sure that the point is exactly where it was at first. Some of the stones have leaned over considerably, and why not this? But the difficulty is much greater for Lockyer, who takes no account of the Heel Stone.) (2) We do not know whether the ancients would have understood by the moment of sunrise the moment when the sun’s upper rim appears (A), or the moment when his centre appears (B), or the moment when his lower rim appears (C). (3) Even if we did know this, yet, as every one who has watched the sun rise must admit, it is practically quite impossible to be certain when any one of these moments occurs. Lockyer tacitly admits this when he arbitrarily takes as the moment of first appearance the time when 2' (about ¹/₁₆) of the sun’s disc are risen.

‘It is clear that (A being assumed) when Stonehenge was built, an observer looking along Flinders Petrie’s line of sight would see the Friar’s Heel considerably to the south of the place of sunrise, inasmuch as, though that place has ever since been moving southwards, we see it slightly to the south even now. Lockyer therefore puts the Friar’s Heel out of his theory altogether, in the belief that a stone which did not exactly mark the place of the most northerly sunrise could be of no use. I think, on the other hand, that a stone placed a little too far south would probably suit what is likely to have been the purpose in view even better than one which exactly marked the solstitial sunrise. For if, instead of asserting that Stonehenge was roofed over, and a beam of light admitted at the moment of sunrise to its darkened sanctuary2215—all of which is pure guesswork—we suppose that the builders were contemplating merely such bonfires and rejoicings as, by Lockyer’s own admission, certainly have taken place in various parts of the world, may we not ask how people in those ancient days knew when these festivities were to be held. For the later days, of which we have knowledge, the answer is easy enough: then people had the Julian calendar, according to which St. John’s Day, or whatever day was selected, always recurred at the same place in the solar year, whether at, or before, or after the solstice. But we do not know whether in pre-Roman times the inhabitants of Wiltshire had any settled calendar at all; and if they had, it is probable that, as in almost all ancient calendars, the days of the month, and therefore most likely the festivals, were reckoned by the moon.2216 The fifteenth, let us say, of a particular month meant the day when a particular moon was fifteen days old; and if this day should coincide in one year with the solstice, it would not coincide with it the next year, and could not have coincided with it the year before. How then could people tell when the Midsummer festival ought to be held? I answer that they might have very easily done so some time beforehand by the aid of a stone set up so as to mark, not the solstitial sunrise itself, but an earlier—and therefore of course also a later—one. If the Friar’s Heel stood, as on Lockyer’s theory it did, some little way to the south of the place of the midsummer sunrise, then the sun must have risen over it twice—first towards the end of his journey north, just before the solstice, and secondly on his return southward, just after the solstice. Now if the Stonehenge people looked out for the morning on which the sun first seemed to rise over the stone, and counted the days to a morning when he seemed to rise there again on his return journey, they could, by halving this number, obtain the time of the solstice with as much accuracy as they could have required. After doing this once, they could in following years always know, by watching the sun’s first approach to the Friar’s Heel, for what day to appoint the midsummer rejoicings. That these rejoicings took place at sunrise I do not assert. Bonfires, at least in these times, usually take place at night.... I do not think we have any right to say with certainty that any solstitial festival ever took place at Stonehenge or near it. For even granting that, as seems not unlikely, Stonehenge was orientated more or less closely to the solstitial sunrise, and that the Friar’s Heel was really used for the observation of the sun, it does not follow that Stonehenge was a “solar temple” any more than Milan Cathedral, which is orientated more or less closely to the equinoctial sunset, and has had a meridian line traced upon its pavement. And even if we knew that it was a solar temple, we should have no right to infer what kind of worship went on there.’2217

Although Dr. Evans’s arguments are not all equally strong, there can be little doubt that his view as to the date of the erection of Stonehenge is approximately correct. The stones were certainly not standing when round barrows were first erected on Salisbury Plain; for one is contained within the vallum, which, moreover, encroaches upon another.2218 Mr. F. R. Coles has shown that ‘so far as direct evidence has been obtained by rightly conducted excavations, the outstanding feature of all the Scottish circles that have been investigated is the presence within them of interments of the Bronze Age’.2219 That Stonehenge was erected before the close of this period, or at all events before the dawn of the Iron Age in Wiltshire, is certain; and, as it was the most elaborate and highly finished of all the stone circles of Great Britain, we may fairly infer that it was one of the latest of them all.

