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 liquorice-plant. They boast a great abundance of fruit-trees—as date-bearing palms, lemons, oranges, pomegranates, vines, peaches, nectarines, apricots, quinces, pears, apples, plums, figs, cherries, mulberries, barberries, walnuts, almonds, and pistachio-nuts. The kinds of grain chiefly cultivated are wheat, barley, millet, rice, and Indian corn or maize, which has been imported into the country from America. Pulse, beans, sesame, madder, henna, cotton, opium, tobacco, and indigo, are also grown in some places. The three last-named, and maize or Indian corn, are of comparatively recent introduction; but of the remainder it may be doubted whether there is a single one which was unknown to the ancient inhabitants.
Among Persian indigenous animals may be enumerated the lion, the bear, the wild ass, the stag, the antelope, the ibex or wild goat, the wild boar, the hyena, the jackal, the wolf, the fox, the hare, the porcupine, the otter, the jerboa, the ichneumon, and the marmot. The lion appears to be rare, occurring only in some parts of the mountains. The ichneumon is confined to the Deshtistan. The antelope, the wild boar, the wolf, the fox, the jackal, the porcupine, and the jerboa are common. Wild asses are found only on the northern side of the mountains, towards the salt desert. In this tract they are frequently seen, both singly and in herds, and are hunted by the natives, who regard their flesh as a great delicacy.
The most remarkable of the Persian birds are the eagle, the vulture, the cormorant, the falcon, the bustard, the pheasant, the heath-cock, the red-legged partridge, the small gray partridge, the pin tailed grouse, the sand-grouse, the francolin, the wild swan, the flamingo, the stork, the bittern, the oyster-catcher, the raven, the hooded crow, and the cuckoo. Besides these, the lakes boast all the usual kinds of water-fowl, as herons, ducks, snipe, teal, etc.; the gardens and groves abound with blackbirds, thrushes, and nightingales; curlews and peewits are seen occasionally; while pigeons, starlings, crows, magpies, larks, sparrows, and swallows are common. The francolin is hunted by men on foot in the country between Shiraz and Kerman, and is
