From 'Marco Polo' by Isaac Asimov published in 1926

When strangers arrive in Kamul, and desire to have lodging and accommodation at their houses, it affords them the highest gratification. They give positive orders to their wives, daughters, sisters, and other female relations, to indulge their guests in every wish, whilst they themselves leave their homes, and retire into the city, and the stranger lives in the house with the females as if they were his own wives, and they send whatever necessaries may be wanted; but for which, it is to be understood, they expect payment: nor do they return to their houses so long as the strangers remain in them.

This abandonment of the females of their family to accidental guests, who assume the same privileges and meet with the same indulgences as if they were their own wives, is regarded by these people as doing them honour and adding to their reputation; considering the hospitable reception of strangers, who after the perils and fatigues of a long journey, stand in need of relaxation, as an action agreeable to their deities, calculated to draw down the blessing of increase upon their families and to procure them safety from all dangers.

The women are in truth very handsome, very sensual, and fully disposed to conform in this respect to the injunction of their husbands.

It happened at the time when Mangu Kaan held his court in this province, that the above scandalous custom coming to his knowledge, he issued an edict strictly commanding the people of Kamul to relinquish a practice so disgraceful to them, and forbidding individuals to furnish lodging to strangers, but to provide hostelries for travelers.

In grief and sadness the inhabitants obeyed for about three years the command of their master; but finding at length that the earth ceased to yield the accustomed fruits, and that many unfortunate events occurred in their families, they resolved to despatch a deputation to the Mangu Kaan, in their names, to beseech him that he should be pleased to suffer them to resume the observance of a custom that had been solemnly handed down to them by their fathers, from their ancestors in the remotest times.

The Kaan, having listened to this application, replied: "Since you appear so anxious to persist in your own shame, let it be granted as you desire. Go, live according to your base customs and manners, and let your wives continue to receive the beggarly wages of their prostitution." With this answer the deputies returned home, to the great delight of all the people, who, to the present day, observe their ancient practice.
