The account which Agatharcides gives of Sabæa is very curious and important; and, as we shall afterwards have occasion to make use of it, in endeavouring to prove that, in very early ages, the Arabians supplied the western world with the productions of the east, we shall extract here what he says of Sabæa from the translation of Dr. Vincent.
"Sabæa, (says Agatharcides,) abounds with every production to make life happy in the extreme: its very air is so perfumed with odours, that the natives are obliged to mitigate the fragrance by scents that have an opposite tendency, as if nature could not support even pleasure in the extreme. Myrrh, frankincense, balsam, cinnamon, and casia are here produced, from trees of extraordinary magnitude. The king, as he is, on the one hand, entitled to supreme honour, on the other, is obliged to submit to confinement in his palace; but the people are robust, warlike, and able mariners: they sail in very large vessels to the country where the odoriferous commodities are produced; they plant colonies there, and import from thence the larimna, an odour no where else to be found. In fact, there is no nation on the earth so wealthy as the Gerrheans and Sabeans, as being in the centre of all the commerce that passes between Asia and Europe. These are the nations which have enriched the kingdom of Ptolemy: these are the nations that furnish the most profitable agencies to the industry of the Phoenicians, and a variety of advantages which are incalculable. They possess themselves every profusion of luxury, in articles of plate and sculpture, in furniture of beds, tripods, and other household embellishments, far superior in degree to any thing that is seen in Europe: their expence of living rivals the magnificence of princes: their houses are decorated with pillars glistening with gold and silver: their doors are crowned with vases and beset with jewels: the interior of their houses corresponds with the beauty of their outward appearance, and all the riches of other countries are here exhibited in a variety of profusion. Such a nation, and so abounding in superfluity, owes its independence to its distance from Europe; for their luxurious manners would soon render them a prey to the European sovereigns, who have always troops on foot prepared for any conquest; and who, if they could find the means of invasion, would soon reduce the Sabeans to the condition of their agents and factors; whereas they are now obliged to deal with them as principals."
The importance and the bearing of these curious facts, first brought to our notice by Agatharcides, as well as the inferences which may be drawn from them regarding the mode in which the ancients obtained their commodities of India, will call our particular attention afterwards: at present we shall merely notice the characteristic and minute picture which Agatharcides has drawn of the Sabeans, and the just notions he had formed on the nature of a commerce, of which all the other writers of antiquity seemed to have been utterly ignorant.
Beyond Sabæa to the east, Agatharcides possessed no information, though, like all the ancients, he is desirous of supplying his want of it by indulging in the marvellous: it is, however, rather curious that, among other particulars, undoubtedly unfounded, such as placing the Fortunate islands off the coast beyond Sabæa, and his describing the flocks and herds as all white, and the females as polled;--he describes that whiteness of the sea, to which we have already alluded, as confirmed by modern travellers. From these unfounded particulars, our author soon emerges again into the truth; for he describes the appearance of the different constellations, and especially notices that to the south of Sabæa there is no twilight in the morning; but when he adds, that the sun, at rising, appears like a column--that it casts no shadow till it has been risen an hour, and that the evening twilight lasts three hours after it has set; it is obvious that the information of that age (of which we may justly suppose the library of Alexandria was the great depository) did not extend beyond Sabæa.
That Agatharcides had access to and made ample use of the journal of Nearchus (of which we have given such a complete abstract), is evident from various parts of his work; but it is also evident, by comparing his description of those countries and their inhabitants, which had been visited and described by Nearchus, that he had access to other sources of intelligence, by means of which he added to the materials supplied by the latter.
It will be recollected that Nearchus describes in a particular manner, the Icthyophagi of Gadrosia: Agatharcides also describes Icthyophagi, though it is not clear whether he means to confine his description to those of Gadrosia, or to extend it to others on the coast of Arabia and Africa. The mode practised by the Icthyophagi, according to him, is exactly that which was practised by them in catching fish, according to Nearchus: he also coincides with that author in various other particulars respecting the use of the bones of whales, or other large fish, in the construction of their houses; their ignorance and barbarism, their dress and mode of life. All this he probably borrowed from Nearchus; but he adds one circumstance which indubitably proves, that the knowledge of the eastern part of the world had considerably advanced since the era of Alexander: he expressly states, that beyond the straits that separate Arabia from the opposite coast, there are an immense number of islands, scattered, very small, and scarcely raised above the surface of the ocean. If we may advert to the situation assigned to these islands, on the supposition that the straits which separate Arabia from the opposite coast, mean the entrance to the Gulph of Persia, we shall not be able to ascertain what these islands are; but if in addition to the circumstances of their being scattered, very small, and very low, we add what Agatharcides also notices, that the natives have no other means of supporting life but by the turtles which are found near them in immense numbers, and of a very large size, we shall be disposed, with Dr. Vincent, to consider these as the Maldive Islands. It may be objected to this supposition, that the Maldives are situated at a very great distance from the straits that separate Arabia from the opposite coast; but a cursory acquaintance with the geographical descriptions of the ancients will convince us, that their information respecting the situation of countries was frequently vague and erroneous, (as indeed it must have been, considering the imperfect means they possessed of measuring or even judging of distances, especially by sea) while, at the same time, their information respecting the nature of the country, the productions of its soil, and the manners, &c. of its inhabitants, was surprisingly full and accurate. In identifying places mentioned by the ancients, we should therefore be guided more by the descriptions they give, than by the locality they assign to them. Agatharcides, it is true, adds that these islands extend along the sea, which washes Gadrosia and India; but he probably had very confused notions of the extent and form of India; and, at any rate, giving the widest latitude to the term, the same sea may be said to wash Gadrosia and the Maldive Islands. If these are the islands actually meant by Agatharcides, it is the earliest notice of them extant.