II. The most interesting pages of Dr. Evans’s article are those in which he attempts to trace the pedigree, so to speak, of Stonehenge, and to divine the purpose of its builders. He cites instances to show that ‘wherever the meaning of these great stone monuments has been clearly revealed to us, we find them connected either directly or indirectly with sepulchral usage’.2220 He contends that in the most characteristic examples ‘the Circle is an enlarged version of the ring of stones placed round the grave-mound; the Dolmen represents the cist within it; the Avenue is merely the continuation of the underground gallery, which in our earliest barrows leads to the sepulchral chamber’.2221 But is there any evidence that interments ever did take place within the precincts of Stonehenge? General Pitt-Rivers remarked that the question could be definitely settled by excavation;2222 but scientific excavation, as we have seen, has hitherto been confined within a small area. The evidence amounts to this:—a vessel, which Dr. Evans calls an incense-cup, was discovered by Inigo Jones,2223 and incense-cups have never been found except in association with interments;2224 while the numerous bones of domestic animals which have been exhumed, along with charcoal and fragments of pottery, from the interior circle,2225 point to the conclusion that Stonehenge was the scene of sepulchral rites such as we know to have been performed in barrows.2226 Furthermore, the older monument of Avebury contains two smaller stone circles, within each of which are the remains of a stone chamber, which, Dr. Evans argues, ‘there can be little doubt once contained interments.’2227 But Dr. Evans is at no great pains to argue that Stonehenge was itself a cemetery: it is on its connexion, close or distant, with sepulchral usage that he lays stress. While he points out that ‘in the case of the Chambered Barrows the [surrounding] stones may be said still to fulfil an original structural function’, he holds that ‘in the case of the Circles they bear a more purely ritual signification. In some cases,’ he adds, ‘we find transitional examples in which the stone circle is actually seen in the act as it were of separating itself from the earth barrows. Thus in the great monument of New Grange [in Ireland] the stone circle is separated by an interval of some twenty feet from the central mound.’ Then, going to the Far East for an illustration, he tells us that, while the stone circles and dolmens which are still erected by the Khasis of Assam ‘are in themselves non-sepulchral’, they ‘are reared as a propitiation either to the departed Spirits of their own ancestors or to any other Spirit’.2228 But Dr. Evans does not deny that Stonehenge was also a solar temple: he admits, indeed, that its orientation ‘certainly seems to associate the Sun in the religion of the spot’.2229 This theory is supported by observations made by Professor Gowland in Japan. ‘There,’ he tells us, ‘on the seashore at Futa-mi-gaura ... the orientation of the shrine of adoration is given by two gigantic rocks which rise from the sea as natural pillars. The sun, as it rises over the mountains of the distant shore, is observed between them, and the customary prayers and adorations made ... the point from which the sun is revered is marked by a structure of the form of a trilithon,’2230 &c.

But although some evidence has been collected in support of the theory that certain stone circles in the British Isles and elsewhere were orientated more or less closely to the Midsummer sunrise, it does not necessarily follow that they were solar temples;2231 and a scientifically conducted examination of the circles of Kincardineshire and Aberdeenshire has shown that their main diameters ‘are in scarcely any instance oriented (sic) to any point of the compass as we understand the term’;2232 while Mr. W. C. Lukis, pointing out that on Dartmoor and in Cornwall circles are to be found in clusters, and that there are three circles quite close to one another at Stanton Drew, asks, ‘if they were temples, why should the worshippers have been gathered into separate congregations?’2233 The only answer which I can suggest is that while each of these circles was probably erected either for sepulchral purposes or in honour of a dead ancestor, the rites which were from time to time solemnized within them may have been connected with the worship of the sun. There is no reason to believe that in any megalithic circle in the British Isles solar worship was more than incidental.

