Marco Polo's Voyage to Indian Seas: 32: The Kingdom of Semenat [1]

This is the great country to westward. The inhabitants are idolaters, with languages of their own, and a monarch subject to no other.  They are not pirates, but by the trade and industry, as good men aught to do. The country is rich and frequented by many merchants.  The people, however, are fierce and cruel idolaters.

Kesmacoran [2] is a kingdom with sovereign and a language of its own. The people are idolaters, and raise abundance of rice, on which and on flesh and milk, they subsist. There is a great trade by sea and land but nothing worth mentioning.  Now, this is the last province found in India in proceeding west and northwest; and all the kingdoms already described, from Maabar to this, that India which is called Greater, and is the first of anything in the world.  I have, however, only those on the seacoast, since to treat of the inland ones, would have been too tedious.  I shall therefore proceed to notice certain islands, also belonging to India, and the first called Male and Female.

Notes:-

1.  Semenat: A kingdom located in the region of Somanath in the state of Gujarat.  It was an important Hindu pilgrimage site, and is known for the magnificent Shiva Temple. It is situated between Veraval and Prabhas Patan. The latter is historically named Dev Patan.  The temple's considerable wealth was plundered by Mahmud of Ghazni, in 10th and eleventh century. Marco Polo does not mention anything about this, perhaps, he had been concentrating on ports and merchants or he was not aware of this. Before the rise of Surat, it was a prominent sea port for pilgrims to Mecca.

2. Kesmacoran: Likely areas including Karachi, Ormara and Gwadar.
