springflow are well‐attested, while on the borders of Khuzestan, Sistan, Kerman, and Baluchistan, arid conditions exist in which dry‐farming is impossible without the aid of irrigation. The northerly winds of the summer, coming almost entirely from the north, cause the region to become overheated. Extreme examples, such as the 120 days' wind in Sistan (Drangiana) or the shamal in Mesopotamia (Assyria, Babylonia) and the Gulf region (the satrapy of the Erythraean Sea and Maka), while useful for sailors, are inhibitors of agricultural development. Still, in coastal areas where agriculture was unviable except in winter, fishing and pearling, not to mention trading, were pursued in summer. Living with drought in the more southerly satrapies of the empire would have been the norm for six months of the year whereas in the more temperate latitudes a far more Mediterranean climate was conducive to continuous agricultural production, punctuated by severe winters with heavy frosts and snowfalls, rather than hyper‐arid summers.
Climate and topography necessarily had an enormous influence on flora and fauna throughout the Achaemenid Empire. Once again, given its size, it is scarcely surprising that the empire spanned the Mediterranean, Euro‐Siberian, western and central Asiatic, and Saharan‐Indian floristic zones. The more central portions of the empire contained an enormous range of flora, including desert, steppe, and semi‐desert vegetation; sub‐tropical savannah; Pistacia and Quercus woodlands; scrublands dominated by almond and juniper; conifer forests; and sub‐alpine and alpine vegetation (Breckle 2007). Following the last glaciation the Zagros and Alburz mountains in Iran and the Hindu Kush/northern Afghanistan provided refuge for a large number of tree species, many of which later spread across Iran, Anatolia, and into Europe. Indications of ancient environments within the Achaemenid Empire are provided by both Achaemenid epigraphic and Greek literary sources as well as archeological data.
One of the most well‐known Achaemenid sources is Darius' exposition (DSf) of the materials used in the construction of his palace at Susa (Lecoq 1997: pp. 234–237). According to Darius, the cedar used in the palace came from the mountains of Lebanon; the sissoo wood (OP yakâ; see Gershevitch 1957) from Gandhara (northwest Pakistan) and Kerman (southeastern Iran); and the ebony (Dalbergia melanoxylon) from Egypt. In ancient usage, however, it is often the case that the geographical descriptor attached to a commodity is the supplier of the material rather than the actual land in which it grew or was mined. This is true in the case of Darius' ebony, the actual provenance of which was probably somewhere in sub‐Saharan Africa (the current range extends from Senegal in the west to Eritrea/northern Ethiopia in the east and to Angola and the Transvaal in the south; see Hepper 1996: p. 6).
Minerals used in the palace at Susa included gold from Lydia, probably the alluvial gold of the Pactolus river (Muhly 1983: p. 7) or the slopes of nearby Mt. Tmolus (Forbes 1939: p. 244), and Bactria (northern Afghanistan and southern Uzbekistan); lapis lazuli and carnelian (?) from Sogdia; and turquoise from Chorasmia. It is doubtful whether the lapis lazuli mines at Sar‐e Sang in the Hindu Kush mountains of northern Afghanistan, the major source in all periods of ancient Near Eastern history, lay within the bounds of Sogdia, which centered on the Ferghana Valley further north in what today is Uzbekistan. Herzfeld reckoned the mines were located in eastern Bactria (Herzfeld 1968: p. 323). It is perfectly reasonable to suppose, however, that the Sogdians had access to lapis lazuli from Sar‐e Sang, though not that they necessarily controlled its extraction as has sometimes been assumed (La Vaissière 2004: p. 22). It is also questionable whether high‐quality carnelian was available anywhere in Sogdia and more likely that if carnelian is indeed the correct translation of the term in question (OP sinkabru, El. sinkabruš, Akk. Ṣingabrû), it came from Gujarat (La Vaissière 2004: p. 21). Herzfeld suggested that carnelian was not meant here at all. Rather, he drew a parallel between the ancient term and cinnabar and suggested that this was “used for making the colours of the enamelled bricks of Susa” (Herzfeld 1968: p. 323, no. 3). As Pliny noted (Nat. Hist. 29.8), cinnabar (Gr. κιννάβαρι) or mercuric sulfate (HgS), was often confused in antiquity with minium, or lead oxide (Pb3O4), which was indeed a source of red pigment (Theophrastus, De Lapidibus 8.60; Eichholz 1965: p. 128). Although in the Roman and medieval periods lead oxide came mainly from Spain (Porter and Vesel 1993: p. 147; cf. Strabo, Geog. 12.2.10, where the Iberian is said to rival the Cappadocian variety), another source must have been available to the Achaemenids, for analyses of glazed bricks in the Louvre, presumably originating in Darius' palace or one of the later royal Achaemenid buildings at the site (Boucharlat 2010: pp. 374–384), have shown the presence of lead oxide (Bouquillon et al. 2007: pp. 132–134). Interestingly, mercury was detected in some of the bricks in the so‐called Šāhūr palace of Artaxerxes II at Susa and this implies a source of cinnabar from which mercury was obtained (Boucharlat 2010: p. 408). The Chorasmian turquoise cited by Darius most probably came from the mines in the Kyzyl Kum, southeast of the Aral Sea and north of Zerafshan (Tosi 1974: pp. 149–150).
