Rediscovery
By the time Gandhara had been absorbed into the empire of Mahmud of Ghazni, Buddhist buildings were already in ruins and Gandhara art had been forgotten. After Al-Biruni, the Kashmiri writer Kalhaṇa wrote his book Rajatarangini in 1151. He recorded some events that took place in Gandhara, and gave details about its last royal dynasty and capital Udabhandapura.
In the 19th century, British soldiers and administrators started taking interest in the ancient history of the Indian Subcontinent. In the 1830s coins of the post-Ashoka period were discovered and in the same period Chinese travelogues were translated. Charles Masson, James Prinsep, and Alexander Cunningham deciphered the Kharosthi script in 1838. Chinese records provided locations and site plans of Buddhists shrines. Along with the discovery of coins, these records provided necessary clues to piece together the history of Gandhara. In 1848 Cunningham found Gandhara sculptures north of Peshawar. He also identified the site of Taxila in the 1860s. From then on a large number of Buddhist statues have been discovered in the Peshawar valley.
John Marshall performed an excavation of Taxila from 1912 to 1934. He discovered separate Greek, Parthian, and Kushan cities and a large number of stupas and monasteries. These discoveries helped to piece together much more of the chronology of the history of Gandhara and its art.
After 1947 Ahmed Hassan Dani and the Archaeology Department at University of Peshawar made a number of discoveries in the Peshawar and Swat Valley. Excavation on many sites of the Gandhara Civilization are being done by researchers from Peshawar and several universities around the world.
