What is "minnagara"

Minnagara was an ancient port located in what is now the modern city of Karachi, in the Sindh province of Pakistan. Minnagara was a city of the Indo-Scythian kingdom, located on the Indus river in modern Pakistan, north of the coastal city of Barbaricum, or along the Narmada river, upstream of Barigaza. There were two cities named Minnagara, one on Indus River delta near Karachi and the other at Narmada River delta near modern Bharuch.

Minnagara is mentioned in the 1st century CE Periplus of the Erythraean Sea:

"Beyond this region ( Gedrosia), the continent making a wide curve from the east across the depths of the bays, there follows the coast district of Scythia, which lies above toward the north; the whole marshy; from which flows down the river Sinthus, the greatest of all the rivers that flow into the Erythraean Sea, bringing down an enormous volume of water (...) This river has seven mouths, very shallow and marshy, so that they are not navigable, except the one in the middle; at which by the shore, is the market-town, Barbaricum. Before it there lies a small island, and inland behind it is the metropolis of Scythia, Minnagara."

A second Minnagara is mentioned in the Periplus, which seems to be upstream of Barigaza:

Ptolemy also mentioned Minnagara, which, according to his explanations, would be along the Narmada river, upstream of Barigaza, and below Ujjain:

Minnagara may be identical with the Manjábarí of the Arab geographers.

Alternatively, "Nagara" being the Sanskrit word for "town", the city itself may have been called "Min", a name found in Isidorus of Charax as a Scythian city in Sakastan (Lassen).
