The position of Minnagara has occupied the attention of geographers from D’Anville to Pottinger. Sind being conquered by Omar, general of the caliph Al-Mansur (Abbasi), the name of Minnagara was changed to Mansura, “une ville célèbre sur le rivage droit du Sind ou Mehran.” “Ptolémée fait aussi mention de cette ville; mais en la déplaçant,” etc. D’Anville places it about 26°, but not so high as Ulug Bég, whose tables make it 26° 40´. I have said elsewhere that I had little doubt that Minnagara, handed down to us by the author of the _Periplus_ as the μετρόπολις τῆς Σκυθίας, was the Saminagara of the Yadu Jarejas, whose chronicles claim Seistān as their ancient possession, and in all probability was the stronghold (_nagara_) of Sambos, the opponent of Alexander. On every consideration, I am inclined to place it on the site of Sehwan. The learned Vincent, in his translation of the _Periplus_, enters fully and with great judgment upon this point, citing every authority, Arrian, Ptolemy, Al-Biruni, Edrisi, D’Anville, and De la Rochette. He has a note (26, p. 386, vol. i.) which is conclusive, could he have applied it: “Al-Birun [equi-distant] between Debeil and Mansura.” D’Anville also says: “de Mansora à la ville nommée Birun, la distance est indiquée de quinze parasanges dans Abulféda,” who fixes it, on the authority of Abu-Rehan (surnamed Al-Biruni from his birthplace), at 26° 40´. The ancient name of Haidarabad, the present capital of Sind, was Nerun (نيرون;) or Nirun, and is almost equi-distant, as Abulfeda says, between Debal (Dewal or Tatta) and Mansura, Sehwan, or Minnagara, the latitude of which, according to my construction, is 26° 11´. Those who wish to pursue this may examine the _Éclaircissemens sur la Carte de l’Inde_, p. 37 _et seq._, and Dr. Vincent’s estimable translation, p. 386. [The site of Minnagara, like those of all the cities in the delta of the Indus, owing to changes in the course of the river, is very uncertain. Jhajhpur or Mungrapur has been suggested (McCrindle, _Ptolemy_, 72, _Periplus_, 1086 f.). Nīrūn has been identified with Helāi, a little below Jarak, on the high road from Tatta to Haidarābād (Elliot-Dowson i. 400).] Footnote 4.1.32: See _History of the Tribes_, p. 107, and translation of Inscription No. I. _Vide_ Appendix. Footnote 4.1.33: Considerable intercourse was carried on between the princes of India and China from the earliest periods; but particularly during the dynasties of Sum, Leam and Tam, from the fourth to the seventh centuries, when the princes from Bengal and Malabar to the Panjab sent embassies to the Chinese monarchs. The dominions of these Hindu princes may yet be identified.
