This is a thing which I have seen nowhere in the world except among the Indians of Malabar. But those are heathens; these people are Muslims, punctilious in observing the hours of prayer, studying books of law, and memorizing the Koran. Yet their women show no bashfulness before men and do not veil themselves, though they are assiduous in attending the prayers. Any man who wishes to marry one of them may do so, but they do not travel with their husbands, and even if one desired to do so her family would not allow her to go.