Turning to some of the Greek literary sources, Xenophon's Anabasis is replete with geographical and topographic information, including the names of rivers crossed and places visited, but when describing, for example, Cyrus the Younger's passage from Cilicia to Thapsacus on the Euphrates, it scarcely offers any description of the country traversed (Xenophon, Anab. 1.4.11). Upon reaching “Arabia,” i.e. northern Mesopotamia (Donner 1986), more description is given. According to Xenophon, “In this region the ground was entirely a plain, level as the sea. It was covered with wormwood, and whatever other kinds of shrub or reed grew on it, were all odoriferous as perfumes. But there were no trees. There were wild animals, however, of various kinds; the most numerous were wild asses [onagers, Equus hemionus]; there were also many ostriches, as well as bustards and antelopes” (Anab. 1.5.1–2). Further south, as they approached Babylonia proper, “there was neither grass, nor any sort of tree, but the whole country was completely bare. The inhabitants, who quarried and fashioned millstones near the river [Euphrates], took them to Babylon, and sold them, and lived upon corn which they bought with the money” (Anab. 1.5.5). This extreme barrenness is a perfectly accurate description for the time of year in which Cyrus' passage into Babylonia occurred. This has been dated to the very end of August (Watson and Ainsworth 1883: p. 260), which, with respect to the ancient Mesopotamian agricultural calendar, was after the annual harvest in July/August (Potts 1997: Table III.1). Some scholars have been puzzled by the absence of any reference to pastoral nomads and their herds in this description (e.g. Donner 1986), but from the general floral, faunal, environmental, and agricultural point of view, the description accords well with the semi‐arid nature of the steppic environment in this region during the late summer. In the fourteenth/fifteenth centuries, Turcoman nomads, such as the Aq‐qoyunlu, wintered in precisely this area – the steppe between Mosul on the Tigris and Raqqah and Bireçik on the Euphrates, north as far as Diyarbakır – but summered further north over an area extending from the east of Erzurum to the west of Erzincan, and almost as far north as the Black Sea (Woods 1999: Map 2). It is likely, therefore, that when Cyrus the Younger passed through, any pastoral nomads that might have frequented the region in winter had long since moved north to more temperate areas in Anatolia.
Later Greek sources compiled in the wake of Alexander's conquest provide a snapshot of environments found in the different satrapies of the Achaemenid Empire, naming rivers, mountain ranges, and other notable physical features as well as resources. The lost but heavily cited Geographika of Eratosthenes (Roller 2010), the later compendium of Strabo (Biffi 2002), and the histories of Alexander's campaigns (especially Arrian's Anabasis) are invaluable sources of material on the landscapes of the late Achaemenid Empire. Even some of the most arid regions, like Gedrosia, produced economically (and medicinally) important resources. The flora of Gedrosia was described in considerable detail by Theophrastus (Theophrastus, Hist. Plant. 4.4.12–13; cf. Arrian, Anab. 6.22.4–8; Strabo, Geog. 15.2.3; Pliny, Nat. Hist. 12.33) and included, in the interior, a myrrh‐like aromatic (bdellium), triangular spurge (Euphorbium antiquorum), spikenard (sweet rush or ginger grass, Cymbopogon schoenanthus), asafoetida (Scorodosma foetidum), oleander (Nerium odorum), and the date palm (Phoenix dactylifera) as well as mangrove (Avicennia marina) along the coast (Eggermont 1975: pp. 120–125; cf. Bretzl 1903). Many of these species were found
