After these Kadphiseses came, probably, Kanishka. Inscriptions referring to him (or to the era which supposedly began with his accession) are found over a vast area extending from the Oxus frontier of Afghanistan to Varanasi and Sanchi. Tradition further testifies to his conquest of Magadha and to vast responsibilities in and beyond the western Himalayas, including Kashmir and Khotan in Sinkiang. Buddhist sources, to which we are indebted for much of this information, hail him as another Menander or Ashoka; he showered the sangha (the monastic community) with patronage, presided over the fourth Buddhist council and encouraged a new wave of missionary activity. At Purushpura, or Peshawar, his capital still boasts the foundations of a truly colossal stupa. Nearly a hundred metres in diameter and reliably reported to have been two hundred metres high, it must have ranked as one of the then wonders of the world.
Mathura on the Jamuna seems to have served as a subsidiary capital, and nearby have been found suitably massive statues of Wima Kadphises and of Kanishka himself. Unfortunately both have been decapitated. While for the Greeks, thanks to their coins, we have notable heads but few torsos, for the Kushanas we have notable torsos but few heads. Kanishka stands in challenging pose, his outsize feet encased in quilted felt boots and splayed outwards. The full-frontal presentation reveals a belted tunic beneath a stiff ankle-length coat that looks as if it could have been of leather. One hand rests on a grounded sword of skull-splitting potential, the other clutches an elaborate contraption sometimes described as a mace but which could equally be some kind of crossbow. Hopelessly overdressed for the Indian plains and most un-Indian in its angular and uncompromising posture, this statue evokes the harsh landscapes whence the Kushana came and where, while campaigning in Sinkiang, Kanishka is said to have died. Although surely not ‘one of the finest works of art produced on Indian soil’, his statue is indeed ‘unique as the only Indian work of art to show a foreign stylistic influence that has not come from Iran or the Hellenistic or Roman world’.6
Kanishka’s successors, many with names also ending in ‘-ishka’, continued Kushana rule for another century or more. As with other august dynasties, their territories are assumed to have shrunk as their memorials became fewer and nearer between; in the course of time the Kushanas dwindled to being just one of many petty kingdoms in the north-west. Unfortunately it is impossible to be precise about their chronology since all inscriptions are dated from the accession of Kanishka, itself a subject of yawning complexity which numerous international gatherings on several continents have failed to resolve. Today’s Republic of India, as well as having two names for the country (India and Bharat), has two systems of dating, one the familiar Gregorian calendar of BC/AD and the other based on the Shaka era which is reckoned to have begun in 78 AD. Although called ‘Shaka’ (rather than ‘Kushana’), this era is supposed by many to correspond with the Kanishka era. Others have tried to match Kanishka with another Indian era, the Vikrama, which began in 58 BC. This seems much too early. On the other hand the latest scholarship, based on numismatic correlations between Kushana and Roman coins, pushes Kanishka’s accession way forward to about 128 AD.
Clearly these variations are significant. Were Kanishka’s dates certain, it might be possible to be a little more dogmatic about his achievements, although the same can hardly be said of his elusive successors. If there has to be a blind summit somewhere along north India’s chronological highway, the second to third centuries AD would seem as good a place as any. Should, however, the controversy be resolved, it could mean whole-scale revision of our understanding of the preceding centuries; upgrading even chronological highways can have dramatic results.
ACROSS THE ROOF OF THE WORLD
When Pakistani and Chinese engineers began construction of a road link between their two countries in the late 1970s, eyebrows were raised in Delhi and elsewhere. The planned ‘Karakoram Highway’ was seen as evidence of a menacing alignment between Mao-tse Tung’s China and Zulfiqar Ali Bhutto’s Pakistan. As well as being politically sinister and strategically unprecedented, it was thought geographically perverse. For if ever there was a frontier decreed by nature it was the Himalayan chain. This, after all, was India’s Great Wall; behind it the peoples of the subcontinent had traditionally sheltered from the whirlwinds of migration and conquest which ceaselessly swept the arid pastures beyond. Moreover, nowhere was this wall more formidable than at its western bastion where, in the far north of Pakistan, the Great Himalaya becomes entangled in the pinnacles of the Hindu Kush and the glaciers of the mighty Karakoram. Extremes of temperature, colossal natural erosion, frequent seismic activity and recent glacial acceleration also make this the most unstable region on earth. Breaching the rampart with the viaducts, tunnels and easy gradients of an all-weather, two-lane highway looked to be short-sighted, provocative and exceedingly challenging.