Our concern with Agatharcides relates only to the geographical knowledge which his writings display; and even of that we can only select such parts as are most important, and at the same time point out and prove the advances of geographical knowledge, and of commercial enterprize; before, however, we leave him, we may add one fact, not immediately relating to our peculiar subject, which he records: after stating that the soil of Arabia was, as it were, impregnated with gold, and that lumps of pure gold were found there from the size of an olive to that of a nut, he adds, that iron was twice, and silver ten times, the value of gold. If he is accurate in the proportionate values which he respectively assigns to these metals, it proves the very great abundance of gold; since, in most of the nations of antiquity, the values of gold and silver were the reverse of what they were in Arabia, gold being ten times the value of silver. The comparative high value of iron to gold is still more extraordinary, and seems to indicate not only a great abundance of the latter metal, but also a great scarcity of the former, or a very great demand for it in consequence of the extended and improved state of those arts and manufactures in which iron is an essential requisite, and which indicate an advanced degree of knowledge and civilization. We are not aware of a similar fact, with respect to the proportionate value of iron and silver, being recorded of any other nation of antiquity. It is not to be supposed, however, that the cheapness of gold, measured by iron and silver, could long continue in Arabia, unless we believe that their intercourse with other nations was very limited; because a regular and extensive intercourse would soon assimilate, in a great degree at least, the value of gold measured by iron and silver, as it existed in Arabia, to its value, as measured by the same metals in those countries with which Arabia traded.
But to return from this slight digression;--Artemidorus has been already mentioned as a geographer subsequent to Agatharcides, who copied Agatharcides, and from whom Diodorus Siculus and Strabo in their turns copied. There were two ancient writers of this name born at Ephesus; the one to whom we have alluded, is supposed to have lived in the reign of Ptolemy Lathyrus, A.C. 169; by others he is brought down to A.C. 104. Little is known respecting him; nor does he seem to have added much to geographical science or knowledge: he is said by Pliny to have first applied the terms of length and breadth, or latitude and longitude. By comparing those parts of Diodorus Siculus and Strabo, which they avowedly copy from him, with the track of Agatharcides: in the Red Sea, we are enabled to discover only a few additions of importance to the geographical knowledge supplied by the former: Agatharcides, it will be remembered, brings his account of the African side of the Red Sea no lower down than Ptolemais: he does not even mention the expedition of Ptolemy Euergetes to Aduli; nor the passage of the straits, though Eratosthenes, as cited by Strabo, proves that it was open in his time. In the time of Artemidorus, however, the trade of Egypt on the coast of Africa had reached as low down as the Southern Horn; that this trade was still in its infancy, is apparent from a circumstance mentioned by Strabo, on the authority of Artemidorus; that at the straits the cargo was transferred from ships to boats; bastard cinnamon, perhaps casia lignea or hard cinnamon, is specified as one of the principal articles which the Egyptians obtained from the coast of Africa, when they passed the straits of Babelmandeb.
The next person belonging to the Alexandrian school, to whom the sciences on which geography rest, as well as geography itself, is greatly indebted, was Hipparchus. Scarcely any particulars are known respecting him: even the exact period in which he flourished, is not accurately fixed; some placing him 159 years, others 149, and others again bringing him down to 129 years before Christ. He was a native of Nice in Bithynia, but spent the greater part of his life at the court of one of the Ptolemies. It is supposed that he quitted his native place in consequence of some ill treatment which he had received from his fellow citizens: at least we are informed by Aurelius Victor, that the emperor Marcus Aurelius obliged the inhabitants of Nice to send yearly to Rome a certain quantity of corn, for having beaten one of their citizens, by name Hipparchus, a man of great learning and extraordinary accomplishments. They continued to pay this tribute to the time of Constantine, by whom it was remitted. As history does not inform us of any other person of note of this name, a native of Nice in Bithynia, it is highly probable that this was the Hipparchus, the astronomer and geographer. That it was not unusual for conquerors and sovereigns to reward or punish the descendants of those who had behaved well or ill to celebrated men who had flourished long previously, must be well known to those conversant with ancient history. The respect paid to the memory of Pindar, by the Spartans, and by Alexander the Great, when they conquered Thebes, is a striking instance of the truth of this observation.
Hipparchus possessed the true spirit of philosophy: having resolved to devote himself to the study of astronomy, his first general [principal->principle] was to take nothing for granted; but setting aside all that had been taught by former astronomers, to begin anew, and examine and judge for himself: he determined not to admit any results but such as were grounded either in observations and experiments entirely new, made by himself or on a new examination of former observations, conducted with the utmost care and caution. In short, he may justly be regarded as one of the first philosophers of antiquity who had a slight glimpse of the grand maxim, which afterwards immortalized Bacon, and which has introduced modern philosophers to a knowledge of the most secret and most sublime operations of nature.
