Chap. 109. (105.)—Of Naphtha.

Naphtha is a substance of a similar nature [The substance here mentioned may be considered as not differing essentially from the Maltha of the last chapter, except in being of a more fluid consistence.] (it is so called about Babylon, and in the territory of the Astaceni, in Parthia [The Astaceni are supposed to have inhabited a district near the sources of the Indus, probably corresponding to the modern Cabul.]), flowing like liquid bitumen. It has a great affinity to fire, which instantly darts on it wherever it is seen [We may conceive of a quantity of inflammable vapour on the surface of the naphtha, which might, in some degree, produce the effect here described.]. It is said, that in this way it was that Medea burned Jason’s mistress; her crown having taken fire, when she approached the altar for the purpose of sacrificing [Horace, in one of his Epodes, where he refers to the magical arts of Medea, says, that it was a cloak, “palla,” which was sent to Creüsa; v. 65. So far as there is any foundation for the story, we may suppose that some part of her dress had been impregnated with an inflammable substance, which took fire when she approached the blazing altar.].

Chap. 110. (106.)—Places Which Are Always Burning.

Among the wonders of mountains there is Ætna, which always burns in the night [When the volcanos are less active the flame is visible in the night only.], and for so long a period has always had materials for combustion, being in the winter buried in snow, and having the ashes which it has ejected covered with frost. Nor is it in this mountain alone that nature rages, threatening to consume the earth [The observations of modern travellers and geologists have proved, that the number of extinct volcanos is considerably greater than those now in action.]; in Phaselis, the mountain Chimæra burns, and indeed with a continual flame, day and night [Chimæra was a volcano in Lycia, not far from the Xanthus; the circumstance of its summit emitting flame, while its sides were the resort of various savage animals, probably gave rise to the fabulous story of the Centaur of this name, a ferocious monster who was continually vomiting forth flame.]. Ctesias of Cnidos informs us, that this fire is kindled by water, while it is extinguished by earth and by hay [The word in the text is “fœnum”; Hardouin suggests that the meaning of the author may have been litter, or the refuse of stables. Lemaire, i. 454.]. In the same country of Lycia, the mountains of Hephæstius, when touched with a flaming torch [The emission of a gas, which may be kindled by the application of flame, is a phænomenon of no very rare occurrence; but the effects are, no doubt, much exaggerated. See the remarks of Alexandre in Lemaire, i. 454.], burn so violently, that even the stones in the river and the sand burn, while actually in the water: this fire is also increased by rain. If a person makes furrows in the ground with a stick which has been kindled at this fire, it is said that a stream of flame will follow it. The summit of Cophantus, in Bactria [The country of the Bactrians was a district to the S.E. of the Caspian Sea, and to the north of the sources of the Indus, nearly corresponding to the modern Bucharia.], burns during the night; and this is the case in Media and at Sittacene [There would appear to be some uncertainty as to the locality of this place: our author derived his statement from the writer of the treatise de Mirab. Auscult.], on the borders of Persia; likewise in Susa, at the White Tower, from fifteen apertures [“Caminis.”], the greatest of which also burns in the daytime. The plain of Babylon throws up flame from a place like a fish-pond [Probably the crater of a former volcano.], an acre in extent. Near Hesperium, a mountain of the Æthiopians [This mountain, as well as the Θεῶν ὄχημα mentioned below, has been supposed to be situated on the west of Africa, near Sierra Leone, or Cape Verd; but, as I conceive, without sufficient authority. See Alexandre in Lemaire, i. 455.], the fields shine in the night-time like stars; the same thing takes place in the territory of the Megalopolitani. This fire, however, is internal [“Internus.” “In interiore nemore abditus.” Hardouin in Lemaire, i. 455.], mild, and not burning the foliage of a dense wood which is over it [If this account be not altogether fabulous, the appearance here described may be, perhaps, referred to the combustion of an inflammable gas which does not acquire a very high temperature.]. There is also the crater of Nymphæum [We have an account of this place in Strabo, vii. 310. Our author has already referred to it in the 96th chapter of this book, as a pool or lake, containing floating islands; and he again speaks of it in the next chapter.], which is always burning, in the neighbourhood of a cold fountain, and which, according to Theopompus, presages direful calamities to the inhabitants of Apollonia [We have an account of this volcano in Ælian, Var. Hist. xiii. 16. It would appear, however, that it had ceased to emit flame previous to the calamitous events of which it was supposed to be the harbinger.]. It is increased by rain [This circumstance is mentioned by Dion Cassius, xli. 174. We may conceive that a sudden influx of water might force up an unusually large quantity of the bitumen.], and it throws out bitumen, which, becoming mixed with the fountain, renders it unfit to be tasted; it is, at other times, the weakest of all the bitumens. But what are these compared to other wonders? Hiera, one of the Æolian isles, in the middle of the sea, near Italy, together with the sea itself, during the Social war, burned for several days [We have a full account of this circumstance in Strabo, vi. 277.], until expiation was made, by a deputation from the senate. There is a hill in Æthiopia called Θεῶν ὄχημα [“Currum deorum Latine licet interpretari.” Hardouin in Lemaire, i. 456.], which burns with the greatest violence, throwing out flame that consumes everything, like the sun [“torrentesque solis ardoribus flammas egerit;” perhaps the author may mean, that the fires of the volcano assist those of the sun in parching the surface of the ground.]. In so many places, and with so many fires, does nature burn the earth!