Nevertheless, at fearful cost in lives and plant, the road was built. ‘The eighth wonder of the world’ was duly hailed, and convoys of battered trucks and buses began occasionally to emerge at its either end after eventful days of motoring across ‘the roof of the world’. The benefits have been mixed. At five thousand metres above sea-level, the Sino – Pakistan border on the blizzard-swept Khunjerab Pass has witnessed a modest flow of trade but little other intercourse. The road has been more of a boon to the isolated mountain communities of Pakistan’s ‘Northern Areas’, although the discreet charms of their valleys have been prejudiced in the process. Only to archaeologists and historians has the road opened a wholly welcome perspective.
That from India the teachings of the Buddha had originally spread to China via central Asia had long been known. The Han dynasty had opened trade with the West via the so-called Silk Route in the second century BC; the Route ran north of Tibet, on through Sinkiang and then down the Oxus through Bactria to Bukhara, Iran and the Mediterranean. The Han dynasty had also been in diplomatic contact with the Yueh-chi long before the latter, as Kushanas, entered India. Later, when Kushana dominion spread in a great arc from Sinkiang through Afghanistan and across the Indus into India, an obvious India–China conduit was created. Additionally Kanishka had clearly revived Ashoka’s policy of patronising the Buddhist sangha and promoting the spread of Buddhist doctrine. From Chinese sources it was even known that the first Buddhist missionaries to China had set out from India in 65 AD. It was therefore probably under the Parthians or the Kushanas that the monks Dharmaraksa and Kasyapa Matanga had made their way to China, there to found the first monastery and begin their work of preaching and translating the sacred doctrines. In their footsteps would follow the procession of teachers and artists, of icons, texts and relics which over the next three hundred years would nurture the new faith and diffuse new art forms in China and beyond.
Traditionally their route is supposed to have proceeded from Peshawar to Kabul and over the Hindu Kush via Bamiyan, a tight valley above which two gigantic statues of the Buddha were carved high in the vertical cliffs. There they stood for 1500 years until in March 2001 Taliban zealots tested them with anti-tank mines, targeted them with artillery and finally toppled them with dynamite. (Exactly six months later Bamiyan’s twin Buddhas were followed to extinction by New York’s ‘twin towers’; the first outrage inspired the second and has often been attributed to the same agency.) Other remains in Bactria itself still attest the Buddhist presence, and thence north and east across the Pamirs, round the desert of Takla Makan and across Lop Nor a succession of Buddhist sites marks the trail to China. ‘The road is long,’ reported a later Chinese pilgrim who had made the return journey to India; looping laboriously right round that mountain bastion of India’s ‘Great Wall’ it is all of three thousand kilometres. There is no doubt that it was indeed an important route for the traffic of both ideas and commodities; but what the road-builders in the 1970s discovered was that there had been a shorter and better signposted route by way of the upper Indus and Hunza rivers along the line of their Karakoram Highway.
As reconstructed by Dr Ahmad Hasan Dani, Pakistan’s leading archaeologist, the historical trail begins north of Taxila, where the modern highway strikes off into the hills. Suitably enough the first ‘signpost’ is a Kharosthi version of Ashoka’s Major Rock Edict engraved on two badly weathered boulders at Mansehra. The road runs between them and, in view of the incidence of other Ashokan inscriptions at major route intersections, it seems safe to infer that the Indus