About forty years ago the late distinguished archaeologist, Professor Nilsson, wrote an article,2234 the main object of which was to prove that Stonehenge was a temple of Phoenician origin, consecrated to the worship of Baal; but the evidence upon which he relied was so unsubstantial that no useful purpose would be served by summarizing his arguments, which, indeed, are virtually obsolete.

Professor Flinders Petrie2235 argues that certain parts of Stonehenge are much later than others; and Dr. Evans, who agrees with him, remarks that ‘this is strongly shown by the fact that each of the Stone Circles as well as the Earth Circle has a different centre’.2236 Dr. Evans also points out that, in the case of the circles which are still erected in the East, ‘the huge blocks are not all put up at one time but in batches of an equal number of stones at intervals of time.’

Professor Gowland has shown that the sarsen stones in the outer circle must have been erected before the trilithons, and the trilithons before the blue-stones.2237 ‘That the stones,’ he remarks, ‘of the central trilithon were erected from the inside of the circle has been conclusively demonstrated by the excavations; hence the “blue-stones” in front cannot have been erected before them. Moreover, the “bluestone”, No. 68, the base of which was laid bare in Excavation V, was found to be set in the rubble which had been used to fill up the foundation of No. 56, and further, in a lower layer than its base, there were two ... blocks of sarsen with tooled surfaces.... If [the outer sarsens were set up] from the inside [of the circle], their erection must have preceded that of the trilithons and hence of the “bluestones”. On the other hand, should the outer sarsens have been reared from the outside, it would not be possible for the “bluestones” to have been placed in position before them, as they would then have seriously interfered with, if not altogether prevented the erecting operations.’ Mr. William Cunnington, however, observes that ‘the fact that specimens of all the varieties of rocks which constitute the inner circle of Stonehenge have been found in the mixed substance at the base of ... [the stump of one of the blue-stones] proves that they were all on the spot when the inner ellipse was erected’;2238 and Professor Gowland, who confirms this view, concludes that ‘no long interval of time separated the erection of the sarsen and the “bluestone” monoliths, although the work must have occupied a considerable period’.

III. Unwarned by the Edinburgh Review and Mr. Hinks, Sir Norman Lockyer published in Nature2239 a series of ‘Notes on Stonehenge’, which might be safely ignored if his authority had not made converts, even among archaeologists and men of science who happen to be ignorant of certain essential facts. He now maintains that the sarsens ‘and above all the trilithons of the magnificent naos represent a re-dedication and a re-construction of a much older temple’; and, further, that ‘the older temple dealt, primarily but not exclusively, with the May year’, while ‘the newer temple represented a change of cult, and was dedicated primarily to the solstitial year’. It is unnecessary to examine in detail the process by which he has endeavoured to establish these conclusions; but I shall give a few specimens of his work.

‘Acting,’ says Sir Norman, ‘on a very old tradition, the people from Salisbury and other surrounding places go to observe the sunrise on the longest day of the year at Stonehenge. We therefore,’ he concludes, ‘are perfectly justified in assuming that it was a solar temple.’2240 Not improbably it was—from one point of view; but how old is the tradition? The earliest extant mention of Stonehenge is in the Historia Anglorum2241 of Henry of Huntingdon, who lived in the twelfth century, but who does not refer to the tradition. Stonehenge, according to Sir Norman Lockyer, was rebuilt in 1680 B.C. It is therefore impossible to prove that the tradition originated even as early as two thousand nine hundred years after the alleged date of the alleged second dedication of Stonehenge. Tentatively I would suggest that it may have arisen after 1771, when the astronomical theory was anticipated by a Dr. John Smith.2242

Among the ‘considerations’ to which Sir Norman would ‘direct attention’ in support of his theory the fifth2243 runs as follows:—‘It is quite possible that the rebuilding of the temple in 1680 B.C. was part of a very large general plan which could only have been undertaken by a large, powerful and comparatively civilized tribe or people under strict government, commanding the services of skilled mathematicians, for Stonehenge, Old Sarum, and Grovely Castle occupy the points of an equilateral triangle of exactly six miles in the sides, and the three sides are continuations of the entrances at Stonehenge and Old Sarum and of a ditch running through the centre of Grovely Castle, and the line Stonehenge—Old Sarum passes exactly through Salisbury Spire, which again is exactly two miles from Sarum. We ought to restore the old name, Solisbury.’