Chap. 111. (107.)—Wonders of Fire Alone.

But since this one element is of so prolific a nature as to produce itself, and to increase from the smallest spark, what must we suppose will be the effect of all those funeral piles of the earth [“Tot rogis terræ?” in reference to the remark in a former chapter, “natura terras cremat.”]? What must be the nature of that thing, which, in all parts of the world, supplies this most greedy voracity without destroying itself? To these fires must be added those innumerable stars and the great sun itself. There are also the fires made by men [“Humani ignes,” according to Hardouin, “Hi nostri ignes, quos vitæ usus requirit, ut Tullius ait de Nat. Deor. ii. 67;” Lemaire, i. 457.], those which are innate in certain kinds of stones, those produced by the friction of wood [This is the mode which many savage tribes employ for exciting flame.], and those in the clouds, which give rise to lightning. It really exceeds all other wonders, that one single day should pass in which everything is not consumed, especially when we reflect, that concave mirrors placed opposite to the sun’s rays produce flame more readily than any other kind of fire; and that numerous small but natural fires abound everywhere. In Nymphæum there issues from a rock a fire which is kindled by rain; it also issues from the waters of the Scantia [It is not known whether the Scantia was a river or a lake, or where it was situated; see Alexandre in Lemaire, i. 457.]. This indeed is a feeble flame, since it passes off, remaining only a short time on any body to which it is applied: an ash tree, which overshadows this fiery spring, remains always green [This may have been owing to the emission of an inflammable gas which burns at a comparatively low temperature, as was observed on a former occasion.]. In the territory of Mutina fire issues from the ground on the days that are consecrated to Vulcan [These are said by Columella, xi. 3, to occur in August; the statement as to the fire occurring on these particular days we may presume is erroneous.]. It is stated by some authors, that if a burning body falls on the fields below Aricia [Aricia was a town in Campania, near the modern Lake of Nemi: this place, as well as the other places mentioned by our author, were probably of volcanic origin.], the ground is set on fire; and that the stones in the territory of the Sabines and of the Sidicini [Sidicinum was a town in Campania, also called Teanum; probably the modern Teano.], if they be oiled, burn with flame. In Egnatia [Egnatia was a town in Calabria, on the coast of the Adriatic: the circumstance mentioned by our author is ridiculed by Horace, in his well-known lines, Sat. i. 5, 97; but it is not improbable that there may be some foundation for it.], a town of Salentinum, there is a sacred stone, upon which, when wood is placed, flame immediately bursts forth. In the altar of Juno Lacinia [This circumstance is referred to by Val. Maximus, i. 8, 18. The altar was probably in the neighbourhood of the Lacinian Promontory, at the S.W. extremity of the Bay of Tarentum, the modern Capo delle Colonne.], which is in the open air, the ashes remain unmoved, although the winds may be blowing from all quarters.

