stiff rituals of a Near Eastern court and of assemblies of wild horsemen wheeling beneath the open sky, of ancient cities and of the hills and plains, of the Persians' future and of the memories and customs of their past, Cyrus was adept at playing all these roles, and more. As a result, Persia had largely avoided the tensions that afflicted Media: between a king impatient with the traditional tribal structures of his people and a nobility still defined by them. The Median clan chiefs, suffering from the authoritarian ambitions of Astyages, had taken note. Over time, the contrast between their own king and Cyrus must have struck them as ever more pronounced. It was almost certainly this which had persuaded Harpagus to take his fateful step. 'So it was that the Persians, who had once been the slaves of the Medes, became their masters,' 17 and Cyrus, marching into Ecbatana, reaped the due rewards of his forbearance, acuity and charm.
Nor, even after this first great victory, did the subtlety of his balancing act fail. The kings of Assyria, honing the traditional rights of conquest to a peak of savagery, had prescribed unspeakable cruelties for defeated enemies, but Cyrus, prompted by calculation and — no doubt-by temperament as well, preferred the course of mercy. Having lured important swaths of the Median aristocracy into his camp, he resisted the temptation to treat their countrymen as slaves. Even Astyages, rather than being flayed, fed to animals or impaled, was pensioned off into princely retirement. True, the treasury was emptied and its contents carted away to Anshan, but Ecbatana was otherwise spared the fate of Nineveh. Cyrus had no intention of destroying the most strategically sited city in the Zagros. The most pleasant, too — for if, in winter, the cold was savage, with blizzards blocking off the passes, in summer, while the lowlands of Persia burned, Ecbatana was a paradise of greenness, the mountain peaks behind it still capped with cooling snow, the slopes below the walls terraced with orchards and gardens, the air bright and crystal-clear. Not only did the city remain the capital of Media, but it became, during the broiling summer months, the effective capital of Cyrus' whole empire. No wonder that the Medes were able to feel, if not exactly the equals of their conquerors, then at least associates in the great adventure of their new king's reign.
And that adventure, as events were soon exhilaratingly to prove, had only just begun. The downfall of a king as great as Astyages had sent shock waves throughout the whole Near East. Not only the Median Empire but the decades-old international status quo had been left in rubble. Suddenly, it seemed, there was everything to play for, and neighbouring great powers, still barely able to take the Persians seriously, began to wonder what pickings might be on offer for themselves. In 547 bc , Croesus, the King of Lydia, led a huge army over the River Halys to find out. Cyrus, having descended from the Zagros, advanced hurriedly to meet him, the ruined cities of Assyria standing sentinel as he passed by, nothing now but dust-blown and jumbled heaps of mud, mute witnesses to the precariousness of power. Yet such a lesson might serve an ambitious man as inspiration as well as warning, and Cyrus, even though it was by now late in the campaigning season, pressed on urgently, eager to engage Croesus. As before, when the Lydians had met with the Medes, an indecisive battle was fought; but this time there was no eclipse, and no end to the war. Instead, with winter drawing on, Croesus withdrew to his capital, Sardis, never imagining that Cyrus would dare to follow him, for the city was so far to the west that the Aegean lay only three days' journey beyond it — a tremendous distance from the Median frontier. But the Persians did not retreat. Instead, braving the bitter cold, they shadowed Croesus, never alerting him to their presence, allowing him time to dismiss his allies,
