Chapter II. Climate and Productions

Εστί αγαθά τοισι την ηπείρου εκείνην νεμομενοισι δσα ουδέ τοισι συναπασι αλλοισι, από χρυσού αρξαμενοισι αργυρός και χαλκος και εσθης ποικιλη και υποζύγια τε και ανδράποδα.  - Herod. v. 49.

It is evident that an Empire which extended over more than twenty degrees of latitude, touching on the one hand the tropic of Cancer, while it reached upon the other to the parallel of Astrakan, and which at the same time varied in elevation, from 20,000 feet above to 1300 below the sea level, must have comprised within it great differences of climate, and have boasted an immense variety of productions. No general description can be applicable to such a stretch of territory; and it will therefore be necessary to speak of the various parts of the Empire successively in order to convey to the reader a true idea of the climatic influences to which it was subject, and the animals, vegetables, and minerals which it produced.

Commencing with Persia Proper, the original seat and home of the race with whose history we are specially concerned at present, we may observe that it was regarded by the ancients as possessing three distinct climates—one along the shore, dry and scorchingly hot; another in the mountain region beyond, temperate and delightful; and a third in the tract further inland, which was thought to be disagreeably cold and wintry. Moderns, on the contrary, find two climates only in Fars—one that of the Desbistan or “low country,” extremely hot and dry, with frequent scorching and oppressive winds from the south and the south-east; the other, that of the highlands, which is cold in winter, but in summer pleasant and enjoyable. In the Deshistan snow never falls, and there is but little rain; heavy dews, however, occur at night, so that the mornings are often fresh and cool; but the middle of the day is almost always hot, and from March to November the temperature at noon ranges from 90° to 100° of Fahrenheit. Occasionally it reaches 125°, and is then fearfully oppressive. Fierce gusts laden with sand sweep over the plain, causing vegetation to droop or disappear, and the animal world to hide itself. Man with difficulty retains life at these trying times, feeling a languor and a depression of spirits which are barely supportable.10 All who can do so quit the plains and betake themselves to the upland region till the great heats are past, and the advance of autumn brings at any rate cool nights and mornings. The climate of the uplands is severe in winter. Much snow falls, and the thermometer often marks from ten to fifteen degrees of frost. From time to time there are furious gales, and, as the spring advances, a good deal of wet falls; but the summer and autumn are almost rainless. The heat towards midday is often considerable, but it is tempered by cool winds, and even at the worst is not relaxing. The variations of temperature are great in the twenty-four hours, and the climate is, so far, trying; but, on the whole, it seems to be neither disagreeable nor unhealthy.

A climate resembling that of the Deshtistan prevailed along the entire southern coast of the Empire, from the mouth of the Tigris to that of the Indus. It was exchanged in the lower valleys of the great streams for a damp close heat, intolerably stifling and oppressive. The upper valleys of these streams and the plains into which they expanded were at once less hot and less moist, but were subject to violent storms, owing to the near vicinity of the mountains. In the mountains themselves, in Armenia and Zagros, and again in the Elburz, the climate was of a more rigorous character—intensely cold in winter, but pleasant in the summer time. Asia Minor enjoyed generally a warmer climate than the high mountain regions; and its western and southern coasts, being fanned by fresh breezes from the sea, or from the hills of the interior, and cooled during the whole of the summer by frequent showers, were especially charming. In Syria and Egypt the heats of summer were somewhat trying, more especially in the Ghor or depressed Jordan valley, and in the parts of Egypt adjoining on Ethiopia; but the winters were mild, and the springs and autumns delightful. The rarity of rain in Egypt was remarkable, and drew the attention of foreigners, who recorded, in somewhat exaggerated terms, the curious meteorological phenomenon. In the Cyrenaica there was a delicious summer climate—an entire absence of rain, with cool breezes from the sea, cloudy skies, and heavy dews at night, these last supplying the moisture which through the whole of summer covered the ground with the freshest and loveliest verdure. The autumn and winter rains were, however, violent; and terrific storms were at that time of no unusual occurrence. The natives regarded it as a blessing, that over this part of Africa the sky was “pierced,” and allowed moisture to fall from the great reservoir of “waters above the firmament;” but the blessing must have seemed one of questionable value at the time of the November monsoon, when the country is deluged with rain for several weeks in succession.