It appears also that there are sudden fires both in waters and even in the human body; that the whole of Lake Thrasymenus was on fire [This may be referred to the inflammable vapours mentioned above, unless we regard the whole narrative as fabulous.]; that when Servius Tullius, while a child, was sleeping, flame darted out from his head [See Livy, i. 39, and Val. Maximus, i. 6. 2. Although it would be rash to pronounce this occurrence and the following anecdotes respecting Marcius to be absolutely impossible, we must regard them as highly improbable, and resting upon very insufficient evidence.]; and Valerius Antias informs us, that the same flame appeared about L. Marcius, when he was pronouncing the funeral oration over the Scipios, who were killed in Spain; and exhorting the soldiers to avenge their death. I shall presently mention more facts of this nature, and in a more distinct manner; in this place these wonders are mixed up with other subjects. But my mind, having carried me beyond the mere interpretation of nature, is anxious to lead, as it were by the hand, the thoughts of my readers over the whole globe.

Chap. 112. (108.)—The Dimensions of the Earth.

Our part of the earth, of which I propose to give an account, floating as it were in the ocean which surrounds it (as I have mentioned above [In the of this book.]), stretches out to the greatest extent from east to west, viz. from India to the Pillars consecrated to Hercules at Gades, being a distance of 8568 miles [In the estimate of distances I have given the numbers as they occur in the text of Lemaire, although, in many cases, there is considerable doubt as to their accuracy. See the observations of Hardouin and Alexandre in Lemaire, i. 460.], according to the statement of Artemidorus [Artemidorus was an Ephesian, who wrote on geography; see Hardouin’s Index Auct., Lemaire, i. 167.], or according to that of Isidorus [Isidorus was a native of Nicæa; he appears to have been a writer on various topics in natural history, but not much estimated; see Hardouin’s Index Auct., in Lemaire, i. 194.], 9818 miles. Artemidorus adds to this 491 miles, from Gades, going round by the Sacred Promontory, to the promontory of Artabrum [The modern Cape St. Vincent and Cape Finisterre.], which is the most projecting part of Spain.

This measurement may be taken in two directions. From the Ganges, at its mouth, where it discharges itself into the Eastern ocean, passing through India and Parthyene, to Myriandrus [This was a city on the Sinus Issicus, the present Gulf of Aiasso, situated, according to Brotier, between the sites of the modern towns of Scanderoon and Rosos. See Lemaire, i. 461.], a city of Syria, in the bay of Issus, is a distance of 5215 miles [Respecting this and the other distances mentioned in this chapter, I may refer the reader to the remarks of Hardouin in Lemaire, i. 461.]. Thence, going directly by sea, by the island of Cyprus, Patara in Lycia, Rhodes, and Astypalæa, islands in the Carpathian sea, by Tænarum in Laconia, Lilybæum in Sicily and Calaris in Sardinia, is 2103 miles. Thence to Glades is 1250 miles, making the whole distance from the Eastern ocean 8568 miles [It is scarcely necessary to remark, that the calculations of our author do not indicate the real distance between the extreme points of the habitable parts of the globe, as known to the ancients, but the number of miles which must be passed over by a traveller, in going from place to place; in the first instance, a considerable part of the way by sea, and, in the second, almost entirely by land.].

The other way, which is more certain, is chiefly by land. From the Ganges to the Euphrates is 5169 miles; thence to Mazaca, a town in Cappadocia, is 319 miles; thence, through Phrygia and Caria, to Ephesus is 415 miles; from Ephesus, across the Ægean sea to Delos, is 200 miles; to the Isthmus is 212 1 / 2 miles; thence, first by land and afterwards by the sea of Lechæum and the gulf of Corinth, to Patræ in Peloponnesus, 90 miles; to the promontory of Leucate 87 1 / 2 miles; as much more to Corcyra; to the Acroceraunian mountains 132 1 / 2, to Brundisium 87 1 / 2, and to Rome 360 miles. To the Alps, at the village of Scingomagum [It appears to be difficult to ascertain the identity of the place here mentioned; I may refer to the remarks of Hardouin and Brotier in Lemaire, i. 464.], is 519 miles; through Gaul to Illiberis at the Pyrenees, 927; to the ocean and the coast of Spain, 331 miles; across the passage of Gades 7 1 / 2 miles; which distances, according to the estimate of Artemidorus, make altogether 8945 miles.

