comment
In the central part of India there is represented the King Stephen, who is considered to be a Christian. Golden Crown gate, green dress and sitting in a curious way, crossing the left leg over the right, on a pillow slightly elevated from the ground. Holding a Golden Ball in his right hand and has the index on the left of the spot as if your bringing something.    In reality it is the Hindu Empire of Vijayanagar, created around 1340 in South India in opposition to the Sultanate of Delhi, Muslim. It is not a Christian dynasty, as stated in the text, but it is true that there were Christian colonies in the shopping malls, such as Quilon – today at the State of Kerala.   

The white flags, with the cross and Dove supposedly refer to Christian character of the Empire. The idea that there were Christian Kings in the Eastern Islamic world stems in large part from the legend of Ready John, but it is also true that Christian villages existed, although minority, which is believed to be the tomb of St. Thomas was at Mailapur near Madras, that the map appears as Mirapor.  There is no reference to the Indus River, the absence that also occurs in the writings of Marco Polo. The cause may be due to the confusion that often occurs between the Indus and the Ganges.