‘Skilled mathematicians’ on Salisbury Plain in 1680 B.C., a thousand years before the dawn of mathematics in Greece,2244 busily engaged in forming, for some recondite religious purpose, gigantic equilateral triangles! Sir Norman italicized the word ‘exactly’. Evidently then he wished to impress upon us, in proof of the mathematicians’ skill, not only that they made their triangle equilateral, but that each side measured six miles,—no more and no less. Is it not a remarkable coincidence that the unit of measurement in the British Bronze Age was the English statute mile? I confess that I cannot grasp the significance of the prolongation of ‘the line Stonehenge—Old Sarum’ to Salisbury Spire, or of the fact that this additional section was ‘exactly two miles long’, unless the builders of Stonehenge were Christians as well as mathematicians and Salisbury Spire was standing in 1680 B.C. Nor indeed, it should seem, can Sir Norman himself: at all events in Stonehenge and other British Monuments Astronomically considered—a book which is, in the main, a reproduction of his ‘Notes’—the passage which I have quoted disappears: equilateral triangle and skilled mathematicians are left to the kindly obscurity of Nature. But if ‘the line Stonehenge—Old Sarum’ and the line Stonehenge—Grovely Castle have lost all significance, why persist in staking a hopeless case upon the imaginary importance of the line Stonehenge—Sidbury Hill?

Sir Norman Lockyer has not restricted his researches to Stonehenge, sun-worship, and the solstitial year. He has discovered instances in which stone circles have been used for the observation not of the sun but of the stars, and in which, ‘on account of the change in a star’s place due to precession,’ ‘the sight line has been changed in the Egyptian manner.’2245 Among these astral temples were ‘the three circles of the Hurlers, near Liskeard’ and ‘the circles at Stanton Drew’. After an interesting calculation he announces that ‘we have the following declinations approximately:—

Here then,’ he observes, ‘we have declinations to work on, but declinations of what star? Vega is ruled out as its declination is too high.’ He concludes that the star which ‘the astronomer-priests’ observed was Arcturus, and that ‘the approximate dates of the use of the three circles at the Hurlers’ are 1600 B.C. for the southern, 1500 for the central, and 1300 for the northern circle; and at Stanton Drew 1260 B.C. for the great circle and 1075 B.C. for the south-western circle.2246

Once more I am puzzled. Sir Norman remarks that all these circles are considerably older than Stonehenge.2247 Stonehenge, he says, was in use as a solar temple in 1680 B.C. and a good deal earlier: none of the older circles began to be used as an astral temple until 1600 B.C. Why? Surely not because Arcturus, Capella, and Vega all refuse to fit in with ‘the sight lines’ which Sir Norman has discovered except at inconveniently late dates? Again, ‘Vega is ruled out as its declination is too high.’ But the present declination of Vega happens to be exactly 38½°. ‘In other words,’ as Mr. Webb writes to me, ‘there exists between the circle and one of the brightest stars in the sky a perfect correspondence, which is nevertheless, beyond all possibility of doubt, wholly accidental.’ Why did Sir Norman omit to mention this significant fact?

But second thoughts or kind friends have once more come to Sir Norman’s rescue. In his book ‘Vega is ruled out as its declination was too high’2248 (the italics are mine). ‘He had become aware,’ remarks the lynx-eyed Mr. Webb, ‘of the damaging fact that the present declination of Vega actually is 38½° N., in other words that, on his own principles, we can prove that the Hurlers were set up to-day.’
