From the narrations of different travellers it would seem that the Parsis had settled in a great many cities of Upper India; but it is impossible to say whether these came from Western India or from Persia. A Mahomedan traveller of the tenth century, Al Isthakhri, mentions several parts of India as being occupied by the Guebres: that is the name given by Mahomedan writers to the Parsis. An unexceptionable testimony of their presence at Dehra-Dun (1079) is furnished to us in the attack of Ibrahim the Ghaznevid against a colony of fire-worshippers living in that place. Similarly we find the Parsis in the Panjaub before 1178, if we are to believe the tradition of a voyage made that year by a Parsi priest named Mahyar; he had come from Uch, a town situated on the conflux of the five rivers of the Panjaub, to Seistan in Persia, in order to acquire a thorough knowledge of the religious rites. After six years of study under the Dastoors he brought into India, in 1184, a copy of the Pehlvi translation of the Vendidad. [26] It seems also that there must have been some intercourse between the Parsis of Cambay and those of the Panjaub, since, in 1328, the former were in possession of some copies of the Vendidad acquired by Mahyar. At the time of the invasion of India by Timur, we find Parsis or Magi amongst the captives. The men who have been represented as believing in the two principles of good and evil, and admitting at the same time Yazdan (God) and Ahreman (the Devil), and who offered a desperate resistance to Timur at Tughlikhpur, were the Parsis. It is said besides that the colony at Gujerat was reinforced by a large number of Parsis, who fled before the conqueror. The mention made by a Mahomedan writer of the destruction of fire-temples by the Emperor Sikandar (1504), shows that long before this date Parsi emigrants had dwelt in Upper India. Sir H. M. Elliot, in his History of India, following the opinion of Professor Dawson, affirms that the Guebres of Rohilkhand, the Magyas of Malwa, and the Maghs of Tughlikhpur, although at present they offer no religious peculiarities, are the remnants of the Parsis of Upper India. According to a communication anent Mount Abu by Sir Alexander Burnes, cited in the Gazetteer of Bombay, there had been a Parsi colony at Chandrauli towards the middle of the fifteenth century. It is believed that the Parsis settled at Ankleswar in the middle of the thirteenth century of our era. One of their religious books, the Vispered, was in fact copied there in 1258. There is no doubt of their having been at Bharooch [27] before the commencement of the fourteenth century, for we find that a "Dokhma" was built there in 1309 by a Parsi named Pestanji; and the ruins of a still older Tower are to be found in the suburb of Vajalpoor.
