fourth to eighth centuries - consistently evoke the name of local deities, such as Kamird and Wakhsh, for example, as witnesses to contracts. The documents come from an area between Balkh and Bamiyan, which is part of Bactria. Buddhism Balkh is well known to Buddhists as the hometown of Trapusa and Bahalika, two merchants who, according to scripture, became Buddha's first disciples. They were the first to offer Buddha food after he attained enlightenment, and in return Buddha gave them eight of his hairs to remember him by. According to some accounts, Trapusa and Bahalika returned to Balkh, and built two stupas in the way Buddha instructed. Balkh is therefore named after Bahalika, who is credited with introducing Buddhism to the city. This is reflected in literature, where the town has been called Balhika, Bahlika or Valhika. The first Buddhist monastery (vihara) at Balkh was built for Bahalika when he returned home after becoming a Buddhist monk. The Chinese pilgrim Faxian (337-422 CE) traveled to the region in the early 5th century, and found Hinayana Buddhism prevalent in Shan Shan, Kucha, Kashgar, Osh, Udayana and Gandhara. Later, the Chinese monk Xuanzang (602–664 CE) visited Balkh in 630 CE, when it was a flourishing centre of Hinayana Buddhism. According to his memoirs, there were about a hundred Buddhist convents in the city or its vicinity at the time of his visit. There were 3,000 monks and a large number of stupas and other religious monuments. Xuanzang also remarked that Buddhism was widely practiced by the Hunnish rulers of Balkh, who were descended from Indian royal stock. During the 8th century, the Korean monk and traveler Hyecho (704–787 CE) recorded that even after the Arab invasion, the residents of Balkh continued to practice Buddhism and followed a Buddhist king. He noted that the king of Balkh at the time had fled to nearby Badakshan. The most remarkable Buddhist monastery was the Nava Vihara ("New Temple"), which possessed a gigantic statue of Gautama Buddha. Located near the city of Balkh, it served as a pilgrimage centre for political leaders who came from far and wide to pay homage to it. Shortly before the Arab conquest, the monastery became a Zoroastrian fire-temple. A curious reference to this building is found in the writings of the geographer Ibn Hawqal, an Arab traveler of the 10th century, who describes Balkh as built of clay, with ramparts