On the opposite side of the Empire, towards the north and the north-east, in Azerbijan, on the Iranian plateau, in the Afghan plains, in the high flat region east of the Bolor, and again in the low plain about the Aral lake and the Caspian, a severe climate prevailed during the winter, while the summer combined intense heat during the day with extraordinary cold—the result of radiation—at night. Still more bitter weather was experienced in the mountain regions of these parts—in the Bolor, the Thian Chan, the Himalaya, and the Paropamisus or Hindu Kush—where the winters lasted more than half the year, deep snow covering the ground almost the whole of the time, and locomotion being rendered almost impossible; while the summers were only moderately hot. On the other hand, there was in this quarter, at the very extreme east of the Empire, one of the most sultry and disagreeable of all climates—namely, that of the Indus valley, which is either intolerably hot and dry, with fierce tornadoes of dust that are unspeakably oppressive, or close and moist, swept by heavy storms, which, while they somewhat lower the temperature, increase the unhealthiness of the region. The worst portion of the valley is its southern extremity, where the climate is only tolerable during three months of the year. From March to November the heat is excessive; dust-storms prevail; there are dangerous dews at night; and with the inundation, which commences in April, a sickly time sets in, which causes all the wealthier classes to withdraw from the country till the stagnant water, which the swell always leaves behind it, has dried up.

Upon the whole, the climate of the Empire belonged to the warmer class of the climates which are called temperate. In a few parts only, indeed, as in the Indus valley, along the coast from the mouth of the Indus to that of the Tigris, in Lower Babylonia and the adjoining portion of Susiana, in Southern Palestine, and in Egypt, was frost absolutely unknown; while in many places, especially in the high mountainous regions, the winters were bitterly severe; and in all the more elevated portions of the Empire, as in Phrygia and Cappadocia, in Azerbijan, on the great Iranian plateau, and again in the district about Kashgar and Yarkand, there was a prolonged period of sharp and bracing weather. But the summer warmth of almost the whole Empire was great, the thermometer probably ranging in most places from 90° to 120° during the months of June, July, August, and September. The springs and autumns were, except in the high mountain tracts, mild and enjoyable; the Empire had few very unhealthy districts; while the range of the thermometer was in most of the provinces considerable, and the variations in the course of a single day and night were unusually great, there was in the climate, speaking generally, nothing destructive of human vigor—nothing even inimical to longevity.

The vegetable productions of Persia Proper in ancient times (so far as we have direct testimony on the subject) were neither numerous nor very remarkable. The low coast tract supplied dates in tolerable plenty, and bore in a few favored spots, corn, vines, and different kinds of fruit-trees; but its general character was one of extreme barrenness. In the mountain region there was an abundance of rich pasture, excellent grapes were grown, and fruit-trees of almost every sort, except the olive, flourished. One fruit-tree, regarded as indigenous in the country, acquired a special celebrity, and was known to the Romans as the persica, whence the German Pfirsche, the French peche, and our “peach.” Citrons, which grew in few places, were also a Persian fruit. Further, Persia produced a coarse kind of silphium or assafoetida; it was famous for its walnuts, which were distinguished by the epithet of “royal”; and it supplied to the pharmacopeia of Greece and Rome a certain number of herbs.

The account of Persian vegetable products which we derive from antiquity is no doubt very incomplete; and it is necessary to supplement it from the observations of modern travellers. These persons tell us that, while Fars and Kerman are ill-supplied with forest-trees, they yet produce in places oaks, planes, chenars or sycamores, poplars, willows, pinasters, cypresses, acacias, fan-palms, konars, and junipers. Among shrubs, they bear the wild fig, the wild almond, the tamarisk, the myrtle, the box, the rhododendron, the camel’s thorn, the gum tragacanth, the caper plant, the benneh, the blackberry, and the...