The breadth of the earth, from south to north, is commonly supposed to be about one-half only of its length, viz. 4490 miles; hence it is evident how much the heat has stolen from it on one side and the cold on the other: for I do not suppose that the land is actually wanting, or that the earth has not the form of a globe; but that, on each side, the uninhabitable parts have not been discovered. This measure then extends from the coast of the Æthiopian ocean, the most distant part which is habitable, to Meroë, 1000 miles [The same remarks may be made upon this and the following numbers as upon those in the former paragraph; for further information I shall refer my readers to the notes of Hardouin, Brotier, and Alexandre, in Lemaire, i. 465-468.]; thence to Alexandria 1250; to Rhodes 562; to Cnidos 87 1 / 2; to Cos 25; to Samos 100; to Chios 94; to Mitylene 65; to Tenedos 44; to the promontory of Sigæum 12 1 / 2; to the entrance of the Euxine 312 1 / 2; to the promontory of Carambis 350; to the entrance of the Palus Mæotis 312 1 / 2; and to the mouth of the Tanais 275 miles, which distance, if we went by sea, might be shortened 89 miles. Beyond the Tanais the most diligent authors have not been able to obtain any accurate measurement. Artemidorus supposes that everything beyond is undiscovered, since he confesses that, about the Tanais, the tribes of the Sarmatæ dwell, who extend towards the north pole. Isidorus adds 1250 miles, as the distance to Thule [There is great uncertainty respecting the locality of the Thule of the ancients; there was, in fact, nothing known respecting the locality or identity of any of the places approaching to the Arctic circle; the name appears to have been vaguely applied to some country lying to the north of the habitable parts of Europe. In note, p. 109, I have already had occasion to offer some remarks on the locality of Thule. Our author speaks of Thule in two subsequent parts of his work, iv. 30 and vi. 39.]; but this is mere conjecture. For my part, I believe that the boundaries of Sarmatia really extend to as great a distance as that mentioned above: for if it were not very extensive, how could it contain the innumerable tribes that are always changing their residence? And indeed I consider the uninhabitable portion of the world to be still greater; for it is well known that there are innumerable islands lying off the coast of Germany [It is probable, that these supposed “immense islands,” if they were not entirely imaginary, were the countries of Sweden and Norway, the southern extremities alone of which had been visited by the ancients.], which have been only lately discovered.

The above is all that I consider worth relating about the length and the breadth of the earth [Strabo, ii.; Vitruvius, i. 6; Macrobius, in Somn. Scip. ii. 20.]. But Eratosthenes [Our author has previously referred to Eratosthenes, in the 76th chapter of this book.], a man who was peculiarly well skilled in all the more subtle parts of learning, and in this above everything else, and a person whom I perceive to be approved by every one, has stated the whole of this circuit to be 252,000 stadia, which, according to the Roman estimate, makes 31,500 miles. The attempt is presumptuous, but it is supported by such subtle arguments that we cannot refuse our assent. Hipparchus [Our author has referred to Hipparchus, in the 9th chapter of this book.], whom we must admire, both for the ability with which he controverts Eratosthenes, as well as for his diligence in everything else, has added to the above number not much less than 25,000 stadia.

(109.) Dionysodorus is certainly less worthy of confidence [“Aliter, inquit, et cautius multo Dionysodorus est audiendus, qui miraculo solo nititur, quam Hipparchus et Eratosthenes, qui geometricis nituntur principiis.” Hardouin in Lemaire, i. 469. Nothing further is known of Dionysodorus; see Hardouin’s Index Auct. in Lemaire, i. 123.]; but I cannot omit this most remarkable instance of Grecian vanity. He was a native of Melos, and was celebrated for his knowledge of geometry; he died of old age in his native country. His female relations, who inherited his property, attended his funeral, and when they had for several successive days performed the usual rites, they are said to have found in his tomb an epistle written in his own name to those left above; it stated that he had descended from his tomb to the lowest part of the earth, and that it was a distance of 42,000 stadia. There were not wanting certain geometricians, who interpreted this epistle as if it had been sent from the middle of the globe, the point which is at the greatest distance from the surface, and which must necessarily be the centre of the sphere. Hence the estimate has been made that it is 252,000 stadia in circumference.

Chap. 113.—The Harmonical Proportion of the Universe.

That harmonical proportion, which compels nature to be always consistent with itself, obliges us to add to the above measure, 12,000 stadia; and this makes the earth one ninety-sixth part of the whole universe.
