In the early Islamic period, Khorasan was referred to as “Place of Sunrise” that stretched from the eastern side of the Lut Desert to the Hindukush Mountains. This region was divided into four parts or “quarters” of Neyshabour, Merv, Herat, and Balkh during the early centuries of Islam. The region that finally became the capital of Taherid dynasty was one of the important political, religious, and geographical centers during those years. A New York Metropolitan Museum’d expedition under Charles Carl Wilkinson was carried out on 3,500-hectare area of the ancient city of Neyshabour, from 1937 to 1948 AD.
